Resumen

We describe the synthesis of pyrrolo-, furo- and thieno[3,2-b]pyridines substituted by alkyl-, arylamino or NH 2 groups from irradiation of 2- pyrrolyl-, 2-furyl-, and 2-thienylalkene imines under mild reaction conditions. We also describe the irradiation of 3-pyrrolyl-, 3-furyl-, and 3- thienylalkene imines, which yields pyrrolo[3,2-c]pyridines in all cases. The mechanism for this procedure is proposed. The compounds obtained can potentially be used in medicinal chemistry.
