Best Synthetic Methods: Acetylenes, Allenes and Cumulenes

最佳合成方法：乙炔，丙二烯和异丙苯

ISBN：9780121257514，出版年：2003，中图分类号：O6

There is a vast and often bewildering array of synthetic methods and reagents available to organic chemists today. The Best Synthetic Methods series allows any scientist who is interested in the chemical transformations of molecules to choose between all the alternatives and assess their real advantages and limitations. With the emphasis on laboratory use, these volumes represent a comprehensive and practical guide to modern synthetic organic chemistry. Best Synthetic Methods: Acetylenes, Allenes and Cumulenes is the product of the author's many years practical experience and reading of the original literature. It contains a valuable distillation and critical evaluation of the Best Synthetic Methods for the formation and reaction of molecules containing carbon-carbon triple bonds or cumulative carbon-carbon double bonds. A brief review of each area is provided, but the emphasis in all cases is on describing efficient practical methods to effect the transformations described. The reader can therefore use this book to rapidly review and select the best methods of performing a synthetic conversion to create or modify a molecule containing an acetylene, allene or cumulene functionality. In addition, the documentation of a large number of experimental recipes enables the user to synthesise an unsaturated molecule without the need to access to the original literature.Reviews and evaluates the various methods for the formation and reaction of acetylenes, cumulenes and allenesProvides detailed practical experimental for many important reactionsGeneral tips and analytical data are provided from the author's own extensive research in this area

Synthesis of Naturally Occurring Nitrogen Heterocycles from Carbohydrates

由碳水化合物合成天然存在的氮杂环

Carbohydrates are widely distributed in nature and widely available, and so are considered as a promising feedstock for the preparation of many organic chemical compounds. They are particularly useful in the preparation of nitrogen heterocycles because of their related structural characteristics and easy availability. Synthesis of Naturally Occurring Nitrogen Heterocycles from Carbohydrates will review the recent literature dealing with use of carbohydrates as raw materials in the synthesis of these materials. The text contains six chapters arranged according to the complexity of the heterocyclic compounds discussed, ranging from five to seven membered rings and from single to multiple fused rings. The book provides a detailed discussion of the various synthetic approaches to these compounds, using carbohydrate starting materials, and does not merely reference synthetic methodology but attempts to give as much detail as possible on the actual experimental conditions used, in such a way that the chemist can use the information directly to design a multi-step synthesis. It discusses the different approaches to the synthesis of a wide range of naturally occurring nitrogen heterocycles in a format that enables the reader to make comparisons and decisions on whether to use a certain procedure, to modify it, or to devise a new synthetic methodology.
