Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions. It plays a key role in enantioselective transformations such as hydrogenation and cross-coupling reactions, where high stereochemical control is required. Its phosphine and oxazoline functional groups coordinate effectively with metals like palladium, rhodium, and ruthenium, enhancing catalytic activity and selectivity. Commonly applied in the synthesis of pharmaceutical intermediates and fine chemicals where precise chirality is critical.
