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 pharmaceutical intermediates and fine chemicals. Commonly applied in the production of optically active compounds where stereochemistry is critical, including active pharmaceutical ingredients (APIs). The rigid structure and defined chirality enhance reaction selectivity and yield under mild conditions.
