Several novel fused heterocyclic systems which have rings containing N/O or N/S have been synthesized through a facile one-pot method by the treatment of substituted 2-(benzo[d]thiazol-2-yl)phenol and cyanogen bromide in THF and NEt3. This one-pot method contains tough ring-opening of thiazole, special intermolecular rearrangement and ring-closing reactions. The newly synthesized compounds were characterized
通过简便的一锅法,通过在THF中处理取代的2-(苯并[d]
噻唑-2-基)
苯酚和
溴化氰,合成了几种具有含N / O或N / S环的新颖稠合杂环系统和NEt 3。这种一锅法包含
噻唑的强力开环,特殊的分子间重排和闭环反应。通过HR-MS,1 H-NMR,13 C-NMR光谱数据和DFT计算分析对新合成的化合物进行了表征。还通过X射线晶体学分析确定了2a。
