Used as a chiral ligand or catalyst in asymmetric synthesis, particularly in enantioselective transformations where high stereocontrol is required. Its rigid bis-oxazoline structure enables effective coordination with metal centers such as copper, zinc, or palladium, making it valuable in catalyzing reactions like cyclopropanations, Diels-Alder, and aldol reactions. The stereochemistry (S,R configuration) enhances enantioselectivity, allowing the production of optically active compounds important in pharmaceutical and fine chemical industries. Its bulky tert-butyl groups help shield one face of the substrate, improving selectivity. Commonly employed in research settings for developing chiral molecules with high purity.
