Used as a chiral auxiliary or ligand in asymmetric synthesis, enabling the formation of enantiomerically enriched compounds. Its oxazoline core provides a rigid structure that coordinates well with transition metals, making it valuable in catalytic reactions such as enantioselective hydrogenation and C–C bond formation. Commonly employed in pharmaceutical synthesis where stereochemical control is critical. The tert-butyl and pyridine groups enhance steric bulk and metal coordination, improving selectivity and catalyst stability.
