Used as a chiral catalyst ligand in asymmetric synthesis, enabling high enantioselectivity in catalytic reactions such as hydrogenation and cross-coupling. Its bulky, well-defined chiral structure makes it effective in promoting stereocontrolled transformations, particularly in pharmaceutical and fine chemical manufacturing. Commonly employed with transition metals like rhodium or ruthenium to form active catalytic complexes. Also applied in the development of enantiopure compounds where precise stereochemistry is critical.
