Widely used as a chiral ligand in asymmetric catalysis, this compound plays a key role in enantioselective transformations, particularly in rhodium- and ruthenium-catalyzed asymmetric hydrogenation reactions. It is especially effective in the reduction of prochiral olefins, ketones, and imines, delivering high enantiomeric excess (ee) in the products. Its robust performance in creating stereocenters makes it valuable in the synthesis of pharmaceutical intermediates and fine chemicals where precise chirality is required. The presence of two diphenylphosphino groups and a sulfinamide moiety enhances metal coordination and stereocontrol, contributing to its efficiency and selectivity across a range of catalytic systems.
