Аннотация

Methods for the synthesis of new condensed thieno[3,2-e]pyridines and thieno[3,2-d]pyrimidines have been developed. The reaction of 7,7-dimethyl-2-mercapto-4-(2-furyl)-3-cyano-7,8-dihydro-5H-pyrano[4,3-b]pyridine with chloroacetic acid amides has been established depending on temperature. It has been shown that at high temperatures alkylation and intramolecular cyclization (one pot reaction) occur with the formation of pyrano[4,3-b]thieno[3,2-e]pyridines. New derivatives of condensed tetracyclic thieno[3,2-d]pyrimidines were synthesized by condensation of pyrano[4,3-b]thieno[3,2-e]pyridine carboxamides with orthoformic acid triethyl ester.
