  Interaction of 3-acetoacetyl-2H-chromen-2-one with azanucleophilic reagents

  摘要：

  The reactions of 3-acetoacetylchromen-2-one with mono-and binucleophilic reagents, under the action of microwave irradiation have been studied. It was shown that depending on the nucleophilicity of the reactant new heterocyclic systems were formed involving the oxo group of the substituent in position 3 of the heterofragment, its opening, or recyclization.
