以苯丙炔酸与氮甲基苯胺合成的N-甲基-N-苯基-3-丙炔酸胺为原料,通过铁催化氧化、重氮化水解合成了一系列1-甲基-4-苯基-2(1H)喹啉酮衍生物。并对喹啉酮衍生物产物进行质谱、核磁共振氢谱和碳谱的定性及结构表征。此方法路线简单,反应条件温和,合成的各种目标产物产率和纯度较高,实验结果令人满意。 N-methyl-N-phenyl-3-propynyl amine synthesized from phenylpropynic acid and N-methylaniline was used as the starting material to synthesize a series of 1-methyl-4 -phenyl-2 (1H) quinolinone derivatives. The qualitative and structural characterization of the quinolinone derivatives were also studied by MS, 1H NMR and GC. The method has the advantages of simple route, mild reaction conditions, high yield and purity of the synthesized target products and satisfactory experimental results.
