Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations. Its sterically hindered structure and well-defined chiral environment make it effective in promoting high enantioselectivity in reactions such as asymmetric hydrogenation, C–C bond formation, and transfer hydrogenation of prochiral ketones and imines. Commonly employed with transition metal complexes like ruthenium or rhodium to achieve efficient stereocontrol in the synthesis of pharmaceuticals and fine chemicals.
