Used as a chiral catalyst ligand in asymmetric synthesis, particularly in enantioselective transition metal-catalyzed reactions. Its rigid, sterically hindered structure enables high enantioselectivity in transformations such as hydrogenations, C–C bond formations, and cross-coupling reactions. Commonly employed in pharmaceutical synthesis where precise stereochemical control is critical. The trifluoromethanesulfonamide group enhances stability and coordination ability with metals like palladium, rhodium, or iridium, making it suitable for demanding catalytic conditions. Also utilized in the development of novel catalytic systems for fine chemical production.
