5-dimethoxytetrahydrofuran with 3-aminothieno[2,3-b]pyridines afford a number of substituted 3-(1H-pyrrol-1-yl)thieno[2,3-b]pyridines. The possibility of the reaction and the yield of the product are determined by the character of a substituent in position 2 of thieno[2,3-b]pyridine. The Curtius rearrangement of 2-acylazido-3(1H-pyrrol-1-yl)thieno[2,3-b]pyridines yields 4,5-dihydropyrido[3",2":4,5]thieno[2
2,5-二甲氧基四氢呋喃与 3-氨基噻吩并 [2,3-b] 吡啶的反应提供了许多取代的 3-(1H-吡咯-1-基) 噻吩并 [2,3-b] 吡啶。反应的可能性和产物的产率由噻吩并[2,3-b]吡啶2位取代基的特征决定。2-acylazido-3(1H-pyrrol-1-yl)thieno[2,3-b]pyridines 的 Curtius 重排产生 4,5-dihydropyrido[3",2":4,5]thieno[2,3- e]吡咯并[1,2-a]吡嗪-4-酮。4-甲氧基甲基-6-甲基-3-(1H-吡咯-1-基)噻吩并[2,3-b]吡啶-2-羧酸乙酯的分子和晶体结构由X射线衍射分析确定。
