chemistry, 1,2-disubstituted benzimidazoles represent a privileged class of nitrogen-based heterocycles but, unlike 2-substitued derivatives, few synthetic methods have been reported. In this context, we developed a rapid, metal-free, and straightforward method to prepare a series of 1,2-disubstituted-1H-benzo[d]imidazoles starting from 1,2-phenylendiamines and various aromatic and aliphatic aldehydes in the
在药物化学领域,1,2-二取代苯并咪唑代表了一类特殊的氮基杂环化合物,但与 2-取代衍生物不同,很少有合成方法的报道。在此背景下,我们开发了一种快速、无金属且直接的方法,以1,2-苯二胺和各种芳香族和脂肪族醛为原料制备一系列 1,2-二取代-1 H-苯并[ d ]咪唑。向山试剂的存在。反应在室温下在几分钟内进行,产物收率良好。
