For the first time 6,7,8-trifluoro- and 5,6,7,8-tetrafluorinated 3-benzoylflavones have been obtained. Their reactions with aminoacids and biogenic amines were studied in comparison with polyfluorinated 3-acetyl-2-methylchromones. For chromones, reactions at the C-2 are preferred, which lead to the pyrone ring opening to form N-substituted aminoenketones. Whereas in the case of flavones the main route

Routes of modification of 5,6,7,8-tetrafluoro-3-methoxycarbonyl-2-(4-methoxyphenyl)-4H-chromen-4-one and its decarboxylated analogs in the reactions with aliphatic amines were studied and the biological activity of both the starting compounds and the products was tested. It was found that 5,6,7,8-tetrafluoro-3-methoxycarbonyl-2-(4-methoxyphenyl)-4H-chromen-4-one under the action of primary amines underwent
