Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective synthesis of pharmaceutical intermediates. It forms complexes with transition metals like palladium and copper, enhancing stereochemical control in coupling reactions and cycloadditions. Its rigid oxazoline-quinoline framework provides high enantioselectivity in carbon-carbon and carbon-heteroatom bond-forming reactions. Commonly applied in the preparation of bioactive molecules where precise stereochemistry is critical.
