synthesis of 3-(1H-benzo[d]imidazol-1-yl)isoindolin-1-one derivatives by a one-pot, three-component condensation reaction of phthalaldehydicacid, primary amine, and 2-mercaptobenzimidazole or 2-hydroxybenzimidazole is described. By using EtOH–AcOH (v/v, 15:1) as the solvent system, the reaction proceeds smoothly to give corresponding products in good yields.
一种简单高效的方法,可通过邻苯二酸,伯胺和三价胺的一锅三组分缩合反应合成3-(1 H-苯并[ d ]咪唑-1-基)异吲哚啉-1-酮衍生物描述了2-巯基苯并咪唑或2-羟基苯并咪唑。通过使用EtOH-AcOH(v / v,15:1)作为溶剂体系,反应可以顺利进行,从而以高收率得到相应的产物。
