Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations such as alkylations, aldol reactions, and cycloadditions. Its rigid, C2-symmetric structure enhances stereocontrol, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. Commonly coordinates with metals like zinc, copper, or nickel to form active catalytic complexes. Preferred in reactions where high enantioselectivity and yield are critical.
