Reactions of acylpyruvic acids and 2,3-dihydrofuran-2,3-diones with 2,3-diaminopyridine

Acylpyruvic acids readily react with 2,3-diaminopyridine to form (Z)-3-acylmethylene-1H-3,4-dihydropyrido[2,3-b]pyrazin-2-ones. 5-Aryl-2,3-dihydrofuran-2,3-diones which can be regarded as lactones derived from γ-enolized aroylpyruvic acids react with 2,3-diaminopyridine under mild conditions, yielding regioisomeric (Z)-2-aroylmethylene-4H-1,2-dihydropyrido[2,3-b]pyrazin-3-ones. The structure of the products and reaction chemoselectivity are discussed.

Synthesis and 13C FT NMR spectroscopy of furan-2,3-dione derivatives

Substituted furan-2,3-diones were obtained by condensation of oxalyl chloride with silyl enol ether of para-substituted acetophenones (R = H, CH3, OCH3, Cl, Br, F), propiophenone, 1-tetralone, 6-methoxytetralone and 1-benzosuberone.The spectroscopic data obtained from IR, UV, 1H and 13C NMR studies are quite similar whichever are the substituents. furan-2,3-dione / 1H and 13C NMR / UV and IR spectra
