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’s steric bulk and electronic properties enhance catalyst stability and selectivity. Commonly employed with rhodium, palladium, or iridium complexes, it enables high enantioselectivity in the production of chiral intermediates.
