| Description |
6-Amino-5-formyluracils 1 and 5-formyl-6-hydroxyuracils 4 react with
Meldrum 19sacid2inthepresenceofpiperidineascatalystunderthermolyticconditions
to afford 6-carboxy-2,4,7-trioxopyrido[2,3-d]pyrimidines 3 and 6-carboxy-2,4,7trioxopyrano[2,3-d]pyrimidines
5 in good yield. Under identical conditions, 6-amino5-nitrosouracils
6 react with 2 to afford pteridine-6-carboxylic acids 7 in good yields.
