Used as a chiral ligand in asymmetric catalysis, particularly in transition-metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling reactions. Its rigid dinaphthyl backbone and stereogenic centers enable high enantioselectivity in the synthesis of chiral molecules. Commonly employed in pharmaceutical and fine chemical industries for the production of enantiomerically pure compounds. Effective in palladium- and rhodium-based catalytic systems where precise stereocontrol is required. Also utilized in research settings for developing new asymmetric transformations due to its strong coordination ability and configurational stability.
