Synthesis of 7-aminopyrido[2,3-d]pyrimidine-2,4,5-triones [Elektronische Daten] [N. Smirnova, N. Cherdantseva, O. Burova, V. Nesterov, T. Safonova] 6-Aminouracils and N-substituted derivatives are cyanoacetylated to give 5-cyanoacetyl-6-aminouracils. In the presence of bases these are converted to pyrido[2,3-d]pyrimidine-2,4,5-triones in high yields. Plenum Publishing Corporation, 1991 Smirnova N.
