The reaction of esters of β, γ-acetyleneic α-keto acids with o-phenylenediamine (I) leads, in the case of esters of arylethynylglyoxylic acids (II) in an anhydrous solvent solvent, to 2-arylethynyl-3-quinoxalones (III). 2-Phenacyl-3-quinoxalones (IV) are formed when III are treated with alcoholic alkali. The reaction of esters of alkylethynylglyoxylic acids (V) with I leads to 2-(β-oxoalkyl)-3-quinoxalones (VI). The structures of III and VI were confirmed by the IR spectra.
