  Annulation and Evaluation of Antibacterial Activity of the New Fused Tricyclic (5,5,6) Ring System of Pyrazolo[1,5-c]-1,2,4-triazolo[4,3-a]pyrimidines

  摘要：

  A series of the new fused 5-aryl-8-phenyl-2H-pyrazolo[1,5-c]-1,2,4-triazolo[4,3-a]pyrimidine-3-thiones 2 were prepared in excellent yields by the reaction of 5-aryl-7-hydrazino-2-phenylpyrazolo[1,5-c]pyrimidines 1 with carbon disulfide in the presence of potassium hydroxide. The pyrazolotriazolopyrimidinethiones gave with certain electrophiles the respective 6-substituted 3-thiones 4-6 rather than the 7-substituted isomeric structure 7. Oxidation of 2 with sodium nitrite or benzenediazonuim chloride afforded the corresponding disulfides 9 or 10 respectively. Moreover, the pyrazolotriazolopyrimidinones 8 were prepared upon reaction with alkaline hydrogen peroxide. All the above compounds were evaluated as antibacterial agents against a variety of microorganisms.

  5-Aryl-2-phenylpyrazolo[1,5-c]pyrimidine-7(6H)-thiones have been synthesized by the reaction of 1,5-diaryl-4-pentyne-1,3-diones with thiosemicarbazide and their reactions were studied. The pyrazolopyrimidinethiones give with certain electrophiles the respective 3-substituted 7-thiones. Their oxidation affords the corresponding disulfide. Moreover, they can be converted to the corresponding pyrazolopyrimidinones

  The title compounds have been prepared in excellent yields by the reaction of 5-aryl-2-phenylpyrazolo[1,5-c]pyrimidine-7(6H)-thiones with potassium hydroxide. The reactions of these pyrazolopyridones have been investigated. The ring system readily undergoes electrophilic substitution at the 7-position. They are converted to the corresponding pyrazolopyridinethiones on reaction with phosphorus pentasulfide. The structures of the above compounds were elucidated by their spectral characteristics.
