描述了苯并[ b ]菲[2,3- d ]噻吩和苯并[ b ]菲[3,2- d ]噻吩的K-氧化物和K-亚胺的合成。母体碳氢化合物1和2用四氧化和偏高碘酸钠氧化,如此形成的二醛12和18环化为相应的环氧化物1a,12b-二氢苯并[ b ]氧杂壬酸[9,10]菲咯啉[2,3- d ] ]噻吩(7)和1a,12b-二氢苯并[ b ]氧杂诺[9,10]菲[3,2- d ]噻吩(13)。与叠氮化钠的环氧乙烷的反应得到叠氮基醇的混合物,反过来,转化到thiaarene亚胺1A,12B二氢ħ -苯并[ b ] azirino- [9,10]菲并[2,3- d ]噻吩(8)和1a,12B二氢ħ -苯并[ b ]氮丙啶并[9,10]菲并[3,2- d ]噻吩(14),分别与三的辅助ñ丁基膦。
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。
