Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Lewis Acids and Selectivity in Organic Synthesis written by M. Santelli and published by CRC Press. This book was released on 1995-11-21 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lewis acids provide inexpensive access to elaborated molecules obtained with high selectivities (regio-, stereo-, and enantioselectivity). Lewis Acids and Selectivity in Organic Synthesis is the first book to deal with these new and promising roles of Lewis acids. The book begins with general considerations on Lewis acids and a description of Lewis acid-carbonyl complexes, which are involved in most of the reactions described: ene reactions, allylsilane and allyltin addition to carbonyl compounds, addition of nucleophiles to acetals, conjugated addition of allylsilanes and allyltins to unsaturated carbonyl compounds (Sakurai reaction), and Diels-Alder reaction. Subsequent chapters examine these issue in detail, with special attention given to the way Lewis acids induce diastereo- and enantioselectivity. The extensive use of schemes (approximately 1000) ensures rapid visual uptake of the information. Lewis Acids and Selectivity in Organic Synthesis serves as a valuable source of information for all who face the challenge of selectivity in organic synthesis.

Download or read book Directed Selectivity in Organic Synthesis written by Tanja Gaich and published by John Wiley & Sons. This book was released on 2014-01-21 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Metal Promoted Selectivity in Organic Synthesis written by A. Noels and published by Springer. This book was released on 2012-09-24 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
