Abstract
The 3- R -thieno[3,2- d ]pyrimidine-2,4(1 H ,3 H )-diones ( 5a- с ) and 3- R -2-thioxo-2,3-dihydrothieno[3,2- d ]pyrimidin-4(1 H )-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 ). 2-aminothieno[3,2- d ]pyrimidin-4(3 H )-one ( 14a-c , 16 ) were received as a result the interaction the methyl 3-aminothiophene-2-carboxylate with benzoyl- and pyrimidin-2-yl cyanamides.
