A Simple and Efficient Microwave Assisted Synthesis of Pyrazolo [3,4-D] [1,2,4] Triazolo [1,5-A] Pyrimidines
Keywords:
Pyrazolo[3,4-d][1,2,4]triazolo[1,5-a]pyrimidines; planar heterocyclic ring systems; catalyst-free; one-pot: Biginelli like cyclocondensationAbstract
With the aim to extend the synthetic pathways to new planar heterocyclic ring systems, synthesis of pyrazolo[3,4-d][1,2,4]triazolo[1,5-a]pyrimidine, a new ring system, was achieved by using a one-pot, microwave-assisted, catalyst-free, Biginelli like cyclocondensation reaction. All the newly synthesized were characterized by various spectrometric techniques like FT-IR, mass spectra, 1H NMR, 13C NMR and elemental analysis.
