Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations. Its oxazoline rings coordinate with metal centers like copper or palladium, forming complexes that promote high stereoselectivity in reactions such as cyclopropanations, aldol additions, and conjugate additions. The tert-butyl groups enhance steric bulk, improving enantiocontrol. Commonly applied in pharmaceutical synthesis where precise chirality is critical. Also employed in the development of custom catalysts for fine chemical manufacturing.
