A series of benzimidazole-2-thione derivatives was synthesized using a reaction between the macrocyclic aminal 16H,13H-5:12,7:14-dimethanedibenzo[d,i]-[1,3,6,8] tetraazecine (DMDBTA, 5) and various nucleophiles in the presence of carbon disulfide. A full chemical characterization using IR, 1H-, 13C-NMR and GC-MS analyses of the new compounds is provided. These compounds were separated from the reaction mixture by column chromatography (CC) in highly pure form in 15%–51.4% yield.
一系列苯并咪唑-2-硫酮衍生物通过使用碳二硫化物作为溶剂,宏观环状亚胺16H,13H-5:12,7:14-二甲烷二苯并[d,i]-[1,3,6,8]四氮杂环庚烷(DMDBTA,5)与各种亲核试剂的反应来合成。通过红外光谱、氢核磁共振、碳核磁共振和气相色谱质谱分析对新化合物进行了全面的化学表征。这些化合物以高达15%–51.4%的产率从反应混合物中通过柱色谱法分离出来,并以高度纯净的形式得到。
