Modern Methods In Stereoselective Aldol Reactions

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 third edition of this well-known textbook discusses some modern methods used in organic synthesis, and aims to show the value and scope of these methods and how they are used in the synthesis of complex molecules. The general plan of the book follows that of the second edition, but the opportunity has been taken to bring the book up to date and to take account of advances in knowledge and of new reactions which have come into use since publication of the earlier editions. Particular emphasis is placed on highly stereoselective organic chemistry, including stereoselective alkylations, aldol reactions, oxidations, epoxidations and reductions. New methods for the stereoselective formation of carbon-carbon double bonds, and modern application reactions are also fully considered. The book will be of use to students of chemistry and biochemistry at graduate and senior undergraduate level. It will also interest practising scientists in industry and research establishments who wish to familiarise themselves with modern synthetic methods.

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

Textbook on modern methods of organic synthesis.

At long last, the complete spectrum of the aldol reaction is presented here in this two-volume handbook. Top authors guarantee contributions of the highest quality, beginning with fundamentals and then moving on to enolates and catalytic aldol reactions, including the Mukaiyama Reaction. Further sections are devoted to enzymatic aldol reactions in synthesis as well as such related reactions as the Henry, Ene and Aldol-Tishchenko reactions. The wealth of information contained here allows a comprehensive overview of this important topic in organic chemistry, removing the need for the hitherto time-consuming research among the widely dispersed literature. With a foreword by Professor D. A. Evans.

Green Biocatalysis presents an exciting green technology that uses mild and safe processes with high regioselectivity and enantioselectivity. Bioprocesses are carried out under ambient temperature and atmospheric pressure in aqueous conditions that do not require any protection and deprotection steps to shorten the synthetic process, offering waste prevention and using renewable resources. Drawing on the knowledge of over 70 internationally renowned experts in the field of biotechnology, Green Biocatalysis discusses a variety of case studies with emphases on process R&D and scale-up of enzymatic processes to catalyze different types of reactions. Random and directed evolution under process conditions to generate novel highly stable and active enzymes is described at length. This book features: A comprehensive review of green bioprocesses and application of enzymes in preparation of key compounds for pharmaceutical, fine chemical, agrochemical, cosmetic, flavor, and fragrance industries using diverse enzymatic reactions Discussion of the development of efficient and stable novel biocatalysts under process conditions by random and directed evolution and their applications for the development of environmentally friendly, efficient, economical, and sustainable green processes to get desired products in high yields and enantiopurity The most recent technological advances in enzymatic and microbial transformations and cuttingedge topics such as directed evolution by gene shuffling and enzyme engineering to improve biocatalysts With over 3000 references and 800 figures, tables, equations, and drawings, Green Biocatalysis is an excellent resource for biochemists, organic chemists, medicinal chemists, chemical engineers, microbiologists, pharmaceutical chemists, and undergraduate and graduate students in the aforementioned disciplines.

An updated overview of the rapidly developing field of green techniques for organic synthesis and medicinal chemistry Green chemistry remains a high priority in modern organic synthesis and pharmaceutical R&D, with important environmental and economic implications. This book presents comprehensive coverage of green chemistry techniques for organic and medicinal chemistry applications, summarizing the available new technologies, analyzing each technique’s features and green chemistry characteristics, and providing examples to demonstrate applications for green organic synthesis and medicinal chemistry. The extensively revised edition of Green Techniques for Organic Synthesis and Medicinal Chemistry includes 7 entirely new chapters on topics including green chemistry and innovation, green chemistry metrics, green chemistry and biological drugs, and the business case for green chemistry in the generic pharmaceutical industry. It is divided into 4 parts. The first part introduces readers to the concepts of green chemistry and green engineering, global environmental regulations, green analytical chemistry, green solvents, and green chemistry metrics. The other three sections cover green catalysis, green synthetic techniques, and green techniques and strategies in the pharmaceutical industry. Includes more than 30% new and updated material—plus seven brand new chapters Edited by highly regarded experts in the field (Berkeley Cue is one of the fathers of Green Chemistry in Pharma) with backgrounds in academia and industry Brings together a team of international authors from academia, industry, government agencies, and consultancies (including John Warner, one of the founders of the field of Green Chemistry) Green Techniques for Organic Synthesis and Medicinal Chemistry, Second Edition is an essential resource on green chemistry technologies for academic researchers, R&D professionals, and students working in organic chemistry and medicinal chemistry.
