Abstract In the reactions of α‐cyanocinnamonitrile or β‐cyano‐β‐carbothoxy 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 reactions of arylidenecyanoacetamide with 5,5‐dimethyl‐l,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.
