A convenient synthetic route to novel 7-substituted benzo[f]thieno[3,2-h]quinazoline and 8-substituted benzo[g,h]dithieno[2,3-e:3′,2′-j]perimidine systems, bearing the fused pyrimidine ring, has been advanced. A commercially available 5-bromopyrimidine was used as the starting material to obtain various polycyclic systems through the sequence of nucleophilic aromatic substitution of hydrogen (the SNH
新型7-取代苯并[f]噻吩并[3,2-h]喹唑啉和8-取代苯并[g,h]二噻吩并[2,3-e:3',2'-j]哌啶系统的便捷合成路线,带有稠合嘧啶环,已经进步。以市售的5-溴嘧啶为原料,通过氢的亲核芳香取代(SNH反应)、Suzuki交叉偶联和氧化光环化的顺序获得各种多环体系。苯并[g,h] 二噻吩并[2,3-e:3',2'-j] 嘧啶的结构证据已通过 X 射线晶体学分析获得。已经对所有新化合物进行了分子轨道计算 (DFT) 以及氧化还原和光学测量。数据表明,报道的多环系统具有用于有机电子应用的潜力。
