Pyrrolopyrimidines. 2.* Synthesis and oxidative conversions of 5-amino-1,3-Dimethylpyrrolo[3, 2-d]pyrimidine-2, 4-diones

By the action of hydroxylamine-O-sulfonic acid in an alkaline medium on 1,3-dimethyl- and 1,3-dimethyl-7-bromopyrrolo3,2-d]pyrimidine-2,4-diones, their 5-amino derivatives have been obtained. It has been shown that the oxidation of these derivatives leads to the formation of the corresponding tetrazenes and products of deamination, the ratio of which is determined by the type of oxidizing agent and by the reaction conditions. I-Aminoindole behaves analogously.Rostov State University, Rostov-on-Don 344104. Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1131–1137, August, 1995.
