Analogs of 4-(2',4'-difluorobiphenyl-4-yl)-2-methyl-4-oxobutanoic acid (I, flobufen), containing a double bond (II, IV, V, VII, VIII) or a methyl group in position 3 (VI) were prepared.Their antiinflammatory activity was evaluated and compared with that of flobufen.None of the mentioned analogs reached the activity of the standard.Isomerization of the unsaturated derivatives is connected with a shift of the double bond, Z-E transformation or lactonization.Reaction conditions and spectra of the compounds prepared are described.
