Used as a chiral auxiliary or ligand in asymmetric synthesis, particularly in enantioselective catalysis. Its rigid oxazoline framework enables high stereocontrol in reactions such as aldol condensations, alkylations, and cycloadditions. Commonly employed in the synthesis of pharmaceuticals and fine chemicals where precise stereochemistry is critical. The tert-butyl groups enhance steric bulk and stability, improving enantioselectivity in metal-catalyzed transformations. Also applied in the development of novel catalysts for industrial and academic research settings.
