Organic chemistry is a core part of the chemistry curricula, andadvanced levels texts often obscure the essential frameworkunderlying and uniting the vast numbers of reactions as a result ofthe high level of detail presented. The material in this book iscondensed into a manageable text of 350 pages and presented in aclear and logical fashion, focusing purely on the basics of thesubject without going through exhaustive detail or repetitiveexamples. The book aims to bridge the gap between undergraduateorganic chemistry textbooks and advanced level textbooks, beginningwith a basic introductory course and arranging the reactionmechanisms according to an ascending order of difficulty. As such,the author believes the book will be excellent primer for advancedpostgraduates Reaction Mechanisms in Organic Synthesis is written fromthe point of view of the synthetic organic chemist, enablingstudents and researchers to understand and expand on reactionscovered in foundation courses, and to apply them in a practicalcontext by designing syntheses. As a further aid to the practicalresearch student, the content is organized according to theconditions under which a reaction is executed rather than by thetypes of mechanisms. Particular emphasis is placed on controllingstereospecificity and regiospecificity. Topics covered include: Transition metal mediated carbon-carbon bond formationreactions Use of stabilized carbanions, ylides and enamines forcarbon-carbon bond formation reactions, Advanced level use of oxidation and reduction reagents insynthesis. As a modern text, this book stands out from its competitors dueto its comprehensive coverage of recently published research. Thebook contains specific examples from the latest literature,covering modern reactions and the latest procedural modifications.The focus on contemporary and synthetically useful reactionsensures that the contents are specifically relevant and attractiveto postgraduate students and industrial organic chemists.

Most reactions in organic chemistry do not proceed in a single step but rather take several steps to yield the desired product. In the course of these multi-step reaction sequences, short-lived intermediates can be generated that quickly convert into other intermediates, reactants, products or side products. As these intermediates are highly reactive, they cannot usually be isolated, but their existence and structure can be proved by theoretical and experimental methods. Using the information obtained, researchers can better understand the underlying reaction mechanism of a certain organic transformation and thus develop novel strategies for efficient organic synthesis. The chapters are clearly structured and are arranged according to the type of intermediate, providing information on the formation, characterization, stereochemistry, stability, and reactivity of the intermediates. Additionally, representative examples and a problem section with different levels of difficulty are included for self-testing the newly acquired knowledge. By providing a deeper understanding of the underlying concepts, this is a musthave reference for PhD and Master Students in organic chemistry, as well as a valuable source of information for chemists in academia and industry working in the field. It is also ideal as primary or supplementary reading for courses on organic chemistry, physical organic chemistry or analytical chemistry.

InTroduCTIon This seventh edition of Organic Chemistry significantly extends the transformation started in the sixth edition. Students taking an organic chemistry course have two objectives: the first is to learn organic chemistry, and the second is to establish the intellectual foundation for other molecular science courses. Most often, these other courses involve biochemistry or specialized topics such as materials science. This textbook addresses these two objectives head-on by first presenting mechanistic and synthetic organic chemistry geared toward giving students a fundamental understanding of organic molecules and reactions as well as their mechanisms and uses in organic synthesis. The text then builds on the fundamentals by emphasizing bridging concepts that will prepare students for subsequent science courses. Several studying and learning features of this text include comprehensive end-of-chapter summaries, a unique paradigm for learning mechanisms, and an enhanced learning tool called Organic Chemistry Reaction Roadmaps. A FrESH Look AT MECHAnISMS This edition refines a revolutionary paradigm for learning organic chemistry mechanisms. Students are introduced to a small set of individual mechanism elements in a special primer section preceding Chapter 6. In addition, a new special primer section just before Chapter 18 describes how to apply this unique approach to construct the mechanisms for the reactions of carboxylic acid derivatives, historically the make-or-break point for students learning to develop and understand complex reaction mechanisms in the organic chemistry course. In both of these new special sections, the mechanism elements are explained in detail, including when they are appropriate to use. Reaction mechanisms throughout the rest of the book are described as combinations of these individual mechanism elements, which are written in stepwise fashion. This new approach not only simplifies the learning of mechanisms for students but also makes it easier to recognize similarities and differences between related reactions. Most important, it makes the prediction of reaction mechanisms simpler, analogous to a multiple-choice situation in which the correct mechanism element is chosen from a menu of choices. Also, Appendix 10, “Common Mistakes in Arrow Pushing,” gives students more hints on writing mechanisms. To reinforce the mechanism element approach, the uniting concept of nucleophiles reacting with electrophiles is highlighted. Especially helpful is the use of electrostatic potential surface models of reacting molecules. These maps emphasize, in an easily interpreted, color-coded fashion, how the majority of reactions involve areas of higher electron density on one reactant (a nucleophile) interacting with areas of lower electron density on the other reactant (an electrophile).

