提出了一种4-(1H)-喹诺酮衍生物合成方法. 以3,3-二乙氧基丙酸乙酯和苯胺为原料, 生成中间体3-(苯基亚氨基)丙酸乙酯, 再经热环化或微波促进环化两步反应制备4-(1H)-喹诺酮, 并以此方法合成了7个溴代或甲氧基取代的4-(1H)-喹诺酮衍生物.

A simple and new synthetic approach to 4-(1H)-quinolones was described. This method was started from ethyl 3,3-diethoxypropanoate and aniline via a synthetic sequence of preparation of key intermediate 3-(phenylimino)propionate and cyclization reaction. The brominated or methoxy substituted derivatives were synthesized by this new method as well.
