Abstract

The reaction of ethyl azidoacetate with the monoaldehydes of furan, thiophene and seleno- phene yields furo-, thieno-, and selenolo [2, 3-b]-and [3, 2-b] pyrroles. Only pyrrolo [2, 3-b] pyrrole could be prepared by this route using ethyl 4-formylpyrrole-2-carboxylate as the substrate. The thieno-and selenolo [3, 2-b] pyrroles also could be obtained by the action of ethyl bromoacetate on 3-acetamidothiophene-2-aldehyde, or the corresponding selenolo ...
