Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective hydrogenation and transfer hydrogenation reactions. Its rigid backbone and well-defined stereochemistry make it effective in inducing high enantioselectivity when coordinated to transition metals such as ruthenium, rhodium, or iridium. Commonly employed in the synthesis of chiral amines, alcohols, and pharmaceutical intermediates where stereochemical purity is critical. Also utilized in organocatalysis and as a building block for more complex chiral catalysts.
