| Abstract: | s A series of 2-amimo-3-cyano-4-aryl-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydro-4H-benzopyran were synthesized by the condensation of arylaldehydes with malononitrile and 5,5-dimethyl-1,3-cyclohexanedione under ultrasonic irradiation without catalyst. The structure of the product was determined by IR, 1H NMR spectra, and single crystal X-ray diffraction analysis. |
