Abstract:
Background: In synthetic and medicinal chemistry, multi-component reactions (MCRs)
are considered an essential tool in synthesizing bioactive heterocyclic scaffolds. These reactions have
been strategically used in drug discovery and development because of ease and economy.
Objective: The current manuscript aims to highlight the importance of the Biginelli reaction in the
synthesis of diverse dihydropyrimidinones with medicinal applications.
Methods: We searched various keywords, including “multicomponent reaction”, “Biginelli reaction”
and “dihydropyrimidinone” on “PubMed, PubChem, and google scholar” and collected the relevant
articles for including the current work.
Results: Biginelli reaction involving ketoester, aldehyde, and urea is a high-yielding, atomeconomical,
environmentally benign reaction for developing a library of new dihydropyrimidinones
to drive the process of drug discovery. Several developments were achieved with modifications of
synthetic techniques, including C-H activation, coupling, cycloaddition, etc. Inclusively, these modifications
give access to a wide range of dihydropyrimidinones.
Conclusion: The current review provides an overview of recent developments in the Biginelli reaction
and insights into synthesizing bioactive dihydropyrimidinones.
