Synthesis of Some Substituted Pyrazolopyrimidine Derivatives: An Environmentally Benign Approach

Pyrazolopyrimidines constitute a medicinally important class of heterocyclic compounds. Herein, we report an efficient and environmentally benign method for the synthesis of pyrazolo[3,4-d]pyrimidin-3-ones from 2,4-dinitrophenylhydrazine and diethyl malonate under microwave irradiation in 1,3-dibutylimidazolium bromide ionic liquid. The synthesized compounds were analyzed by elemental analysis and standard spectroscopic techniques. The compounds were screened for their antibacterial and antifungal activities.

Simple route to a novel class of pyrazolidine-3,5-dione based azo dyes

We report an easiest synthesis strategy of a new class of synthetic dyes by coupling of functionalized pyrazolidine-3,5-dione derivatives via diazotization reaction with aromatic diamine for the azoic dyes or via dimerization reaction to synthesize the H chromophore dyes. Electron delocalization between the two coupled components has been studied using UV-vis spectroscopy, infrared, and NMR spectroscopy. In addition, the formation mechanism of such compounds has been discussed.
