AbstractIn this study, a synthetic method to access benzo[4,5]imidazo[2,1‐a]isoquinolines is developed by the reaction of 2‐(2‐bromoaryl)benzimidazoles with 1,3‐diketones under basic conditions. A reaction pathway involving the initial formation of a C−C coupled intermediate by nucleophilic aromatic substitution and subsequent deacylative cyclocondensation is proposed for this process.
摘要 在本研究中,通过 2-(2-溴芳基)苯并咪唑与 1,3-二酮在碱性条件下的反应,开发了一种获得苯并[4,5]咪唑并[2,1-a]异喹啉的合成方法。提出了这一过程的反应途径,包括通过亲核芳香取代最初形成 C-C 偶联中间体,以及随后的脱酰基环缩合反应。
