Organic chemistry is a core part of the chemistry curricula, and advanced levels texts often obscure the essential framework underlying and uniting the vast numbers of reactions as a result of the high level of detail presented. The material in this book is condensed into a manageable text of 350 pages and presented in a clear and logical fashion, focusing purely on the basics of the subject without going through exhaustive detail or repetitive examples. The book aims to bridge the gap between undergraduate organic chemistry textbooks and advanced level textbooks, beginning with a basic introductory course and arranging the reaction mechanisms according to an ascending order of difficulty. As such, the author believes the book will be excellent primer for advanced postgraduates Reaction Mechanisms in Organic Synthesis is written from the point of view of the synthetic organic chemist, enabling students and researchers to understand and expand on reactions covered in foundation courses, and to apply them in a practical context by designing syntheses. As a further aid to the practical research student, the content is organized according to the conditions under which a reaction is executed rather than by the types of mechanisms. Particular emphasis is placed on controlling stereospecificity and regiospecificity. Topics covered include: Transition metal mediated carbon-carbon bond formation reactions Use of stabilized carbanions, ylides and enamines for carbon-carbon bond formation reactions, Advanced level use of oxidation and reduction reagents in synthesis. As a modern text, this book stands out from its competitors due to its comprehensive coverage of recently published research. The book contains specific examples from the latest literature, covering modern reactions and the latest procedural modifications. The focus on contemporary and synthetically useful reactions ensures that the contents are specifically relevant and attractive to postgraduate students and industrial organic chemists.

Electrochemical reactions make significant contributions to organic synthesis either in the laboratory or on an industrial scale. These methods have the potential for developing more "green" chemical synthesis. Over recent years, modern investigations have clarified the mechanisms of important organic electrochemical reactions. Progress has also been made in controlling the reactivity of intermediates through either radical or ionic pathways. Now is the time to gather all the electrochemical work into a textbook. As an essential addition to the armory of synthetic organic chemists, electrochemical reactions give results not easily achieved by many other chemical routes. This book presents a logical development of reactions and mechanisms in organic electrochemistry at a level suited to research scientists and final year graduate students. It forms an excellent starting point from which synthetic organic chemists, in both academia and industry, can appreciate uses for electrochemical methods in their own work. The book is also a reference guide to the literature.

This English edition of a best-selling and award-winning German textbook Reaction Mechanisms: Organic Reactions · Stereochemistry · Modern Synthetic Methods is aimed at those who desire to learn organic chemistry through an approach that is facile to understand and easily committed to memory. Michael Harmata, Norman Rabjohn Distinguished Professor of Organic Chemistry (University of Missouri) surveyed the accuracy of the translation, made certain contributions, and above all adapted its rationalizations to those prevalent in the organic chemistry community in the English-speaking world. Throughout the book fundamental and advanced reaction mechanisms are presented with meticulous precision. The systematic use of red "electron-pushing arrows" allows students to follow each transformation elementary step by elementary step. Mechanisms are not only presented in the traditional contexts of rate laws and substituent effects but, whenever possible, are illustrated using practical, useful and state-of-the-art reactions. The abundance of stereoselective reactions included in the treatise makes the reader familiar with key concepts of stereochemistry. The fundamental topics of the book address the needs of upper-level undergraduate students, while its advanced sections are intended for graduate-level audiences. Accordingly, this book is an essential learning tool for students and a unique addition to the reference desk of practicing organic chemists, who as life-long learners desire to keep abreast of both fundamental and applied aspects of our science. In addition, it will well serve ambitious students in chemistry-related fields such as biochemistry, medicinal chemistry and pharmaceutical chemistry. From the reviews: "Professor Bruckner has further refined his already masterful synthetic organic chemistry classic; the additions are seamless and the text retains the magnificent clarity, rigour and precision which were the hallmark of previous editions. The strength of the book stems from Professor Bruckner’s ability to provide lucid explanations based on a deep understanding of physical organic chemistry and to limit discussion to very carefully selected reaction classes illuminated by exquisitely pertinent examples, often from the recent literature. The panoply of organic synthesis is analysed and dissected according to fundamental structural, orbital, kinetic and thermodynamic principles with an effortless coherence that yields great insight and never over-simplifies. The perfect source text for advanced Undergraduate and Masters/PhD students who want to understand, in depth, the art of synthesis ." Alan C. Spivey, Imperial College London "Bruckner’s ‘Organic Mechanisms’ accurately reflects the way practicing organic chemists think and speak about organic reactions. The figures are beautifully drawn and show the way organic chemists graphically depict reactions. It uses a combination of basic valence bond pictures with more sophisticated molecular orbital treatments. It handles mechanisms both from the "electron pushing perspective" and from a kinetic and energetic view. The book will be very useful to new US graduate students and will help bring them to the level of sophistication needed to be serious researchers in organic chemistry." Charles P. Casey, University of Wisconsin-Madison "This is an excellent advanced organic chemistry textbook that provides a key resource for students and teachers alike." Mark Rizzacasa, University of Melbourne, Australia.

