  Two variants are discussed of the synthesis of 1-R-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylic acid beta-N-tosylhydrazides which undergo a McFayden-Stevens reaction to give 1-R-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carbaldehydes in high yields. It was shown that the thiosemicarbazones prepared from them exist in the solid state exclusively in the syn-form while in solution a hydrazone. <-> enhydrazine tautomerism is observed. The results of a study of the antitubercular activity of the synthesized compounds are reported.

  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.
