An efficient method for the synthesis of the thieno[2,3-c:4,5-c']dipyrrole ring system is described. Reaction of 13 with sodium azide followed by the treatment with triphenylphosphine and water gave parent compound 4. Reaction of 13 with benzylamine or aniline afforded N,N'-disubstituted derivatives 15 and 16 respectively. Diels-Alder reaction of 15 with DMAD gave cycloadducts 17 and 18. Oxidative
描述了一种合成噻吩并[2,3- c:4,5- c ']双吡咯环系统的有效方法。13与叠氮化钠反应,然后用三苯膦和水处理,得到母体化合物4。13与苄胺或苯胺的反应分别得到N,N′-二取代的衍生物15和16。15与DMAD的Diels-Alder反应产生环加合物17和18。从17和18氧化去除亚胺桥得到二苯并噻吩19。
