Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations. It forms complexes with transition metals like copper or nickel, enabling highly stereoselective carbon-carbon bond-forming reactions. Commonly applied in catalytic asymmetric alkylation and cyclopropanation reactions, where it helps achieve high enantiomeric excess. Its rigid, bidentate structure enhances stereocontrol, making it valuable in the synthesis of chiral intermediates for pharmaceuticals and fine chemicals.
