摘要

In the reactions of α-cyanocinamonitrile or β-cyano-β-carbo-thoxy styrene with 5,5-dimethyl-1,3-cyclohexanedione in the presence of ammonium acetate under microwave irradiation without solvent, the 2-amino-5,6,7,8-tetrahydro-5-oxo-4-aryl-7,7-dimethyl-4H-benzo-[b]-pyran derivatives were obtained.However, in the reasons of arylidenecyanoacetamide with 5,5-dimethyl-1,3-cyclohexanedione under the same reaction conditions, the acridine derivatives were obtained. The structures of the products were determined by single crystal X-ray diffraction analysis.
