Used as a chiral bidentate phosphine ligand in asymmetric catalysis, particularly in transition metal-catalyzed enantioselective reactions. It is highly effective in palladium- and rhodium-catalyzed asymmetric hydrogenation and cross-coupling reactions, where it helps induce high enantioselectivity in the synthesis of chiral molecules. Its sterically demanding and electronically tunable structure makes it suitable for promoting asymmetric transformations in pharmaceutical and fine chemical synthesis. Commonly employed in the production of enantiomerically pure intermediates, especially in the development of active pharmaceutical ingredients (APIs).
