Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations. Its rigid oxazoline framework enables high stereocontrol in reactions such as cyclopropanations, Diels-Alder, and aldol reactions. Commonly coordinates with metals like copper or palladium to form catalysts that deliver high enantiomeric excess. Valued in pharmaceutical synthesis for constructing chiral centers with precision.
