Description

This first comprehensive presentation of this hot and important topic compiles the most up-to-date methods for chiral amine synthesis. The international list of authors reads like a "Who's Who" of the subject, providing a large array of highly practical information concentrated into the useful and essential methods.
Following an introductory chapter devoted to helping readers quickly determine which strategies to choose for their investigation, this handbook and ready reference focuses on the examination of methods that are reliable and simultaneously efficient for the synthesis of structurally diverse aliphatic and aromatic chiral amines. Modern methods and applications found in (pharmaceutical) industry are also covered.
