Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective hydrogenation reactions. Its phosphine-oxazoline structure enables high stereocontrol, making it valuable in the synthesis of chiral pharmaceuticals and fine chemicals. Effective in rhodium- and iridium-catalyzed reactions, it helps produce single-enantiomer compounds important in drug development. The rigid piperidine backbone and bulky diphenylphosphino group enhance catalyst stability and selectivity.
