The transformations of tetrahydrothieno[3,2-c]-and tetrahydrobenzothieno[2,3-c]pyridines in the reactions with acetylenedicarboxylic ester, alkylpropiolates, and acetylacetylene in alcohols were studied. Tetrahydrobenzothieno[3,2-d]azocines and 2-methoxyethyl-3-vinyl-aminoethylbenzothiophenes were synthesized.
