A new one‐pot palladium‐catalyzed process between N‐tosylhydrazones, N‐(dihalophenyl)‐imidates, and amines was designed. This reaction involves Barluenga cross‐coupling and N‐arylation followed by cyclization to produce functionalized benzimidazoles. During this transformation, one CC bond and two CN bonds were created by a single palladium‐catalyzed reaction. Depending on the starting materials
设计了一种新的单锅钯催化方法,该方法在N-甲苯磺酰hydr,N-(二卤代苯基)-亚氨酸酯和胺之间进行。该反应涉及Barluenga交叉偶联和N芳基化,然后环化生成功能化的苯并咪唑。在这一转变过程中,通过一个钯催化的反应就产生了一个CC键和两个CN键。取决于起始材料,一个5-(1-芳基乙烯基)-1 H的库合成了苯并咪唑。在评估的几种芳基乙烯基苯并咪唑衍生物中,一种化合物在纳摩尔浓度范围内对人结肠癌细胞系(HCT-116)和人肺腺癌上皮细胞系(A549)表现出优异的抗增殖活性。
