  Synthesis of pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidines

  摘要：

  Starting from 1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-ones, a synthesis pathway to the tricyclic pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidines is described. Reaction of 1,5-dihydro-4H-pyrazolo[3,4-d] pyrimidin-4-ones with phosphoryl chloride afforded the corresponding 4-chloro-1H-pyrazolo[3,4-d]pyrimidines. Treatment of these compounds with hydrazine hydrate at reflux temperature gave the hydrazino derivatives, which were subsequently cyclized to the titled compounds on heating with orthoesters in ethanol.

  In the presence of 1, 3-dimethylimidazolium iodide (1), 6-chloro-9-phenyl-9H-purine (7) and 4-chloro-5, 6-dimethylpyrrolo[2, 3-d]pyrimidines 40-42 undrwent uncleophilic aroylation with arenecarbaldehydes (5) to give the corresponding fused aroylpyrimidines 8 and 43-45. 1, 3-Dimethylbenzimidazolium iodide (2) was an effective catalyst for the similar synthesis of 7-aroyl-3-phenyl-3H-1, 2, 3-triazolo[4, 5-d]pyrimidines 16-21. In the synthesis of 4-aroyl-1H-pyrazolo[3, 4-d]pyrimidines 26-32, both azolium salts 1 and 2 were effective as catalysts. Moreover, 4-aroyl-7H-pyrrolo[2, 3-d]pyrimidines 43-45 were obtained in good yields via the 4-tosyl derivatives, in the presence of catalytic amounts of sodium p-toluenesulfinate (46) and the imidazolium salt 1. This catalytic aroylation was found to be a facile and useful method for the synthesis of 6-aroyl-9H-purines and their analogues.

  pyrazolo[3,4-d]pyrimidines tethered with nitric oxide (NO) producing functionality was designed and synthesized. Sulforhodamine B (SRB) protein assay revealed that NO releasing moiety in the synthesized compounds significantly decreased the cell growth more than the des-NO analogues. Compounds 7C and 7G possessing N-para-substituted phenyl group, released the highest NO concentration of 4.6% and 4.7%
