目的对吡唑[3,4-b]喹啉类化合物的合成方法进行研究。方法用微波辐射,在无溶剂条件下,以对甲苯磺酸为催化剂,使1,3-二苯基吡唑啉酮、苯甲醛和取代苯胺进行反应,反应时间为8～12 min,合成出了目标产物。结果合成出了一系列吡唑[3,4-b]喹啉类化合物,用元素分析、IR和1HNMR对所合成的化合物进行了表征,产率可达到52%～62%。结论该方法操作简单反应时间短产率较高,对环境友好。 Aim To study the synthesis of pyrazolo [3,4-b] quinoline compounds. Methods Using microwave irradiation, 1,3-diphenylpyrazolone, benzaldehyde and substituted aniline were reacted with p-toluenesulfonic acid under the condition of no solvent and the reaction time was 8-12 min to synthesize The target product. Results A series of pyrazolo [3,4-b] quinolines were synthesized. The compounds were characterized by elemental analysis, IR and 1HNMR. The yield was 52% -62%. Conclusion The method is simple in operation, short in reaction time, high in yield and environmentally friendly.
