This book was released on 2002-01-04 with total page 1423 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Compendium is a detailed compilation of chiral auxiliaries which are used in the field of organic chemistry to direct "asymmetric synthesis". A molecule is called chiral because it can have two "enantiomers" -- like left and right-handed molecules. An enantiomer is either of two molecules of the same chemical composition that are mirror images of each other but not identical. A "chiral auxiliary" is an aid / auxiliary used to specifically produce either the left or right enantiomer of the chosen molecule, as desired. In this comprehesive reference source, industrial chemists can make informed selections of an auxiliary for a specific application. It is fully cross-referenced to enable the comparative selection of auxiliaries. The work includes over 13,000 auxiliary reaction applications with complete reaction details of the synthetic routes, reagents, and primary literature references. Key Features * This remarkable major reference work is the first such compilation and represents the only total source for the diverse applications of auxiliaries * Thoroughly cross-referenced to enable comparative

Available in PDF, EPUB and Kindle. Book excerpt: Chiral Building Blocks in Asymmetric Synthesis A comprehensive introduction to the important classes of chiral building blocks Chirality — the asymmetric quality found in certain chemical compounds — plays an essential role in our world: chiral compounds can be found in biology, pharmaceutical compounds, agrochemicals, and fragrances. The stereoselective preparation of these complex molecular constructions constitutes a challenge. To this end, modern asymmetric synthesis utilizes a variety of valuable and efficient reagents employed as chiral auxiliaries, metal complexes and organocatalysts in stereoselective catalysis, and enantiopure reactants termed as chiral building blocks. In Chiral Building Blocks in Asymmetric Synthesis, the achievements in the fields of preparation of and applications of chiral blocks are presented. In doing so, the book comprehensively discusses the important classes of these reactants as the key for the asymmetric synthesis of chiral molecules. As such, it is an indispensable resource about synthetic methods, as well as possible modifications and transformations of important classes of chiral compounds. It also highlights the importance of their use as reactants and auxiliaries in the preparation of more sophisticated molecules or supramolecular systems. In Chiral Building Blocks in Asymmetric Synthesis readers will also find: Organization according to the most important compound classes — e.g. amino acids, BINOL and its derivatives, terpenes, and others — with an emphasis on synthesis and application A focus on the use of chiral building blocks for the preparation of bioactive compounds and supramolecular assemblies Chiral Building Blocks in Asymmetric Synthesis is a useful reference for organic chemists, catalytic chemists, chemists in industry, medicinal chemists, pharmaceutical chemists, and the libraries that support them.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a timely go-to resource for any professionals wishing to communicate with the growing number of readers whose first language is not English. It highlights the potential language difficulties these readers face, and provides guidelines and tools for overcoming them. The guidelines show how to convey complicated information clearly without affecting the integrity of the subject matter, while the practical ‘before’ and ‘after’ examples clearly illustrate how using these guidelines and improves scientific texts. The book also includes text evaluation tools that allow writers to rapidly assess the readability of their materials. It is based on theory and the authors’ extensive experience in producing highly readable English texts for L2 readers who struggle with materials that were originally prepared for L1 readers.
