Used as a highly efficient chiral catalyst in asymmetric hydrogenation reactions, enabling the production of enantiomerically pure compounds in pharmaceutical synthesis. Its unique phosphinite-oxazoline ligand structure provides excellent stereocontrol, particularly in the reduction of prochiral olefins and imines. The presence of the iridium(I) center and non-coordinating borate anion enhances catalytic activity and stability under mild reaction conditions. Widely applied in the preparation of chiral intermediates for drugs and fine chemicals where high enantioselectivity is critical.
