Applications of Planar-Chiral Heterocycles as Ligands in Asymmetric Catalysis

A new family of ligands for asymmetric transition metal-catalyzed reactions has been designed and synthesized. Thus, planar-chiral heterocycles furnish high enantioselectivity in a variety of processes, including isomerizations of allylic alcohols, O-H insertions, and 1,3-dipolar cycloadditions.
