This compound is widely used as a chiral ligand precursor in asymmetric catalysis, particularly in transition-metal-catalyzed reactions. It plays a key role in the synthesis of enantiomerically enriched compounds, making it valuable in pharmaceutical and fine chemical industries. Due to its well-defined stereochemistry and bulky dicyclohexylphosphanyl group, it forms highly selective catalysts for asymmetric transformations such as hydrogenation, C–C bond formation, and allylic alkylation. Its sulfinamide moiety allows for easy handling and purification, while the chiral centers ensure high stereocontrol when coordinated to metals like palladium, rhodium, or ruthenium. It is especially effective in reactions requiring high enantioselectivity and catalyst turnover.
