On heating at pH 6.86, 4-(N,N-dialkylthiocarbamoylthio)-5-nitropyrimidines are transformed into dithiolopyrimidines, which are either oxidized to bis(4-dialkylthiocarbamoylpyrimidin-5-yl) disulfides or converted into 4,6-diamino-5-nitropyrimidine derivatives with carbon disulfide elimination. The direction of the reaction is determined by the nature of a substituent in position 2 of pyrimidine and the bulk of the thiocarbamate substituent. Mechanistic schemes for these processes were proposed.

ines has been accomplished by the cyclization of the corresponding intermediate 5-amino-4-chloro-6-(alkylamino)pyrimidines promoted by alkoxides and various N,N-dimethyl amides, where the latter act as solvent–reagents. By this three-component condensation reaction we are able to introduce an alkyl group in the 8 position of the purine ring with the concomitant nucleophilic replacement of the 6-chloro

Treatment of 6-chloro-4-dialkylamino-5-nitropyrimidines (Ia–d) under acidic conditions resulted in ringcleavage and formation of 3-amino-3-dialkylamino-2-nitroacrylonitriles (IIIa–d). Similar treatment of 4-amino- or 4-alkylamino-6-chloro-5-nitropyrimidines also gave acrylonitriles (IIIe–i) but 4-amino- or 4-alkylamino-5-nitropyrimidin-6(1H)-ones (IIe–i) were formed at the same time.