It is a graphical representation of the different organic reactions taught in the context of the important functional groups. The functional groups of an organic chemistry roadmap are analogous to cities on a real roadmap, and the reactions are like the roads between those cities. Arrows are used to represent known routes between functional groups, and the reagents required to bring about each reaction are written next to the corresponding arrow. Multistep synthesis questions are often very challenging for organic chemistry students even though synthesis is at the core of organic chemistry as a discipline. The power of the organic chemistry reaction roadmap is that it helps students visualize the reactions to interconvert key functional groups in multistep synthesis problems. The construction and use of organic chemistry reaction roadmaps are introduced in the end-of-chapter problems beginning in Chapter 6 and presented in complete form in a new Appendix 11, which students can tear out and use next to a problem. A FrESH Look AT orBITALS An organic chemist’s theoretical framework for understanding electron density within molecules is based on atomic and molecular orbitals. Paradoxically, organic chemistry texts generally provide only passing coverage of orbitals, never revealing their true shapes or full significance. The seventh edition paints a detailed picture of the orbital nature of electron density in Chapter 1 by focusing on the interplay between the two complementary approaches to orbital descriptions: valence bond theory and molecular orbital theory. Chapter 1 provides a comprehensive description of how organic chemists use electronic theory to understand structure, bonding, and reactivity. Significantly, students are given easy-to-use guidelines that detail when and how to use electronic theory, even in complex situations, such as molecules described by multiple resonance contributing structures. The inclusion of calculated orbital diagrams alongside the familiar orbital cartoons gives students a greater appreciation for orbital sizes and shapes that are reinforced throughout the book. The intent is to provide students with a strong theoretical foundation that will give them unprecedented insight and intuition into molecular structure and reactivity. A FrESH Look AT MCAT PrEPArATIon A significant number of students taking organic chemistry are doing so to prepare for standardized tests such as the MCAT, DAT, or PCAT. Often, organic chemistry content on the MCAT is in the form of passages followed by a series of multiple-choice questions. Learning to answer questions based on passages requires students to develop increased reading comprehension and analytical skills. The seventh edition of Organic Chemistry is the first text to aid students in developing these skills by introducing an extensive series of passages followed by several thoughtprovoking multiple-choice questions in almost every chapter (MCAT Practice: Passage and Questions). The passages cover interesting applications of organic chemistry principles as well as biological and chemical topics. Thus, far from being just test preparation, these passages add considerable enrichment to the material being presented. ROADMAP REACTION Copyright 2013 Cengage Learning. All Rights Reserved.

Unless otherwise noted all art on this page © Cengage Learning 2013 Preface xxv Organic chemistry applied tO the synthesis Of cOmplex mOlecules Organic chemistry enables the synthesis of thousands of useful molecules. Synthetic applications of the reactions covered in this text are emphasized throughout, partly through the many new challenging synthesis problems, the goal of which is to demonstrate to students how synthetic organic chemistry is used in pharmaceutical research and in the production of useful pharmaceuticals. The text provides applications of the reactions to the synthesis of important molecules, such as Valium, fluoxetine (Prozac), meperidine (Demerol), albuterol (Proventil), tamoxifen, and sildefanil (Viagra). Multistep synthesis problems challenge students to develop their own multistep synthetic plan for converting a relatively simple starting material into a more complex target molecule. Multistep synthesis is supported by an expanded description of retrosynthetic analysis in multiple chapters, including tips on recognizing when to use certain reactions, such as those involving enolates in the construction of complex structures. Organic chemistry applied tO BiOlOgy The application of organic chemistry principles to important biological molecules is integrated where appropriate to establish a bridge with biochemistry courses. In particular, Connections to Biological Chemistry gives special attention to those aspects of organic chemistry that are essential to understanding the chemistry of living systems. For example, the organic chemistry of amino acids is highlighted beginning in Section 3.8, along with the importance of alkene geometry to both membrane fluidity and nutrition. How hydrogen bonding is involved with drug-receptor interactions (Section 10.2) is discussed. Importantly, these Connections to Biological Chemistry features have been added throughout the book, not just at the end, because not all instructors make it through the biological chemistry chapters at the end of the text. Relevance to practical application is also emphasized in an expanded array of essays titled Chemical Connections. Topics include medicines such as penicillins and cephalosporins (MCAT Practice: Section 18.8), food supplements such as antioxidants (Section 8.7), and materials science concepts such as spider silk (Chemical Connections: Section 27.6). These sections provide a bridge between the theory of organic chemistry and well-known, current, practical applications. A list of the Chemical Connections as well as Connections to Biological Chemistry essays can be found on the inside back cover of this text. mastering skills Mastering organic chemistry requires the development of certain intellectual skills. To this end, 15 How To boxes highlight “survival skills” for organic chemistry students. Five new How To boxes to this edition are How To Quickly Figure Out Formal Charge, How To Quickly Recognize the Hybridization and Geometry of Atoms, How To Quickly Draw and Recognize Enantiomers and Diastereomers, How To Retrosynthetically Dissect an Amine into the Proper Starting Materials for a Reductive Amination, and How To Recognize Aromatic Compounds: Criteria and Caveats. helping students prepare mOre efficiently A key feature of the seventh edition is the end-of-chapter summaries, which are mini study guides designed to help students prepare for class exams and later for standardized tests such as the MCAT.

