Book Synopsis Copper-Catalyzed Asymmetric Synthesis by : Alexandre Alexakis

Download or read book Copper-Catalyzed Asymmetric Synthesis written by Alexandre Alexakis. This book was released on 2013-12-30. Available in PDF, EPUB and Kindle. Book excerpt: This book reflects the increasing interest among the chemical synthetic community in the area of asymmetric copper-catalyzed reactions, and introduces readers to the latest, most significant developments in the field. The contents are organized according to reaction type and cover mechanistic and spectroscopic aspects as well as applications in the synthesis of natural products. A whole chapter is devoted to understanding how primary organometallics interact with copper to provide selective catalysts for allylic substitution and conjugate addition, both of which are treated in separate chapters. Another is devoted to the variety of substrates and experimental protocols, while an entire chapter covers the use on non-carbon nucleophiles. Other chapters deal with less-known reactions, such as carbometallation or the additions to imines and related systems, while the more established reactions cyclopropanation and aziridination as well as the use of copper (II) Lewis acids are warranted their own special chapters. Two further chapters concern the processes involved, as determined by mechanistic studies. Finally, a whole chapter is devoted to the synthetic applications. This is essential reading for researchers at academic institutions and professionals at pharmaceutical or agrochemical companies.

Book Synopsis Catalysis in Asymmetric Synthesis by : Vittorio Caprio

Download or read book Catalysis in Asymmetric Synthesis written by Vittorio Caprio. This book was released on 2009-03-09. Available in PDF, EPUB and Kindle. Book excerpt: Asymmetric synthesis has become a major aspect of modern organic chemistry. The stereochemical properties of an organic compound are often essential to its bioactivity, and the need for stereochemically pure pharmaceutical products is a key example of the importance of stereochemical control in organic synthesis. However, achieving high levels of stereoselectivity in the synthesis of complex natural products represents a considerable intellectual and practical challenge for chemists. Written from a synthetic organic chemistry perspective, this text provides a practical overview of the field, illustrating a wide range of transformations that can be achieved. The book captures the latest advances in asymmetric catalysis with emphasis placed on non-enzymatic methods. Topics covered include: Reduction of alkenes, ketones and imines Nucleophilic addition to carbonyl compounds Catalytic carbon-carbon bond forming reactions Catalytic reactions involving metal carbenoids Conjugate addition reactions Catalysis in Asymmetric Synthesis bridges the gap between undergraduate and advanced level textbooks and provides a convenient point of entry to the primary literature for the experienced synthetic organic chemist.

Book Synopsis Improved Synthesis and Application of Planar-chiral Nucleophilic Catalysts in Asymmetric Reactions and Copper-catalyzed Enantioselective N-H Insertion Reactions by : Elaine C. Lee

Download or read book Improved Synthesis and Application of Planar-chiral Nucleophilic Catalysts in Asymmetric Reactions and Copper-catalyzed Enantioselective N-H Insertion Reactions written by Elaine C. Lee. This book was released on 2007. Available in PDF, EPUB and Kindle. Book excerpt: The development of an improved synthesis of nucleophilic planar-chiral catalysts is described in Chapter 1. This route is amenable to scale-up and preparative chiral HPLC is unnecessary to resolve the racemic catalysts. Using planar-chiral catalysts, two synthetic methodology projects have been developed: Chapter 2 describes the first asymmetric synthesis of trans P-lactams, and Chapter 3 describes the asymmetric synthesis of tertiary a-chloroesters. In the chapter describing the asymmetric synthesis of trans [beta]-lactams, we present mechanistic data supporting a novel mechanism, in which the N-triflylimine, rather than the ketene, reacts with the catalyst first. In the chapter describing the asymmetric synthesis of tertiary a-chloroesters, we introduced an under-utilized commercially available chlorinating reagent (2,2,6,6-tetrachlorocyclohexanone). Finally, in chapter 4, the Cu-catalyzed asymmetric synthesis of [alpha]-aminoesters via an N-H insertion is described. We have demonstrated that carbamates such as BocNH2 and CbzNH2 are efficient coupling partners in reactions with a-diazoesters to generate highly useful Boc- or Cbz-protected a-aminoesters.
