| Abstract: | The transformations of tetrahydrothieno[3,2-c]-and tetrahydrobenzothieno[2,3-c]pyridines in the reactions with acetylenedicarboxylic ester, alkyl propiolates, and acetylacetylene in alcohols were studied. Tetrahydrobenzothieno[3,2-d]azocines and 2-methoxyethyl-3-vinyl-aminoethylbenzothiophenes were synthesized. Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 5, pp. 1003–1009, May, 2007. |
