Etidronic Acid Catalyzed Efficient Synthesis of 1H-imidazo[1,2-b] pyrazole via Sequential One-pot Strategy

Authors(2) :-Dr. Jayesh Babariya, Dr. Yogesh T. Naliapara

In present work we report a convenient and efficient synthesis of 1H-imidazo[1,2-b]pyrazole library by multicomponent reaction of 2-cyano-N-cyclohexyl-3,3-bis(methylthio)acrylamide, hydrazine hydrate, aldehyde and tert-butyl isocyanides. Here 2-cyano-N-cyclohexyl-3,3-bis(methylthio)acrylamide was synthesized by condensation reaction of ethylcyanoacetate and cyclohexylamine in toluene at reflux temperature and followed by reaction with CS2 in DMF in presence of potassium carbonate at room temperature. The newly synthesized compounds were characterized by IR, Mass, 1H NMR, 13C NMR spectroscopy and elemental analysis. All the synthesized compounds were evaluated for their antimicrobial activity. The investigation of antimicrobial and antifungal screening data revealed that all the tested compounds showed moderate to significant activity.
