The three-component reactions of in-situ-formed N-benzylbenzimidazolium salts, aromatic aldehydes, and active methylene compounds in the presence of triethylamine showed very interesting molecular diversity. The reactions with Meldrum's acid or barbiturate in acetonitrile gave a series of the novel zwitterionic salts in high yields. Under similar reaction conditions, the reactions with malononitrile or ethyl cyanoacetate produced functionalized pyrrolo[1,2-a]benzimidazoles in good yields with an unprecedented regioselectivity.
