4-HYDROXY-2-QUINOLONES. 17. DIECKMANN CONDENSATION AS A THERMALLY ACTIVATED PROCESS
The thermolysis of ethyl 2-ethoxycarbonylmalonanilate in boiling diphenyl oxide gave the 2-ethoxycarbonylanilide of 1H-2-oxo-4-hydroxyquinoline-3-carboxylic acid, which is also formed from the N,N'-di-2-ethoxycarbonylaniline of malonic acid in the conditi

Ethyl Esters of Malonanilic Acids. Synthesis and Pyrolysis
The pyrolysis under 170-220 deg C or boiling in DMF of malonanilic acids ethyl esters (2) is accompanied by formation of malonic acids symmetric dianilides (7) with high yields.A possible mechanism for this transformation has been suggested.
