| | 3-CYANO-4-METHYLCOUMARIN Usage And Synthesis |
| Uses | 4-Methyl-2-oxo-2H-chromene-3-carbonitrile is a useful reactant for various organic reaction and synthesis of organic compounds. | | Synthesis Reference(s) | Journal of the American Chemical Society, 75, p. 1886, 1953 DOI: 10.1021/ja01104a032 | | General Description | 3-Cyano-4-methylcoumarin is a 3-substituted 4-methylcoumarin derivative. Its structural properties, vibrational frequencies and electronic spectra has been studied by density functional theory (DFT). It has been reported to be formed during the Knoevenagel condensation of o-hydroxyacetophenone with ethyl cyanoacetate catalyzed by calcined Mg-Al hydrotalcite. Synthesis of 3-cyano-4-methylcoumarin, via condensation of o-hydroxyacetophenone with ethyl cyanoacetate in the presence of sodium ethylate, has been reported. |
