Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation and cross-coupling. Its rigid structure and stereogenic centers enable high enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. The anthracene moiety enhances π-stacking interactions, improving catalyst stability and selectivity. Commonly employed in palladium and rhodium complexes for asymmetric transformations.
