Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling reactions. Its phosphine-oxazoline structure provides excellent stereocontrol, making it valuable in the synthesis of enantiomerically pure pharmaceuticals and fine chemicals. The ligand coordinates effectively with metals like palladium, rhodium, and iridium, enhancing catalytic activity and enantioselectivity. Commonly applied in the preparation of chiral intermediates for drugs and biologically active compounds.
