Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective transition metal-catalyzed reactions. It plays a key role in promoting high stereoselectivity in carbon-carbon bond-forming reactions such as hydrogenation, allylic alkylation, and cross-coupling processes. Its rigid, bidentate structure enhances metal-ligand coordination, improving catalytic efficiency and enantiomeric excess in the synthesis of pharmaceuticals and fine chemicals. Commonly employed with palladium, rhodium, or ruthenium complexes, it enables the production of single-enantiomer compounds important in drug development and agrochemicals.
