摘要

Ethyl azidoacetate was reacted with thiophene-2, 3-dialdehyde, in which the two formyl groups are free or in which one of them is blocked as the diethyl acetal, to yield, after cyclization, thieno [2, 3-c] and-[3, 2-c] pyridines and pyridones, respectively. The structures of the intermediate products were established by nmr; a reaction scheme is proposed.[Journal translation]
