Used as a highly efficient chiral catalyst in asymmetric synthesis, particularly in enantioselective C–H functionalization reactions. It enables the selective insertion of carbenoids into C–H bonds with excellent stereocontrol, making it valuable in the synthesis of complex organic molecules, including pharmaceuticals and natural products. Its adamantyl and phthalimido groups enhance steric bulk and electronic properties, contributing to high enantioselectivity and catalyst stability under various reaction conditions.
