The condensation reactions between barbituric acid or thiobarbituric acid and 3-formyl chromones were carried out with heating in acetic/acetic anhydride to give 5-(chromon-3-ylmethylidene)(thio)barbituric acids. The structures of the condensed products were characterized by elemental analysis, IR, 1H NMR and 13C NMR spectroscopies.

Key words: 3-formyl chromone, barbituric acid, 5-(chromon-3-ylmethylidene)(thio)barbituric acid, synthesis
