Condensation of 4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carbaldehydes, thioglycolic acid ( or methyl thioglycolate), and anilines does not lead to the synthesis of the corresponding thiazolidinylquinolones because the Schiff bases so formed exist exclusively in a form inert to enamine thioglycolates. H-1 NMR spectroscopy showed that the main components of the isolated 3-arylaminomethylenequinoline-2,4-(1H,3H)-diones are E-isomers. The results of a study of the antitubercular properties of the compounds obtained are presented.
