Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations such as hydrogenation and transfer hydrogenation reactions. Its rigid, well-defined stereochemistry enhances selectivity when coordinated with transition metals like ruthenium or rhodium, enabling the synthesis of optically active compounds important in pharmaceuticals and fine chemicals. Also employed in the development of chiral catalysts for carbon-carbon bond-forming reactions, contributing to high enantiomeric excess in products.
