SYNTHESIS OF SULPHANYLAMIDIE DERIVATIVES 1,4-DIHYDRO-4-OXOPYRIMIDINES
The modified method of synthesis of 4-oxopyrimidins, contained sulphanylamidic groups in first (nucleosid's) position is described. The composition and construction of the received salts of 4-oxopyrimidins and 1,4-dihydro-4-oxopyrimidins are confirmed by data of the element (C, H, N, S, Cl) analysis, a nuclear magnetic resonance (NMR 1H) and IR-spectroscopy.
