Asymmetric Organocatalysis: From Infancy to Adolescence
Angewandte Chemie International Edition, 2008AbstractAfter an initial period of validating asymmetric organocatalysis by using a wide range of important model reactions that constitute the essential tools of organic synthesis, the time has now been reached when organocatalysis can be used to address specific issues and solve pending problems of stereochemical relevance.

Asymmetric Supramolecular Organocatalysis: A Complementary Upgrade to Organocatalysis
European Journal of Organic Chemistry, 2017The recent past has witnessed tremendous growth in the field of asymmetric synthesis through “asymmetric supramolecular organocatalysis (ASO)”. ASO emerges from many interactions between substrates and catalysts: namely substrate–catalyst, catalyst–catalyst and substrate–substrate interactions.

Chiral Brønsted Acids for Asymmetric Organocatalysis
2009Chiral Brønsted acid catalysis is an emerging area of organocatalysis. Since the pioneering studies of the groups of Akiyama and Terada in 2004 on the use of chiral BINOL phosphates as powerful Brønsted acid catalysts in asymmetric Mannich-type reactions, numerous catalytic asymmetric transformations involving imine activation have been realized by ...

A Chiral Solvent Effect in Asymmetric Organocatalysis
Organic Letters, 2010Proline-catalyzed aldol reactions between enolizable ketones and aromatic aldehydes can be carried out in propylene carbonate. When enantiomerically pure propylene carbonate is used, the combination of (R)-proline and (R)-propylene carbonate constitutes a matched pair, while (S)-proline and (R)-propylene carbonate constitutes a mismatched pair.
