Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation and cross-coupling. Its steric bulk and electron-donating properties enhance enantioselectivity and reaction efficiency. Commonly employed in the synthesis of pharmaceutical intermediates and fine chemicals where high optical purity is required. Shows good performance with rhodium and palladium complexes, enabling the production of enantiomerically enriched compounds under mild conditions.
