excellent yields and high regioselectivity. The synthetic application of new protocol was extended to the synthesis of known tricyclic drug doxepin as well as a small library of oxepin based derivatives. For the first time, the obtained dibenzo[b,e]oxepinone derivatives were evaluated for their biological activities on the free-living nematode Caenorhabditis elegans as an effective and cost-efficient model
通过直接的分子内邻位酰化反应,从容易获得的2-(苯氧基甲基)苯甲酸中合成了新颖高效的二苯并[ b,e ] oxepin-11(6H)-酮。该方法利用了由可持续的FeCl 2和Cl 2 CHOCH 3作为关键成分的新开发的协作系统。该方法与多种官能团兼容,具有良好的收率和极高的区域选择性。新方案的合成应用扩展到了已知的三环药物多塞平的合成,以及一个基于奥塞平的衍生物的小型文库。首次获得的二苯并[ b,e对] oxepinone衍生物在自由生活的线虫秀丽隐杆线虫上的生物学活性进行了评估,以此作为驱虫药发现的一种有效且具有成本效益的模型系统。
