  Two methods of preparation have been proposed and the synthesis has been effected of a large series of beta-N-acylhydrazides of 1-R-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylic acids. The possibility of using various condensing agents for converting them into the corresponding 1,3,4-oxa-diazoloquinolines has been studied. Results are given of an investigation of the antitubercular activity of the synthesized compounds.

  A synthesis and study of the spatial structure of 3-acetyl-4-hydroxy-2-oxo-1,2-dihydroquinoline have been carried. 1-R-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylic acids [1-(4-hydroxy-2-oxo-1,2-dihydroquinolin-3-yl)ethylidene]hydrazides were prepared from this compound by two routes. A comparative analysis of the antitubercular properties of the synthesized compounds and of the closely structurally related N,N'-di(1-R-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carbonyl)hydrazines has been performed.

  Alkylidenehydrazides have been synthesized by the reaction of 1-R-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylic acid hydrazides with lower dialkyl ketones in order to reveal a structure-antitubercular activity relationship. It was shown by H-1 NMR spectroscopy that hydrazones obtained from the unsymmetrical ketone-methyl ethyl ketone-exist primarily in the E-isomer form. It was found that the presence of two aliphatic substituents in the alkylidene fragment of the compounds investigated leads to a marked lowering of antimicobacterial properties.
