Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling reactions. Its sterically bulky structure enhances enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. Commonly employed with rhodium, ruthenium, or palladium complexes to achieve high stereochemical control in the formation of carbon–carbon and carbon–heteroatom bonds.
