Abstract A simple one-pot multicomponent procedure has been developed for the synthesis of pyrrolo[1,2-a]benzimidazole and pyrrolo[1,2-a]quinoxaline derivatives by heating a 1:2:1 molar mixture of a benzimidazole unsubstituted on the imidazole ring, a 2-bromoacetophenone derivative, and a nonsymmetrical activated alkyne in refluxing 2-ethyloxirane. The reaction can be performed under conventional reflux conditions or with microwave irradiation. |
