Selectivity is an important part of organic synthesis. The whole basis of organic chemistry, and especially organic synthesis, depends upon the selectivity which can be achieved in organic reactions. This concise textbook describes the strategies which can be adopted to improve selectivity, and the reactions which have been specially designed to afford high selectivity. The book illustrates the range of processes to which these principles can be applied and the high degree of selectivity which can be achieved. Selectivity in Organic Synthesis provides a solid introduction to this subject, focusing on the key areas and applications. Selectivity in Organic Synthesis features: * A concise introduction to selectivity in organic chemistry. * Lucidly written text including many carefully chosen examples and applications. * Numerous problems along with their solutions to help and encourage the reader. Suitable for organic chemistry students taking a course on organic synthesis or asymmetric synthesis in the 3rd or final year of an undergraduate chemistry course or in the first year of a postgraduate course.

Bringing together examples that until now were often hidden and widely spread throughout the original literature, this textbook shows how to use the correct reagents, conditions or reaction sequences to have access to all possible stereoisomers when beginning synthesis with only a single starting material. Adopting a didactic approach, the authors have chosen general and simple examples throughout the book so that these reactions can be transferred easily to other reaction types. While of major interest to master and PhD students alike, this book is also a source of valuable information for organic chemists in both academia and industry.

The demand for selective organic reactions is growing more acute everyday. Indeed, greater product selectivity has an important impact on energy and resource utilization, in terms of reduced process energy requirements for product separation and purification, in terms of low-value by-products, and in terms of environmental acceptance and compatibility. Moreover, more and more chemicals, especially pharmaceuticals, have to be sold in an optically active form. The search for selectivity constitutes a tremendous challenge for the chemists. In the last two decades, homogeneous transition metal based catalysis has emerged as one of the most promising tools for obtaining selectivity. In connection with developments in this area, this book contains updated and expanded versions of most of the lectures presented at a Cornett course held in Trieste (Italy) in 1989 and sponsored by the European Community. A primary aim is to cultivate a deeper understanding of the parameters that govern the selectivities and stimulate a wider utilization of transition metal based catalysis in organic synthesis. All aspects of selectivity, chemo-, regio-, stereo- and enantioselectivity are considered and illustrated by applications in various fields or organic synthesis. The impact of catalysis in oxydation, reduction, carbonylation reactions, carbene chemistry, in Ni and Pd promoted dimerizations, oligomerizations as well as fonctionalisations is stressed, quite often with special emphasis laid on reaction mechanisms. In this aspect, the last chapter examplifies the interest of high pressure NMR and IR when investigating the nature of reaction intermediates in homogeneous reactions.

Volume 4 focuses on additions and the resulting substitutions at carbon-carbon &pgr;-bonds. Part 1 includes processes generally considered as simple polar reactions, reactive electrophiles and nucleophiles adding to alkenes and alkynes. A major topic is Michael-type addition to electron deficient &pgr;-bonds, featured in the first six chapters. In part 2 are collected the four general processes leading to nucleophilic aromatic substitution, including radical chain processes and transition metal activation through to &pgr;-complexation. Metal-activated addition (generally by nucleophiles) to alkenes and polyenes is presented in part 3, including allylic alkylation catalyzed by palladium. The coverage of nonpolar additions in part 4 includes radical additions, organometal addition (Heck reaction), carbene addition, and 1,3-dipolar cycloadditions.

Volume 2 deals mainly with the addition reactions of delocalized carbanions (enolates) and their synthetic relatives (metalloenamines, enol ethers, allyl organometallics) with carbonyl compounds, imines and iminium ions. Major emphasis is placed on C-C bond-forming reactions such as the aldol and Mannich reactions. Acylation reactions are also included in this volume. Several topics that have not previously been reviewed are covered, including the use of enzymatic aldol reactions in synthesis and the Passerini-Ugi reactions.

This volume covers all methods of oxidation for use in organic synthesis. Emphasis has been placed on selectivity and functional group compatibility together with practical utility and applications. The volume is broadly divided to cover oxidation of unactivated carbon-hydrogen bonds, oxidation of activated carbon-hydrogen bonds, that is to say those adjacent to activating substituents and adjacent to heteroatoms, and oxidation of carbon-carbon double bonds. The volume also covers oxidation of C-X bonds, carbon-carbon single bonds, heteroatom oxidation and a number of special topics such as electrochemical methods, oxidative rearrangements, solid supported reagents, electron transfer oxidation, and biological methods.
