Since the original idea was explored by James in 1976, the use of chiral sulfoxides as ligands with transition metals in asymmetric catalysis has undergone a long period of development. There have been many studies into their properties, design and application in various kinds of asymmetric transformations. In this article, we document the literatures on chiral sulfoxide ligands in asymmetric catalytic reactions.
Keywords: Asymmetric catalysis; Chiral sulfoxide ligands; S-chirality; Transition-metal.
