Asymmetric Organocatalysis: From Infancy to Adolescence

Angewandte Chemie - International Edition, 2008
AbstractAfter 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.

Cinchona Alkaloids in Asymmetric Organocatalysis [PDF]

Synthesis, 2010
This article reviews the applications of cinchona alkaloids as asymmetric catalysts. In the last few years, characterized by the resurgence of interest in asymmetric organocatalysis, cinchona derivatives have been shown to catalyze an outstanding array of chemical reactions, often with remarkable stereoselectivity. This work presents an overview of the
