Stereo-Differentiating Reactions: The Nature of Asymmetric Reactions provides an introduction to asymmetric reactions. It brings together synthetic organic chemistry, stereochemistry, group theory, the theory of optical rotation, experimental methods, etc., all of which are basic to the study of stereo-differentiating reactions, to form a unified approach based on the new concept of "differentiation." The authors hope that the value of the new concept, which is rather more complex than conventional treatments of asymmetric reactions, will become clear in the present book. This new concept should be useful in many fields of study, not only the development of stereo-differentiating reactions, but also in the study of general reaction mechanisms in organic chemistry. The book contains nine chapters and begins with a historical background of studies on asymmetric reactions. This is followed by separate chapters on molecular symmetry and chirality; nomenclature for chirality, prochirality, and stereo-differentiating reactions; the mechanisms of stereo-differentiating reactions; methods for studying stereo-differentiating reactions; and the basic principle of optical activity.

The selective formation of bondings between molecules is one of the major challenges in organic chemistry, and the so-called aldol reaction is one of the most important for this purpose. These reactions are a highly useful tool for developing such novel substances as natural products and pharmaceuticals. Likes its highly successful and much appreciated predecessor, "Modern Aldol Reactions", this ready reference provides a systematic overview of methodologies for installing a required configuration during an aldol addition step, but shifts the focus so as to cover the latest developments. As such, it presents a set of brand new tools, including vinylogous Mukaiyama-aldol reactions and substrate-controlled aldol reactions, as well as asymmetric induction in aldol additions. Furthermore, new developments in existing stereoselective aldol additions are described, such as the deployment of supersilyl groups or organocatalyzed aldol additions. All of these methodologies are presented in the context of their deployment in the total synthesis of natural products.

The state-of-the-art in stereoselective synthesis! Thoroughly revised and updated, this enlarged second edition offers a plethora of valuable information on methods and reagents in stereoselective synthesis. Methods have been selected for high efficiency and selectivity; mechanistic aspects are treated succinctly, with a strong emphasis on practical applications. For this new edition, material has been added on * homogeneous diastereoselective hydrogenations * enantioselective oxidations * novel, efficient chiral auxiliaries Much of the information given is presented in figures and tables, which makes the book a valuable reference work for the practically minded organic chemist. From reviews of the first edition: 'The extensive material in the volume should prove particularly useful to anyone involved in synthetic chemistry or teaching a course in organic chemistry.' Journal of Medicinal Chemistry 'With nearly 1400 references cited, the book contains a wealth of information and should be a useful addition to the chemist's library.' The American Scientist

Synthesis of Azetidines from Imines by Cycloaddition Reactions presents several methodologies for the synthesis of azetidines from imines by cycloaddition reactions. The azetidines, known as important contribution of science to humanity, are important organic compounds that have occupied a basic position in the pharmaceutical chemistry for over a hundred years because of their biological activities. They are the fundamental skeleton of several antibiotics, probiotics and alkaloids. The synthesis of azetidines is a constant challenge for medicinal chemists, hence this book comprehensively describes azetidine ring synthesis. With this book, readers will be able to quickly assess possible synthetic approaches and evaluate whether preparation of a four-membered nitrogen containing ring is reasonable. - Highlights cycloaddition reactions of imines - Covers the synthesis of azetidines
