【Abstract】 Enamines were prepared from acetophenone and several secondary amines and examined in the reaction with methyl phenyldiazoacetate catalyzed by copper salts.None of the expected aminocyclopropane product was found after careful examination of the reaction mixture instead of γ-ketoester.A full investigation of the effects of enamines,catalysts,solvents on the reaction was carried out.更多还原
