[2,4-Bis(arylamino)thiazol-5-yl]-(1-methyl-1H-benzimidazol-2-yl)methanones, as the analogs of the cytotoxic marine alkaloid dendrodoine, are synthesized and characterized by elemental analysis, IR, NMR, and Mass spectral data. The thiourea derivatives provide four ring atoms for the thiazole ring construction and thus act as [CNCS] synthons. The remaining carbon of the thiazole is sourced from 2-(
合成了[2,4-双(芳基氨基)噻唑-5-基]-(1-甲基-1 H-苯并咪唑-2-基)甲酮,作为细胞毒性海洋生物碱树突藤碱的类似物,并通过元素分析对其进行了表征, IR,NMR和质谱数据。硫脲衍生物为噻唑环的结构提供了四个环原子,因此可作为[C N C S]合成子。噻唑的剩余碳源于2-(2-溴乙酰基)-1-甲基-1 H-苯并咪唑。该[4 + 1]杂环化反应被用于合成新型的1-甲基-1 H-苯并咪唑衍生物。J.杂环化学,(2009)。
