DFT Study and Synthesis of Novel Bioactive Bispyrazole using Mg/Al-LDH as a Solid Base Catalyst

Conclusion: In summary, the pharmacologically interesting bis-pyrazole derivatives were synthesized through Mg/Al-LDH as a solid base catalyst, in THF as a solvent. The synthesized bioactive compounds containing the pyrazole ring may have important biological activities and thus can serve as good candidates for pharmaceutical applications. Therefore, the catalyst Mg/Al-LDH showed high catalytic activity. Besides, a series of bispyrazole molecules were synthesized with a good yield and easy separation of the catalyst by simple filtration. Moreover, DFT calculations and reactivity indexes were used to explain the selectivity of the condensation reaction between aryl benzaldehyde and 1,3-diketo-N-phenylpyrazole via Knoevenagel reaction, and the results were in good agreement with the experimental finding.
