Abstract

Ligands useful for transition metal catalyzed bond forming reactions are provided with a metal binding portion having at least one metal binding moiety (I), wherein Ar and Ar' each is an aryl or a heteroaryl. These ligands may be prepared by providing an aromatic carboxylic acid having a diarylphosphino or diheteroarylphosphino substituent on the aromatic ring, and forming an ester or an amide derivative of the carboxylic acid by coupling with a chiral diol or a chiral diamine. The ligands facilitate flexible strategies for enantiocontrolled construction of five membered carbocyclic rings with varying substitution patterns and high enantioselectivity.
