Used as a chiral ligand in asymmetric catalysis, enabling the synthesis of enantiomerically enriched compounds in pharmaceuticals and fine chemicals. Its rigid, bidentate structure enhances stereocontrol in transition-metal-catalyzed reactions such as aldol, Mannich, and Michael additions. Also employed in organocatalysis for promoting carbon–carbon bond-forming reactions with high enantioselectivity. Soluble in common organic solvents, it facilitates homogeneous reaction conditions and is often paired with copper or nickel complexes for improved catalytic efficiency.
