benzophenanthrothiophenes 14–17 through Elbs cyclodehydration of ortho-methylated aroylbenzo[b]thiophenes is described. The occurrence of a rearrangement of the thiophene ring in the course of the cyclization is discussed as well as the influence of the temperature on a concurrent cyclodehydration process. Several of these poly-condensed thiophenes were found carcinogenic in mice.
描述了通过邻甲基化的芳酰基苯并[ b ]噻吩的Elbs环脱水反应合成苯并萘噻吩9和10以及苯并噻吩噻吩14-17。讨论了环化过程中噻吩环重排的发生以及温度对同时进行的环脱水过程的影响。发现这些缩聚噻吩中的几种在小鼠中具有致癌性。
