Used as a chiral ligand in asymmetric catalysis, particularly in transition-metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling reactions. Its sterically hindered structure and well-defined stereochemistry enable high enantioselectivity in the synthesis of complex organic molecules, including pharmaceutical intermediates and natural products. Commonly employed in palladium- and rhodium-catalyzed transformations where precise control of stereochemistry is critical. The sulfinamide group acts as a directing and activating moiety, enhancing reactivity and selectivity. Widely applied in research and industrial settings for the development of enantiopure compounds.