As a companion to the summary outlines, end-of-chapter summaries of key reactions systematically list the reactions covered in each chapter. These include prose descriptions of mechanisms as well as important information such as observed stereochemistry or regiochemistry. Students will find these reaction summaries particularly efficient when preparing for exam questions requiring application of reactions in the context of new molecules or even multistep syntheses. The appendix reference material has been enhanced with two unique items to provide students with a quickly accessible source of important information. The first is a thorough “Summary of Stereochemical Terms” (Appendix 8). Stereochemical terms are subtle and difficult to master, so having them compiled in one location allows students to compare and contrast any new terms with those learned in earlier chapters, as well as prepare for exams. In addition, Appendix 9, “Summary of the Rules of Nomenclature,” provides a practical listing of the nomenclature rules described throughout the text. In response to student requests, this appendix provides a single location for the rules students need when naming complex molecules that contain multiple functional groups. unIQuE orgAnIzATIonAL ELEMEnTS ● Together, Chapter 1 (comprehensive description of electronic theory) and Chapter 4 (detailed description of acids and bases in organic chemistry) provide a fundamental grasp of molecular structure and properties, giving students the basis to understand all aspects of the mechanistic discussions that follow. Equipping students with the proper tools from the beginning will give them a predictive command of reactivity and foster chemical intuition, while discouraging superficial memorization. ● Because of the increased use of NMR spectroscopy in chemical and biochemical research, as well as the growing dependence on MRI for medical diagnosis, Chapter 13, “Nuclear Magnetic Resonance Spectroscopy,” is detailed and up to date. The practical and theoretical aspects concerning NMR spectra and signal splitting patterns are highlighted, and a complete description of FT-NMR provides a stronger technical connection to MRI. ● Carbonyl chemistry (Chapters 16–19) is placed earlier than in most texts so that professors have time to teach this material to the majority of students in an organic chemistry class, who are geared toward a life science degree and/or career in the health professions. Carbonyl chemistry is fundamental to the chemistry of living systems, and connections between carbonyl chemistry and the chemistry of carbohydrates is highlighted earlier in the book. This latter change mirrors the increasing importance of carbohydrate chemistry on the MCAT. ● Chapter 24, “Catalytic Carbon-Carbon Bond Formation,” combines content from previous chapters and challenges students to devise syntheses. The intent is to expose students to the excitement and challenge of modern synthetic chemistry. WHAT’S nEW In this edition, we made major changes to provide a better theoretical understanding of organic chemistry as well as to provide better tools to prepare for exams. ● Two new primer sections were added to better prepare students to understand, as opposed to simply memorize, reaction mechanisms. The first, “Primer I: Reaction Mechanisms,” added prior to Chapter 6, introduces the concept of fundamental mechanistic elements and explains how to predict which mechanistic element is appropriate for a given step in the reaction mechanism being considered. This revolutionary approach promotes student understanding of the similarities and differences between different reactions, and perhaps more important, leads students to an intuitive understanding of how molecules react.

