One approach to organic synthesis is retrosynthetic analysis. With this approach a chemist will start with the structure of their target molecule and progressively cut bonds to create simpler molecules. Reversing this process gives a synthetic route to the target molecule from simpler starting materials. This “disconnection” approach to synthesis is now a fundamental part of every organic synthesis course. Organic Synthesis: The Disconnection Approach, 2nd Edition introduces this important technique, to help students to design their own organic syntheses. There are forty chapters: those on the synthesis of given types of molecules alternate with strategy chapters in which the methods just learnt are placed in a wider context. The synthesis chapters cover many ways of making each type of molecule starting with simple aromatic and aliphatic compounds with one functional group and progressing to molecules with many functional groups. The strategy chapters cover questions of selectivity, protection, stereochemistry, and develop more advanced thinking via reagents specifically designed for difficult problems. Examples are drawn from pharmaceuticals, agrochemicals, natural products, pheromones, perfumery and flavouring compounds, dyestuffs, monomers, and intermediates used in more advanced synthetic work. Reasons for wishing to synthesise each compound are given. This second edition has been fully revised and updated with a modern look. Recent examples and techniques are included and illustrated additional material has been added to take the student to the level required by the sequel, “Organic Synthesis: Strategy and Control”. Several chapters contain extensive new material based on courses that the authors give to chemists in the pharmaceutical industry. Organic Synthesis: The Disconnection Approach, 2nd edition provides a full course in retrosynthetic analysis for chemistry and biochemistry students and a refresher for organic chemists working in industry and academia.

Reversing this process gives a synthetic route to the target molecule from simpler starting materials. This “disconnection” approach to synthesis is now a fundamental part of every organic synthesis course. Workbook for Organic Synthesis: The Disconnection Approach, 2nd Edition This workbook provides a comprehensive graded set of problems to illustrate and develop the themes of each of the chapters in the textbook Organic Synthesis: The Disconnection Approach, 2nd Edition. Each problem is followed by a fully explained solution and discussion. The examples extend the student’s experience of the types of molecules being synthesised by organic chemists, and the strategies they employ to control their syntheses. By working through these examples students will develop their skills in analysing synthetic challenges, and build a toolkit of strategies for planning new syntheses. Examples are drawn from pharmaceuticals, agrochemicals, natural products, pheromones, perfumery and flavouring compounds, dyestuffs, monomers, and intermediates used in more advanced synthetic work. Reasons for wishing to synthesise each compound are given. Together the workbook and textbook provide a complete course in retrosynthetic analysis.

Organic Synthesis: Strategy and Control is the long-awaited sequel to Stuart Warren’s bestseller Organic Synthesis: The Disconnection Approach, which looked at the planning behind the synthesis of compounds. This unique book now provides a comprehensive, practical account of the key concepts involved in synthesising compounds and focuses on putting the planning into practice. The two themes of the book are strategy and control: solving problems either by finding an alternative strategy or by controlling any established strategy to make it work. The book is divided into five sections that deal with selectivity, carbon-carbon single bonds, carbon-carbon double bonds, stereochemistry and functional group strategy. A comprehensive, practical account of the key concepts involved in synthesising compounds Takes a mechanistic approach, which explains reactions and gives guidelines on how reactions might behave in different situations Focuses on reactions that really work rather than those with limited application Contains extensive, up-to-date references in each chapter Students and professional chemists familiar with Organic Synthesis: The Disconnection Approach will enjoy the leap into a book designed for chemists at the coalface of organic synthesis.

