Readily available 2-acylamino-3,3-dichloroacrylonitriles are sequentially treated with methyl mercaptoacetate in the presence of sodium methylate and with sulfuric acid to furnish the methyl ester of 7-amino-2-oxo-3H-thieno[2,3-b][1, 4]thiazine-6-carboxyl

Enamidonitriles of the general formula Cl(X)C=C(CN)NHCOR readily react with methyl sulfanylacetate to give tri-or tetra-substituted thiophenes, which can be converted into new functional derivatives of thieno[3,2-d]pyrimidine and thieno[3,4-d]imidazole.
