【Abstract】 α,β-unsaturated acyl-substituted imido derivatives are a kind of important electron-deficient alkenes and widely applied in synthesis.In this paper,a new synthetic method of these alkenes is developed and the catalytic mechanism is discussed.With LiCl as the catalyst,the products are synthesized with succinimides or phthalimide、crotonic anhydride in the present of triethylamine at low temperature.The reactions proceed smoothly in the given condition with good yields.更多还原
