Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective transformations such as hydrogenation, allylic alkylation, and Diels-Alder reactions. Its rigid binaphthyl backbone and oxazoline rings provide a well-defined chiral environment, enabling high enantioselectivity when coordinated to transition metals like rhodium, ruthenium, or palladium. Commonly employed in the synthesis of pharmaceuticals and fine chemicals where control of stereochemistry is critical. The ligand’s steric bulk from the tert-butyl groups enhances selectivity by restricting approach of substrates to the metal center in a specific orientation.
