chalcones and the ether group in alkenes with the copper in the catalyst is essential for high enantioselectivity, while the π–π stacking interaction between two reactants plays an importantly additional role for high enantioselectivity in asymmetricaziridination. An excellent backbone-controlled stereoselectivity was observed for the AnBOX ligands in asymmetricaziridination, as this will provide very
