Widely used as a chiral ligand precursor in asymmetric catalysis, particularly in transition-metal-catalyzed reactions. It plays a key role in enantioselective transformations such as hydrogenation, carbon-carbon bond formation, and conjugate addition reactions. Due to its rigid backbone and well-defined stereochemistry, it helps achieve high enantiomeric excess in the synthesis of pharmaceutical intermediates and fine chemicals. Commonly employed in rhodium- and ruthenium-catalyzed asymmetric hydrogenations of olefins and ketones, it enables efficient production of single-enantiomer products important in drug development. Its sulfinamide group allows for easy modification and coordination control, making it valuable in designing chiral catalysts for complex organic syntheses.
