Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective transformations such as Michael additions and aldol reactions. Its rigid polycyclic framework and well-defined stereochemistry enable high stereoselectivity when coordinated to metal centers like copper or nickel. Commonly employed in research settings for developing enantiopure pharmaceutical intermediates and fine chemicals. Also explored in supramolecular chemistry for chiral recognition and sensing applications due to its extended aromatic surface and hydrogen-bonding capability.
