Used as a chiral ligand in asymmetric catalysis, particularly in transition-metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling reactions. Its rigid backbone and stereogenic centers enable high enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. The anthracenyl group enhances π-stacking interactions, improving catalyst stability and selectivity. Effective in palladium- and rhodium-based catalytic systems for producing enantiomerically pure compounds.
