The addition of β-ketoacids to 4-(trifluoromethyl)pyrimidin- 2(1 Н )-ones with decarboxylation: an effective method for the synthesis of 4-(2-oxoalkyl)-6-(trifluoromethyl)-3,4-dihydropyrimidin-2-ones

β-Ketoacids reacted with 4-(trifluoromethyl)pyrimidin-2(1Н)-ones according to the mechanism of Michael addition–decarboxylation, forming 4-(2-oxoalkyl)-6-(trifluoromethyl)-3,4-dihydropyrimidin-2-ones.
