Used as a chiral catalyst ligand in asymmetric synthesis, particularly in enantioselective oxidation and cyclization reactions. Its rigid phenanthroline backbone and oxazoline ring enhance stereocontrol, making it valuable in pharmaceutical and fine chemical manufacturing where high enantiomeric purity is required. Effective in copper-catalyzed reactions, it helps form carbon–oxygen and carbon–nitrogen bonds with high selectivity. Also applied in the development of new catalytic systems for sustainable chemistry due to its stability and reusability under various reaction conditions.
