Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation and cross-coupling. Its phosphine-oxazoline structure provides excellent stereocontrol, making it valuable in the synthesis of enantiomerically pure pharmaceuticals and fine chemicals. Effective in rhodium- and palladium-catalyzed processes where high enantioselectivity is required. Commonly employed in the preparation of chiral intermediates for drugs and biologically active compounds.
