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