Das explosionsartige Anwachsen des chemischen Wissens hat in den letzten Jahrzehnten im Bereich der organischen Chemie zu einer schier unübersehbaren Anzahl neuer und neuartiger Verbindungen und Verbindungsklassen geführt, deren rationelle Benennung immer größere Schwierigkeiten bereitete. Ursprünglich war ja die Namensgebung eines neuen Stoffes weitgehend, wenn nicht völlig in das Belieben des Entdeckers gestellt, der den Namen häufig von einer direkten sinnlichen Wahrnehmung ableitete oder sich gar ganz von der Intuition leiten ließ. Da die mehr oder weniger willkürlich gebildeten "Trivialnamen" meist gar nichts über die Strukturen der Verbindungen aussagten, konnten sie auch in keinen sinnvollen Zusammenhang zueinander ge bracht werden. Mit dem zunehmenden Verständnis der strukturellen Beziehungen der Organischen Chemie wuchs aber die Tendenz, eine allgemeinverbindliche und systema tische Nomenklatur zu entwickeln, die es erlauben sollte, wesentliche konstitutionelle Aussagen über ein Molekül be reits aus dessen Namen abzuleiten. Andererseits wollte man einen großen Teil der althergebrachten Trivial- und Semi trivialnamen nicht so ohne weiteres aufgeben. Dennoch ist es den damit befaßten Instanzen der "International Union of Pure and Applied Chemistry", der IUPAC, gelungen, ein einheitliches und ausbaufähiges Nomen klatursystem zu entwickeln, das mittlerweile allgemein und international anerkannt ist. Die Originalfassung der IUPAC Nomenklaturregeln der Organischen Chemie ist ein unver zichtbares Hilfsmittel für den Spezialisten. Als Einführung in die Materie ist jedoch eine knappere und präzisere "Ge brauchsanweisung" eher am Platze, die an Hand zahlreicher, sorgfältig ausgewählter bzw. konstruierter Beispiele die Geltungsbereiche der einzelnen Regeln möglichst voll ständig überstreicht.

This book connects a retrosynthetic or disconnection approach with synthetic methods in the preparation of target molecules from simple, achiral ones to complex, chiral structures in the optically pure form. Retrosynthetic considerations and asymmetric syntheses are presented as closely related topics, often in the same chapter, underlining the importance of retrosynthetic consideration of target molecules neglecting stereochemistry and equipping readers to overcome the difficulties they may encounter in the planning and experimental implementation of asymmetric syntheses. This approach prepares students in advanced organic chemistry courses, and in particular young scientists working at academic and industrial laboratories, for independently solving synthetic problems and creating proposals for the synthesis of complex structures.

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

Contrary to all other books in the field of organic synthesis, this volume combines Corey's methodology, which is based on the concept of synthon and retrosynthetic analysis, with Evans' methodology based on the `Lapworth model' of alternating polarities. Using this approach, the formation of carbon-carbon bonds and the manipulation of functional groups are treated together, whereas the stereochemical aspects are considered separately. Emphasis is laid on the importance of rigid structures, whether in the starting materials, the synthetic intermediates or the transition states, as a means of controlling the stereochemistry of the organic compounds. Enclosed with the book is a copy of a miniprogram (CHAOS) for an IBM PC, or fully compatible computers, which is an interactive program, affording the beginner a fast and easy way of learning, exploring and looking for new synthetic schemes of molecules of moderate complexity. As a textbook on organic synthesis, this volume will be of immense value at university level.

Teaches and enables students to build confidence in drawing and manipulating curly arrows, a fundamental skill for all organic chemists This book is an interactive approach to learning about chemistry of the carbonyl group—inviting students to work through its pages with pencil and paper in hand. It educates with the belief that the most effective way to learn is by practice and interaction. With this in mind, the reader is asked to predict what would happen under a specific set of reaction conditions. The book is divided into frames: each frame poses a question and invites the reader to predict what will happen. Subsequent frames give the solution but then pose more questions to develop a theme further. Chemistry of the Carbonyl Group: A Programmed Approach to Organic Reaction Mechanisms, Revised Edition provides a solid grounding in the fundamental reactions of carbonyls. Presented in full colour to enhance the understanding of mechanisms within chemistry, the chapters of this step-by-step guide cover: nucleophilic addition to the carbonyl group; nucleophilic substitution; nucleophilic substitution at the carbonyl group with complete removal of carbonyl oxygen; carbanions and enolisation; and building organic molecules from carbonyl compounds. A must-have book for undergraduate chemists to emphasise understanding in carbonyl group chemistry Goes through all the stages of basic carbonyl chemistry, detailing even the simplest mechanisms A step-by-step learning guide to synthetic chemistry for the first year of a chemistry degree, with all the information needed for independent learning Provides a solid grounding in the fundamental reactions of carbonyls which will inform the understanding of many other organic chemistry reactions Chemistry of the Carbonyl Group: A Programmed Approach to Organic Reaction Mechanisms - Revised Edition is packed with all the information on synthetic chemistry that every first-year student will need in order to learn independently.
