Used as a 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. Effective in rhodium- and ruthenium-based catalytic systems, it helps achieve high ee (enantiomeric excess) in the production of chiral alcohols and amines. Also employed in academic research for developing new asymmetric transformations.
