Used as a highly effective chiral ligand in asymmetric catalysis, particularly in transition-metal-catalyzed reactions such as asymmetric hydrogenation and C–C bond formation. Its rigid, sterically hindered structure enhances enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. Commonly employed with rhodium or ruthenium complexes, it enables high yield and excellent enantiomeric excess in the production of chiral alcohols and amines.
