Used as a highly effective chiral ligand in asymmetric catalysis, particularly in enantioselective hydrogenation reactions. Its sterically bulky and electron-rich structure enhances selectivity and reactivity with transition metals like rhodium and ruthenium, enabling the synthesis of chiral molecules in pharmaceuticals and fine chemicals. Widely applied in the production of optically active intermediates where high enantiomeric excess is critical. The compound’s rigid framework stabilizes metal-ligand complexes, improving catalyst performance under mild reaction conditions.
