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 gamma -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.

Pivaloylpyruvic acid is an efficient reagent for preparative acylation of amines. A method for the synthesis of substituted pivaloylpyruvamides with domination of (Z)-β-keto-enol tautomer is proposed. The structure of pivaloylpyruvic acid and its amides, as well as the specific features of the reaction of pivaloylpyruvic acid with amines, are discussed.
