  名称：

  4-Hydroxy-2-quinolones 171*. Synthesis, isomerism, and antitubercular activity of 1-R-4-hydroxy-2-oxo-1,2-dihydro-quinoline-3-carboxylic acid alkylidenehydrazides

  摘要：

  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.
