Widely used as a chiral catalyst ligand in asymmetric synthesis, this compound plays a key role in enantioselective transformations, particularly in hydrogenation and C–C bond-forming reactions. Its rigid dinaphthophosphepine backbone and tailored steric environment enable high enantioselectivity when paired with transition metals like rhodium or ruthenium. It is especially effective in the asymmetric hydrogenation of prochiral olefins and ketones, delivering chiral intermediates important in pharmaceutical synthesis. The presence of electron-withdrawing trifluoromethyl groups enhances ligand stability and influences metal coordination, improving catalytic efficiency. Due to its modular chirality from chiral amine and binaphthyl components, it supports precise stereochemical control, making it valuable in the preparation of complex bioactive molecules.
