A highly improved one-pot procedure for the synthesis of diazepinones, which incorporate a bioactive quinoline nucleus, under catalyst-, and solvent-free environment has been developed. The method allowed us to achieve the products in high yields without requiring a chromatographic separation. All new quinolyldibenzo[b,e][1,4]diazepinones 6a–h thus obtained were further treated to achieve N10–allylated
在无催化剂和无溶剂的条件下,已经开发出一种高度改进的一锅合成二氮杂pin酮的方法,该方法掺入了具有生物活性的喹啉核。该方法使我们无需色谱分离即可获得高收率的产品。由此获得的所有新的喹啉基二苯并[ b,e ] [1,4]二氮杂庚酮6a - h都经过简单的烯丙基化处理,从而获得了N10-烯丙基化产物7a - h 。根据元素分析,质量,1 H NMR,13建立了所有新合成化合物的结构C NMR,IR光谱数据,2D NMR实验和单晶X射线研究。通过体外抗菌活性研究,发现它们都对革兰氏阳性(肺炎链球菌,破伤风梭菌和枯草芽孢杆菌),革兰氏阴性(鼠伤寒沙门氏菌,弧菌和大肠埃希氏菌),结核分枝杆菌H37RV细菌和白色念珠菌等真菌具有活性。和烟曲霉。还发现所有这些都显示出良好的三价铁还原能力的抗氧化活性。
