Efficient protocols for microwave-assisted catalyzed amination of halogeno-phenothiazines are described. Phenothiazine analogues of Troger's base (PTB) were obtained by condensation of amino-phenothiazines with formaldehyde in HCl/EtOH/H2O and structurally characterized by NMR and XRD analyses. The formation of PTB isomers was predicted by computational analysis based on theoretical methods (DFT and
描述了微波辅助催化胺化卤代吩噻嗪的有效方案。Troger 碱 (PTB) 的吩噻嗪类似物通过氨基吩噻嗪与甲醛在 HCl/EtOH/H2O 中缩合获得,并通过 NMR 和 XRD 分析进行结构表征。PTB 异构体的形成是通过基于理论方法(DFT 和 HF)的计算分析来预测的。基于循环伏安法和紫外/可见吸收/发射光谱数据评估母体氨基吩噻嗪和 PTB 的电子特性。这些化合物在稀溶液和聚集状态下都表现出蓝色荧光发射,其特征是极大的斯托克斯位移 (8900-10300 cm-1)。与不同类型生物分子的相互作用显示出与蛋白质和 DNA 结合的能力,
