| Abstract: | The alkylation of acetonyl, anionic sigma-complexes of the 5-nitropyrimidine series with geminal substitution in the 2 or 6 position is studied. Depending on the position of the geminal substitution, the C(5) or the N(1) atom is alkylated to form 2,5- or 1,6-dihydropyrimidine, respectively.See 1] for Communication 8.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1238–1243, September, 1990. |
