Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective oxidation and C–C bond-forming reactions. Its rigid V-shaped structure enhances stereocontrol, making it effective in catalyzing reactions such as enantioselective epoxidation of allylic alcohols and hetero-Diels–Alder processes. Commonly employed with metals like vanadium or copper to form highly selective catalysts in pharmaceutical and fine chemical synthesis.
