scheme for the synthesis of 3-substituted functionalized flavones was developed. The reaction of flavanone and glyoxylic acid in ethanol in the presence of the catalytic amount of sulphuric acid at reflux temperature for 2–3 h yielded good to excellent functionalized flavones. As per present scenario for the synthesis of different substituted flavones, this method represents mild reaction conditions, low-cost
开发了一种温和而有效的合成3-取代的功能性黄酮的方案。黄烷酮和乙醛酸在乙醇中的反应,在催化量的硫酸存在下,在回流温度下反应2–3 h,可以得到很好的官能化黄酮。按照目前用于合成不同取代的黄酮的方案,该方法代表了温和的反应条件,低成本的催化剂,广泛的底物范围以及高收率,这使其成为更加可靠和便捷的合成策略。
