Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective transformations such as hydrogenation, allylic alkylation, and Diels-Alder reactions. Its rigid binaphthyl backbone and oxazoline rings provide excellent stereocontrol, making it effective in promoting high enantioselectivity. Commonly employed with transition metals like palladium, rhodium, or copper to form catalytically active complexes. Valued in pharmaceutical synthesis for constructing chiral centers with high optical purity.
