Used as a highly effective chiral ligand in asymmetric catalysis, particularly in enantioselective transformations such as hydrogenation and cross-coupling reactions. Its rigid, sterically hindered structure enhances stereocontrol, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. The presence of trifluoromethanesulfonamide and bulky tert-butyl groups improves both reactivity and selectivity in transition metal-catalyzed processes. Commonly employed with rhodium, ruthenium, or palladium complexes, it enables high enantiomeric excess in the production of chiral intermediates.
