Used as a chiral ligand in asymmetric catalysis, particularly in transition-metal-catalyzed reactions such as palladium-catalyzed cross-couplings and rhodium-catalyzed hydrogenations. Its rigid backbone and stereogenic centers enable high enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. Commonly employed in the production of chiral intermediates where precise stereochemical control is required.
