Curcumin-based bioactive heterocycles derived via multicomponent reactions.

Curcumin is an important phytochemical, found in the Asian countries, especially in the Indian subcontinent. The use of this "privileged natural product" in the diversity-oriented synthesis of curcumin-based heterocycles via multicomponent reactions (MCRs) is the subject of interest for many medicinal chemists across the globe. This review particularly focuses on the reactions involving curcuminoids as one of the reactants in the MCRs of curcuminoid to synthesize curcumin-based heterocycles. Also, the various pharmacological activities of curcumin-based heterocycles generated via the MCR approach are discussed. The research work published in the last 10 years is in the focus of this review article.
