New substituted 2-[2-(4-nitrobenzoyl)hydrazinylidene]-4-oxobut-2-enoic acids have been synthesized by condensation of 4-nitrobenzohydrazide with 4-aryl-2,4-dioxobutanoic acids, and their intramolecular cyclization in the presence of propionic anhydride afforded the corresponding substituted 3-[2-(4-nitrobenzoyl)hydrazinylidene]furan-2(3H)-ones. The synthesized compounds were evaluated for their antinociceptive

Abstract The substrate scope of the procedure for the synthesis of 2-[2-(4-R-benzoyl)hydrazinylidene]-4-oxobutanoic acids was expanded, and their intramolecularcyclization in the presence of propionic anhydride was studied. The synthesized compounds were evaluated for their anti-inflammatory activity and acute toxicity. Some compounds showed a significant anti-inflammatory activity at a level comparable

proposed for the synthesis of substituted 2-[2-(furan-2-carbonyl)hydrazinylidene]-4-oxobutanoic acids by the reaction of 4-aryl-2,4-dioxobut-2-enoic acids with furan-2-carbohydrazide. It was found that substituted 2-[2-(furan-2-carbonyl)hydrazinylidene]-4-oxobutanoic acids undergo intramolecular cyclization in the presence of propionic anhydride to form the corresponding substituted 2-[2-(furan-2-carbonyl
