Synthesis of pyrazole and pyrazoline derivatives of β-ionone: Exploring anti-inflammatory potential, cytotoxicity, and molecular docking insights

open access: yesEuropean Journal of Medicinal Chemistry Reports
In the present paper, pyrazole and pyrazoline derivatives of β-ionone were synthesized. The protocol involved intramolecular oxidative C–H amination of hydrazone to yield corresponding pyrazole in moderate to good yields.
