Kurzbeschreibung
This book presents a comprehensive overview of six-membered chair-like transition states in organic synthesis. Logically organized by reaction type, the sections focus on [3,3]-sigmatropic rearrangements, aldol reactions, metal allylation reactions, stereoselective reductions, and other reactions. Each reaction contains an introduction to the reaction type and history, a discussion of the corresponding six-membered chair-like transition state, and details of synthetic applications in natural products synthesis.
How stereoselective reactions occur through six-membered transition states
This book is a definitive guide for furthering readers' understanding of the amazing features of six-membered transition states in stereoselective organic reactions. Comprehensive and logically organized, it:
*
Covers reactions classified in four categories: [3,3]-sigmatropic rearrangements, aldol reactions, metal allylation reactions, and stereoselective reductions
*
Includes "General Considerations" for each category in which the author presents computational studies that support a proposal of a six-membered state
*
Provides a thorough discussion of each reaction category, including an introduction and history, a discussion of the corresponding six-membered transition state, and details of synthetic applications in natural product synthesis
*
Incorporates real-life applications of these transition states to the total syntheses of biologically active natural products
*
Covers literature up to 2006, with the original references cited for further study
This is a premier reference for organic chemists, medicinal chemists, and physical organic chemists and researchers in industries and institutes focusing on fine chemicals, including pharmaceuticals, agriculture/biotech, and polymers/materials. It is also an illuminating text for upper-level undergraduate and graduate students in organic chemistry. The author's primary goal is to assist professors, researchers, and students in proposing reasonable transition states for the description of newly discovered stereo-selective reactions.
