摘要
将巴比妥酸或硫代巴比妥酸、3 甲酰基色酮在乙酸 -乙酸酐溶液 (含乙酸酐 10 % )中进行缩合反应 ,制备了 5 (色酮基 3 次甲基 ) (硫代 )巴比妥酸 .并经元素分析 ,IR ,1HNMR及13
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.
