A series of 2-cyano-3-aryl-3-(3,4-dihydro-1(2H)-naphthalene-one-2-yl) propionitrile derivatives and 2-aminopyran derivatives were synthesized by the KF-Al2O3-catalyzed reaction of malononitrile with 2-arylmethylidene-3,4-dihydro-1(2H)-naphthalenone, 2,6-biarylmethylidene cyclohexanone, or 2,5-biarylmethylidene cyclopenanone in DMF at room temperature. The structure of the later was confirmed by x-ray analysis.