A reactions oriented course is a staple of most graduate organic programs, and synthesis is taught either as a part of that course or as a special topic. Ideally, the incoming student is an organic major, who has a good working knowledge of basic reactions, stereochemistry and conformational principles. In fact, however, many (often most) of the students in a first year graduate level organic course have deficiencies in their undergraduate work, are not organic majors and are not synthetically inclined. To save students much time catching up this text provides a reliable and readily available source for background material that will enable all graduate students to reach the same high level of proficiency in organic chemistry. Produced over many years with extensive feedback from students taking an organic chemistry course this book provides a reaction based approach. The first two chapters provide an introduction to functional groups; these are followed by chapters reviewing basic organic transformations (e.g. oxidation, reduction). The book then looks at carbon-carbon bond formation reactions and ways to ‘disconnect’ a bigger molecule into simpler building blocks. Most chapters include an extensive list of questions to test the reader’s understanding. There is also a new chapter outlining full retrosynthetic analyses of complex molecules which highlights common problems made by scientists. The book is intended for graduate and postgraduate students, scientific researchers in chemistry New publisher, new edition; extensively updated and corrected Over 950 new references with more than 6100 references in total Over 600 new reactions and figures replaced or updated Over 300 new homework problems from the current literature to provide nearly 800 problems to test reader understanding of the key principles

Bridging the Gap Between Organic Chemistry Fundamentals and Advanced Synthesis Problems Introduction to Strategies of Organic Synthesis bridges the knowledge gap between sophomore-level organic chemistry and senior-level or graduate-level synthesis to help students more easily adjust to a synthetic chemistry mindset. Beginning with a thorough review of reagents, functional groups, and their reactions, this book prepares students to progress into advanced synthetic strategies. Major reactions are presented from a mechanistic perspective and then again from a synthetic chemist’s point of view to help students shift their thought patterns and teach them how to imagine the series of reactions needed to reach a desired target molecule. Success in organic synthesis requires not only familiarity with common reagents and functional group interconversions, but also a deep understanding of functional group behavior and reactivity. This book provides clear explanations of such reactivities and explicitly teaches students how to make logical disconnections of a target molecule. This new Second Edition of Introduction to Strategies for Organic Synthesis: Reviews fundamental organic chemistry concepts including functional group transformations, reagents, stereochemistry, and mechanisms Explores advanced topics including protective groups, synthetic equivalents, and transition-metal mediated coupling reactions Helps students envision forward reactions and backwards disconnections as a matter of routine Gives students confidence in performing retrosynthetic analyses of target molecules Includes fully-worked examples, literature-based problems, and over 450 chapter problems with detailed solutions Provides clear explanations in easy-to-follow, student-friendly language Focuses on the strategies of organic synthesis rather than a catalogue of reactions and modern reagents The prospect of organic synthesis can be daunting at the outset, but this book serves as a useful stepping stone to refresh existing knowledge of organic chemistry while introducing the general strategies of synthesis. Useful as both a textbook and a bench reference, this text provides value to graduate and advanced undergraduate students alike.

Intended for students of intermediate organic chemistry, this text shows how to write a reasonable mechanism for an organic chemical transformation. The discussion is organized by types of mechanisms and the conditions under which the reaction is executed, rather than by the overall reaction as is the case in most textbooks. Each chapter discusses common mechanistic pathways and suggests practical tips for drawing them. Worked problems are included in the discussion of each mechanism, and "common error alerts" are scattered throughout the text to warn readers about pitfalls and misconceptions that bedevil students. Each chapter is capped by a large problem set.

Organic Chemistry: Structure, Mechanism, Synthesis, Second Edition, provides basic principles of this fascinating and challenging science, which lies at the interface of physical and biological sciences. Offering accessible language and engaging examples and illustrations, this valuable introduction for the in-depth chemistry course engages students and gives future and new scientists a new approach to understanding, rather than merely memorizing the key concepts underpinning this fundamental area. The book builds in a logical way from chemical bonding to resulting molecular structures, to the corresponding physical, chemical and biological properties of those molecules. The book explores how molecular structure determines reaction mechanisms, from the smallest to the largest molecules—which in turn determine strategies for organic synthesis. The book then describes the synthetic principles which extend to every aspect of synthesis, from drug design to the methods cells employ to synthesize the molecules of which they are made. These relationships form a continuous narrative throughout the book, in which principles logically evolve from one to the next, from the simplest to the most complex examples, with abundant connections between the theory and applications. Featuring in-book solutions and instructor PowerPoint slides, this Second Edition offers an updated and improved option for students in the two-semester course and for scientists who require a high quality introduction or refresher in the subject. Offers improvements for the two-semester course sequence and valuable updates including two new chapters on lipids and nucleic acids Features biochemistry and biological examples highlighted throughout the book, making the information relevant and engaging to readers of all backgrounds and interests Includes a valuable and highly-praised chapter on organometallic chemistry not found in other standard references
