摘要：

The alkaline treatment and dehydrogenation of pyridinium salts, obtainable from the S-alkylation of 3,5-dimethylpyridinium 2-alkylthio-1-cyano2-thioxoethylides with some phenacyl bromides, afforded unexpected heterocycles, 3-alkylthio-1-arylcarbonyl-6,8-dimethylthieno[3',4':4,5]imidazo-[1,2-a]pyridines, together with the corresponding 2-alkylthio-1-arylcarbonylthio-6,8-dimethylindolizine-3-carbonitriles.