Unless otherwise noted all art on this page © Cengage Learning 2013 Preface xxvii ● “Primer II, Carboxylic Acid Derivative Reaction Mechanisms” was added just prior to Chapter 18, the chapter describing the reactions of carboxylic acid derivatives. This is a critical chapter for students because the reaction mechanisms of carboxylic acids have numerous steps with only subtle differences among them. Students who approach mechanisms by trying to memorize them generally do very poorly with this material. On the other hand, by reintroducing the unifying mechanistic element approach in front of this chapter, students are given the appropriate foundation to develop an intuitive understanding of carboxylic acid derivative mechanisms. ● Acknowledging that a significant number of students take organic chemistry courses as preparation for standardized exams such as the MCAT, this new edition is the first and only text on the market to contain MCAT-style passages and accompanying multiple-choice questions in almost every chapter. A significant portion of the organic chemistry section of the MCAT involves passages about intentionally new material that is related to concepts with which students should be familiar, followed by a series of multiple-choice questions intended to test students’ reading comprehension and analytical skills. These new passages not only introduce interesting applications of the material presented in the chapters but also provide students with the reading comprehension and analytical skills they need to do well in the organic chemistry passages sections of the MCAT exam. ● Organic chemistry reaction roadmaps were completely redrawn and highly refined in this edition. This innovation in organic chemistry learning gives students a visual representation of the different reactions and shows how these roadmaps can be used in specific sequences for the multistep synthesis of complex molecules. ● The description of several more modern synthetic methods were added, including the Swern, Dess-Martin, and Pinnick oxidations. SPECIAL FEATurES ● New A revolutionary new paradigm for learning organic chemistry mechanisms is introduced in “Primer I: Reaction Mechanisms” just prior to Chapter 6 and then used throughout the book. ● New The new mechanism paradigm for learning organic chemistry mechanisms is reviewed and applied to the mechanisms for carboxylic acid derivatives in a second all-new “Primer II, Carboxylic Acid Derivative Reaction Mechanisms” just prior to Chapter 18. ● New Several more modern synthetic methods were added, such as the Swern, Dess-Martin, and Pinnick oxidations. ● New MCAT Practice: Passage and Questions are incorporated into almost every chapter. These new passages and questions not only introduce interesting applications of the material presented in the chapters but also provide students with the reading comprehension and analytical skills they need to do well in the organic chemistry passages sections of the MCAT exam. ● Updated Organic Chemistry Reaction Roadmaps were completely redrawn to make them even more useful as an innovation in learning organic chemistry. Organic chemistry roadmaps are presented in end-of-chapter problems and in the newly designed Appendix 11 tear-out. ● Updated Accurate Orbital Diagrams were added throughout the text to provide students with a more realistic understanding of electronic theory as applied to organic chemistry. ● Updated Chemical Connections These essays illustrate applications of organic chemistry to everyday settings. Topics range from Chiral Drugs to Drugs That Lower Plasma Levels of Cholesterol and The Chemistry of Superglue. A complete list can be found on the inside back cover. Copyright 2013 Cengage Learning.

New essays include pyridoxine (vitamin B6) and electron transfer agents in biological oxidation-reduction reactions. ● Updated Fifteen How To features of key tools and topics are included. These describe “survival skills” for the organic chemistry student. Five How To boxes are new to this edition. ● Updated In-Chapter Examples There are an abundance of in-chapter examples, each with a detailed solution, so that students can immediately see how the concepts just discussed relate to specific questions and their answers. Following each inchapter example is a comparable in-chapter problem designed to give students the opportunity to solve a related problem on their own. ● Updated End-of-Chapter Summaries highlight, in outline form, all of the important ideas of the chapter. Each concept is keyed to the section in the chapter that provides a full explanation, as well as to the problems that reinforce understanding. ● Updated End-of-Chapter Summaries of Key Reactions list the reactions described in the chapter, complete with a prose description of the mechanism and important considerations such as stereochemistry and regiochemistry. ● Updated End-of-Chapter Problems There are plentiful end-of-chapter problems, with the majority categorized by topic. A red problem number indicates an applied, real-world problem. There are numerous multistep synthesis problems, many dealing with the synthesis of important pharmaceuticals, and Reactions in Context problems dealing with functional group transformations of more complex molecules. ● Updated Glossary of Key Terms Throughout the book, definitions for new terms are placed in the margin for easy reference. In addition, all definitions are collected in a handy glossary at the end of the text and keyed to the section where the term is introduced. ● Updated Precise Stereochemical Definitions are compiled in a unique appendix. A comprehensive listing of stereochemical terms in a single collection provides students with a resource they can refer to often as they encounter new terms. ● Updated A Unique Nomenclature Appendix This appendix provides a comprehensive listing of all the rules introduced in the text governing nomenclature of complex molecules. ● Updated A Unique Arrow Pushing Appendix In this appendix, the correct use of arrow pushing is emphasized and students are encouraged to avoid common mistakes. ● Updated Full-Color Art Program One of the most distinctive features of this text is its visual impact. The text’s extensive full-color art program includes a large number of molecular models generated with a three-dimensional look, as well as applied photos. In addition, special colors are used to highlight parts of molecules and to follow the course of reactions. ● Updated Electrostatic Potential Maps are provided at appropriate places throughout the text to illustrate the important concepts of resonance, electrophilicity, and nucleophilicity.

Besser Konzepte und Ideen der organischen Chemie verstehen, als eine Vielzahl von Fakten auswendig beherrschen! Diesem Motto bleibt der "Vollhardt/Schore" auch in der neuesten Auflage treu. Das neu gestaltete Layout, beispielhaft gelöste Übungsaufgaben und die deutlich erweiterten Verständnisübungen führen einprägsam an die Methodik zur Lösung organisch-chemischer Probleme heran. So werden nicht nur die stofflichen Grundlagen der organischen Chemie, sondern auch das "Gewusst wie" fast schon spielerisch vermittelt. Nicht nur für Chemiestudenten, auch für Biochemiker, Pharmazeuten, Biologen und Mediziner ist der "Vollhardt/Schore" der fachliche Grundstock für die organische Chemie.
