Stereodivergence in Asymmetric Catalysis
Journal of the American Chemical Society, 2017This Perspective presents an overview of catalytic enantioselective transformations that allow convenient access to all stereoisomers of a given product with multiple stereogenic centers. Particular focus is placed on discussion of the concept of stereodivergent dual catalysis and its application in target-oriented synthesis.

The catalysis by primary and secondary amines of electrophilic substitution reactions in the α-position of carbonyl compounds and related reactions via enamine intermediates is called enamine catalysis. To a large degree this chemistry can be considered the catalytic variant of the classical preformed enamine chemistry (Scheme 1) pioneered by Stork. In

Asymmetric catalysis with peptides
Chemical Communications, 2011Over the past decade several peptides have been developed as effective asymmetric catalysts for a range of synthetically useful reactions. Many have properties that are difficult to achieve with other catalysts. The article highlights features that render peptidic organocatalysts unique and attractive for future applications.

Heterogeneous asymmetric catalysis
Pure and Applied Chemistry, 2004Abstract Examples of enantioselective catalysts, including homogeneous supported catalysts and biphasic liquid/liquid, are described and compared. In the case of asymmetric hydride transfer, polythiourea was proven to be more efficient for ruthenium-catalyzed reduction of arylketones, although the iridium complexes gave rise to higher ee

Nonlinear Effects in Asymmetric Catalysis
Angewandte Chemie International Edition, 2008AbstractThere is a need for the preparation of enantiomerically pure compounds for various applications. An efficient approach to achieve this goal is asymmetric catalysis. The chiral catalyst is usually prepared from a chiral auxiliary, which itself is derived from a natural product or by resolution of a racemic precursor.

Multifunctional Asymmetric Catalysis
2000The development of catalytic asymmetric reactions is one of the major areas of research in the field of organic chemistry. So far, a number of chiral catalysts have been reported, and some of them have exhibited a much higher catalytic efficiency than enzymes, which are natural catalysts (Herrmann and Cornils 1996; Noyori 1994; Ojima 1994; Bosnich 1986;

Additive Effects on Asymmetric Catalysis
Chemical Reviews, 2016This review highlights a number of additives that can be used to make asymmetric reactions perfect. Without changing other reaction conditions, simply adding additives can lead to improved asymmetric catalysis, such as reduced reaction time, improved yield, or/and increased selectivity.
