Abstract

Cinchona alkaloids and their derivatives can catalyze an amazing array of synthetically important reactions, providing access to chiral products of high enantiopurity. A review of such asymmetric reactions, comprising the work reported in the last two decades, is presented here. Cinchona alkaloids-derived catalysts and ligands, either in monomeric form or attached to a polymeric support, are included in this review.
