The 3-R-thieno[3,2-d]pyrimidine-2,4(1H,3H)-diones (5a-с) and 3-R-2-thioxo-2,3-dihydrothieno[3,2-d]pyrimidine-4(1H)-ones (5d-g) were synthesized using methyl 3-aminothiophene-2-carboxylate and alkyl-, arylisocyanates and isothiocyanates respectively, which in turn converted into its N- и S- alkyl derivates (8a-e, 9a-g).
