Abstract: 本发明公开了一种利用合成樟脑的副产物双戊烯合成香芹酮的工艺,其对双戊烯亚硝基氯化物的合成步骤加以改进,先于反应釜中依次加入异丙醇和浓盐酸形成盐酸异丙醇溶液,并保持反应釜温度为0~1℃;而后向盐酸异丙醇溶液中滴加浓盐酸、双戊烯以及亚硝酸异丙酯,恒温反应0.5~2h,抽滤、洗涤得到双戊烯亚硝基氯。由于异丙醇、盐酸、双戊烯和亚硝酸异丙酯可以混合均匀而不存在分层,其为均相反应,其反应速度比现有技术中的两相反应快,节省反应时间,提高了生产效率,整个过程操作简便,易于工业化生产。

Abstract: The current invention offers a one-pot, two-component green synthetic protocol as potent antioxidant drug candidates of novel synthesized urea analogues. All the compounds were evaluated for in vitro antioxidant studies by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydrogen peroxide (H2O2) methods. In both DPPH and in H2O2 methods, compounds 3a, and 3c exhibited noteworthy antioxidant activity compared with the standard drug ascorbic acid at various concentrations of 25, 50, 75, and 100 µg/mL. The protocol has various advantages such as green synthetic route, short reaction times, excellent yields, simple work-up procedure, no column chromatography, and potential antioxidant agents.
