Special Issue Information
Dear Colleagues,
Multicomponent reactions (MCRs) have emerged as a transformative tool in contemporary organic synthesis, redefining strategies for the construction of complex molecular architectures. By enabling the one-pot combination of three or more reactants, MCRs substantially enhance synthetic efficiency while reducing the number of reaction steps and purification procedures. This streamlined approach conserves time and resources, minimizes chemical waste, and aligns closely with the principles of green chemistry and sustainable development.
Among the most prominent examples of multicomponent reactions are the Biginelli, Hantzsch, Mannich, Ugi, Strecker, and Passerini reactions. These well-established strategies provide efficient routes for the rapid assembly of structurally diverse and complex molecules in a single synthetic step, making them indispensable tools in contemporary chemical research.
Recent advances in catalytic systems have significantly expanded the scope and performance of MCRs. The development of metal-based, enzymatic, and nanoparticle catalysts has improved both reaction efficiency and selectivity. In particular, innovative catalytic approaches involving pincer ligands and magnetic nanoparticles have demonstrated considerable potential in enhancing reaction outcomes while maintaining sustainability. Moreover, emerging strategies such as supramolecular catalysis and mechanochemical techniques continue to open new avenues for the optimization and diversification of multicomponent processes.
The impact of MCRs is especially pronounced in drug discovery, where the rapid generation of large and diverse compound libraries is critical for the identification of novel lead structures. By employing simple and readily accessible starting materials, MCRs facilitate efficient exploration of the chemical space, thereby increasing the likelihood of discovering biologically active compounds. Their high atom economy, operational simplicity, and adaptability further contribute to their widespread application in pharmaceutical research.
Indeed, MCRs play a fundamental role in the synthesis of a broad spectrum of therapeutically relevant agents, including calcium channel blockers (e.g., nifedipine), antiviral drugs (e.g., indinavir and telaprevir), anticancer agents (e.g., ivosidenib), anticonvulsants (e.g., lacosamide), and anthelmintic drugs (e.g., praziquantel).
Thus, the versatility, efficiency, and sustainability of multicomponent reactions underscore their central importance in advancing medicinal chemistry and the development of innovative pharmaceuticals.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
