  4-hydroxy-2-quinolones 165*. 1-R-4-hydroxy-2-oxo-1,2-dihydro-quinoline-3-carbaldehydes and their thiosemicarbazones. Synthesis, structure, and biological properties

  摘要：

  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.
