摘要：

A synthesis for two new polycyclic heterocyclic ring systems is reported. Cyclization of pyrrolidinocarboxamide derivatives of ethyl 3-(pyrrol-1-yl)thieno[2,3-b]pyridine-2-carboxylate (4) and ethyl 3,5-di(pyrrol-1-yl)dithieno[3',2'-e:2,3-b]pyridine-2,6-dicarboxylate (11) afford iminium salts that were transformed into the new heteropolycyclic compounds (6) and (13), respectively.
