Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling reactions. Its stereochemistry enables high enantioselectivity, making it valuable in the synthesis of chiral pharmaceuticals and fine chemicals. Commonly coordinates with metals like rhodium or ruthenium to form catalytically active complexes. Preferred in reactions where precise stereochemical control is required, such as in the production of single-enantiomer drugs.
