| Abstract: | A Novel condansation of aromatic aldehyde with 2-pyrodone: 4-hydroxy-6-methyl-2-pyridone-1-acetate 1 and its 2 and 3 has been explored. It leads to the formation of arylmethenes 7 or 8 obtained by the reaction of one molecule of aldehyde with two molecules of 2-pyridone-2. The structure of all compounds was determined by pmr, cmr, mass spectra and ir. A reaction mechanism is proposed. |
