Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling reactions. Its phosphine and oxazoline functional groups coordinate effectively with metals like palladium, rhodium, and ruthenium, enabling high enantioselectivity in the synthesis of chiral molecules. Widely applied in pharmaceutical and fine chemical industries for producing enantiomerically pure compounds. The tert-butyl and trifluoromethyl groups enhance steric bulk and electron-withdrawing properties, improving catalytic efficiency and selectivity.
