Magnetic Nanoparticles‐Supported Synthesis of Pyrazole Scaffolds: A Review

Abstract In the present era, the concept of green in organic synthesis has a unique and irreplaceable place. Specifically, nanoparticle has gained much more attention due to its various properties related to the concept of green chemistry. In this context, magnetic nanoparticle has been widely used in the organic synthesis over last one decade. Among organic compounds, pyrazole and its scaffolds are recognized as a privileged structure as it represents a promising area for identification of lead structures towards the discovery of new synthetic drug molecules and other valuable candidates. Several commercial drugs such as Sildenafil, Rimonabant, Celecoxib and many other compounds in biological testing and preclinical evaluation, illustrate the wide therapeutic spectrum in this class of drug scaffolds. Accordingly, the magnetic nanoparticles have an irreplaceable place in the synthesis of pyrazole derivatives and it is a green and easy methodology to the organic chemists. The present manuscript represents the assimilation of literature pertaining to green aspects of magnetic nanoparticles for the synthesis of highly diversified and valuable derivatives of pyrazole.
