A series of novel compounds (8a–21b) were designed and synthesized based on 2-phenyl-1H-benzo[d]imidazole. Compound 18b showed the most potent in vitro growth inhibitory activity and significant tubulin polymerization inhibitory activity.

A new series of 6-substituted 1H-benzimidazole derivatives were synthesized by reacting various substituted aromatic aldehydes with 4-nitro-o-phenylenediamine and 4-chloro-o-phenylenediamine through condensation using sodium metabisulfite as the oxidative reagent. The N-substituted 6-(chloro/nitro)-1H-benzimidazole derivatives were prepared from the 6-substituted 1H-benzimidazole derivatives and substituted
以焦亚硫酸钠为氧化试剂,将各种取代芳香醛与4-硝基邻苯二胺、4-氯邻苯二胺进行缩合反应,合成了一系列新的6-取代1H-苯并咪唑衍生物。 N-取代的6-(氯/硝基)-1H-苯并咪唑衍生物由6-取代的1H-苯并咪唑衍生物和取代的卤化物使用碳酸钾通过常规方法以及通过暴露于微波辐射来制备。采用微波辅助方法合成了 76 种 1 H -苯并咪唑衍生物,产率中等至优异(40% 至 99%)。化合物1d 、 2d 、 3s 、 4b和4k对大肠杆菌、粪链球菌、MSSA(甲氧西林敏感金黄色葡萄球菌菌株)和 MRSA(耐甲氧西林金黄色葡萄球菌菌株)表现出有效的抗菌活性,具有 MIC(最小抑制)与环丙沙星 (MIC = 8–16 μg mL -1 ) 相比,化合物 4k 在 2 至 16 μg mL -1之间,特别是化合物4k对白色念珠菌和黑曲霉表现出有效的真菌活性,MIC 范围在 8 至 16 μg mL -1

geometry of the synthesized complexes 1 and 2 was confirmed by single-crystal X-ray diffraction study. A wide range of benzimidazole derivatives (32 examples) up to 94% isolated yield has been derived via acceptorlessdehydrogenative coupling of primary alcohols with derivatives of o-phenylenediamines. The present protocol operates smoothly with only 1 mol% catalyst loading. Furthermore, the mechanistic
