Synthesis and reaction of 5- [6,6-dimethyl-1-4-oxo4, 5,6,7-teteahydroindol-2-yl] -1,3-diarylpyrazolines

ABSTRACT

A number of 3-[6,6-dimethyl-4-oxo-4,5,6,7-tetrahydroindol-2-yl]-1- aryl-2-propen-1-ones II-V have been prepared and transformed into the corresponding arylhydrazones VI-XI. The latter compounds were cyclized to the pyrazolines XII-XX, which were oxidized the corresponding pyrazoles XXI-XXIV. The spectral properties of the prepared compounds were discussed
