摘　　要：In the reactions of α-cyanocinnamonitrile or β-cyano-β-carbo-thoxy styrenewith 5,5-dimethyl-1,3-cyclohexanedione in the presence of ammonium acetate under microwaveirradiation without solvent, the2-amino-5,6,7,8-tetrahydro-5-oxo-4-aryl-7,7-dimethyl-4H-benzo-[b]-pyran derivatives were obtained.However, in the reactions of arylidenecyanoacetamide with 5,5-dimethyl-1,3-cyclohexanedione underthe same reaction conditions, the acridine derivatives were obtained. The structures of the productswere determined by single crystal X-ray diffraction analysis.In the reactions of α-cyanocinnamonitrile or β-cyano-β-carbo-thoxy styrenewith 5,5-dimethyl-1,3-cyclohexanedione in the presence of ammonium acetate under microwaveirradiation without solvent, the2-amino-5,6,7,8-tetrahydro-5-oxo-4-aryl-7,7-dimethyl-4H-benzo-[b]-pyran derivatives were obtained.However, in the reactions of arylidenecyanoacetamide with 5,5-dimethyl-1,3-cyclohexanedione underthe same reaction conditions, the acridine derivatives were obtained.
