Abstract The synthesis of benzimidazoles has been achieved in a one-pot reaction in excellent yield using a newly developed methodology. 2,5-Disubstituted-3-cyanoacetyl indoles were directly condensed with substituted orthophenylenediamine via microwave irradiation under neat, solid support, and conventional conditions in a short time to afford the corresponding products in good yields.

摘要 使用新开发的方法,苯并咪唑的合成以极好的收率在一锅反应中实现。2,5-二取代-3-氰基乙酰吲哚在纯固体载体和常规条件下通过微波辐射直接与取代的邻苯二胺在短时间内缩合得到相应的产物,收率良好。由此获得的产物的结构通过它们的熔点、红外、 1 H NMR、 13 C NMR和质谱数据确认。
