Abstract

The effect of some active methylene containing heterocyclic compounds, namely barbituric acid, thiobarbituric acid and 3-methyl-1-phenylpyrazol-5-one on a-cyano-3,4,5-trimethoxycinnamonitrile and ethyl a-cyano-3,4,5-trimethoxycinnamate (1a,b) was investigated. The structure of the new products was substantiated by their IR,1H-NMR and mass spectra.
Keywords: Barbituric and thiobarbituric acids; pyrazolone; and activated nitriles Barbituric and thiobarbituric acids; pyrazolone; and activated nitriles
