Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations such as alkylations, aldol reactions, and cycloadditions. Its rigid cycloheptane backbone and oxazoline rings provide a well-defined chiral environment, enhancing stereocontrol in metal-catalyzed reactions. Commonly employed with metals like copper, nickel, or palladium to achieve high enantioselectivity in the synthesis of pharmaceuticals and fine chemicals.
