Special Issue Information

Dear Colleagues,

This Special Issue is devoted to the fascinating topic of multicomponent reactions (MCRs). These reactions are a group of powerful and highly convergent chemical transformations capable of generating enormous structural diversity by reacting three or more starting materials simultaneously. These reactions utilize subtle differences in reactivity between various functional groups to allow a predictable series of reactions to occur in the same vessel, leading to the formation of the desired product. Furthermore, the product incorporates the vast majority of atoms from all starting materials in its framework, making MCRs inherently efficient and sustainable processes. There has been a tremendous amount of interest in MCRs over the last few decades and, as the demands for new and sustainable materials and medicines continue to increase, the topic will undoubtedly remain a focal point for synthetic chemists around the world.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Molbank is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 500 CHF (Swiss Francs). 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.

Abstract
Dihydropyrimidine derivatives possess great potential to be used as a precursor for the synthesis of wide diverse dihydropyrimidine-like derivatives. In this research, the title compounds were synthesized through the reaction between 5-acetyl-4-(2,5-dimethoxyphenyl)-6-methyl-3,4-dihydropyrimidin-2(1H)-thione and 2,5-dimethoxybenzladehyde under aldol condensation condition. The title compound, [...] Read more.

N-aminorhodanine as well as isatin are highly solicited motifs known for their wide potential for biological activity. The objective of this work was to synthesize hybrid molecules as kinase inhibitors from these two motifs. In order to study the reactivity of the two active centers in aminorhodanine (N-amino group and the 5-methylene group) toward two carbonyl groups (aromatic aldehyde and ketone of isatin), we decided to carry out a one-pot multi-component reaction by simultaneously introducing aminorhodanine, isatin, and an aromatic aldehyde in ethanol in the presence of AcOEt. Under these conditions, this reaction led to a single adduct. The reaction product structure was confirmed by 1H, 13C-NMR, X-ray single crystal analysis, and high-resolution mass HRMS analysis. As a result, the method used has been very effective and totally stereo- and regioselective. Full article

Abstract
The Biginelli reaction is a highly versatile reaction that leads to dihydropyrimidinones/thiones. This scaffold is reported as being a privileged structure due to its ability to interact with biological targets. Synthesis of ethyl 4-(2-fluorophenyl)-6-methyl-2-thioxo-1-(p-tolyl)-1,2,3,4-tetrahydropyrimidine-5-carboxylate was achieved through the Biginelli reaction using [...] Read more.
The Biginelli reaction is a highly versatile reaction that leads to dihydropyrimidinones/thiones. This scaffold is reported as being a privileged structure due to its ability to interact with biological targets. Synthesis of ethyl 4-(2-fluorophenyl)-6-methyl-2-thioxo-1-(p-tolyl)-1,2,3,4-tetrahydropyrimidine-5-carboxylate was achieved through the Biginelli reaction using a functionalized thiourea. In silico studies demonstrated that the compound title showed good potential for interacting with ecto-5’-nucleotidase, which has been considered as a target in designs for anti-cancer drugs.
