Резюме:An effective method for the synthesis of previously undescribed 1,3,4,5,6a,7,8,9-octahydropyrimido[4,5-e]indolizine- and 1,3,4,5,7,8,9,10-octahydro-2H-pyrimido[5,4-c]quinolizine-6-carboxylic acids by hydrolysis and decarboxylation of new spiro-substituted derivatives was proposed. The corresponding spirocyclic derivatives were obtained by boiling of 6-dialkylamino-1,3-dimethyl-5-formyluracils with Meldrum's acid in acetonitrile. The reaction proceeds according to the tert-amino effect mechanism without the release of Knoevenagel condensation products.
