Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation and cross-coupling. Its rigid, sterically defined structure enables high enantioselectivity in the synthesis of chiral pharmaceuticals and fine chemicals. Commonly employed in the production of optically active intermediates where precise stereochemical control is critical. Effective in palladium- and rhodium-based catalytic systems, enhancing reaction efficiency and product purity.
