Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation and cross-coupling. Its phosphine and oxazoline groups coordinate effectively with metals like palladium, rhodium, and ruthenium, enabling high enantioselectivity in the synthesis of optically active compounds. Commonly applied in pharmaceutical and fine chemical industries for producing chiral intermediates. The (S)-configuration ensures specific stereochemical outcomes, making it valuable in the development of enantiopure drugs and agrochemicals.
