"Dimethyl oxalate (and the related diethyl ester) is used in diverse condensation reactions. For example, diethyl oxalate condenses with cyclohexanone to give the diketo-ester, a precursor to pimelic acid. With diamines, the diesters of oxalic acid condense to give cyclic diamides. Quinoxalinedione is produced by condensation of dimethyloxalate and o-phenylenediamine: " - Diethyloxalate condensation
