Widely used as a chiral ligand in asymmetric catalysis, this compound plays a key role in enantioselective transformations such as hydrogenation and cross-coupling reactions. Its rigid structure and well-defined stereochemistry make it especially effective in inducing high enantioselectivity when paired with transition metals like palladium or rhodium. It is commonly employed in the synthesis of pharmaceutical intermediates and fine chemicals where control over stereochemistry is critical. The sulfinamide group enhances stability and facilitates purification, while the dicyclohexylphosphino moiety contributes to strong metal coordination, improving catalytic efficiency.
