A series of Schiff base derivatives 4a-k were synthesized from 4-amino-3-(4-pyridyl)-5-mercapto-
4H-1,2,4-triazole 3 as starting materials by using microwave irradiation technique. The synthesized
compounds were fully characterized by NMR, FT-IR, elemental analysis, and HR-mass spectra. The
results indicated that the microwave irradiation technique gave higher yields of pure products with
short time of the reaction in compare to the thermal method.
A thalidomide analog, (4‐(1,3‐dioxo‐1,3‐dihydro‐2H‐isoindol‐2‐yl)‐N′‐[(4‐ethoxyphenyl)
methylidene] benzohydrazide), has been identified as a promising broad‐spectrum anti‐inflammatory…
A new series of 3,4,5-trimethoxyphenyl bearing
pyrazole (4a–g) and pyrazolo[3,4-d]pyridazine (5a–g)
scaffolds were synthesized in good yield. The newly synthesized
compounds were…
