Towards the Sustainable Synthesis of Biologically Active Molecules in Green Solvents

Topic Information

Dear Colleagues,

Over the past decades, sustainability has become an imperative issue. In the field of organic synthesis, both academic and industrial scientists are making efforts to develop more environmentally friendly chemical processes. In the manufacturing, chemical, and pharmaceutical industries, the solvents employed in synthetic methodologies represent 75–80% of the total waste generated. Indeed, the demand for sustainable alternatives that can replace hazardous solvents has become a subject of intense research today. It could be possible to reduce the environmental impact of chemical transformation through the choice of a suitable solvent, such as through the employment of green solvents derived from renewable sources. This Special Issue plans to give an overview of the most recent advances in the field of the sustainable synthesis of biologically active molecules. The issue aims to provide selected contributions on advances in the preparation of bioactive compounds in green solvents, such as deep eutectic solvents (DES), alcohols and polyols, supercritical CO₂, etc. Potential topics include, but are not limited to: Synthetic methodologies with a low environmental impact; The green synthesis of heterocycles; The more eco-friendly synthesis of compounds with possible applications in the biological pharmacological field; The synthesis of organic compounds in deep eutectic solvents; The synthesis of organic compounds in green alcohols; Synthetic strategies in supercritical CO₂.

Abstract

A new allyl derivative of curcumin containing three allyl groups (1E,6E)-4-allyl-1,7-bis(4′-allyloxy-3′-methoxyphenyl)hepta-1,6-diene-3,5-dione was synthesized by the reaction of curcumin with the excess of allyl bromide in the presence of K₂CO₃ in acetone under reflux. The triple-allylated curcumin [...] Read more.

Nitrothiazole derivatives have been reported to exhibit activity against aerobic, anaerobic, and microaerophilic bacteria. This activity profile makes the nitrothiazole compound class an ideal lead source against Mycobacterium tuberculosis, which flourishes in varied environments with different oxygen concentrations. In this work, we investigated six nitrothiazole derivatives for antitubercular activity. The compounds exhibited potent activity, with compounds 9 and 10 possessing an equipotent MIC₉₀ value of 0.24 µM. The compounds were investigated for cytotoxicity against HEK293 cells and hemolysis against red blood cells, and they demonstrated no cytotoxicity nor hemolytic effects, suggesting they possess inherent antitubercular activity.

A novel single crystal of (3-(4-chlorophenyl)-4,5-dihydroisoxazol-5-yl)methyl benzenesulfonate has been synthetized via a one-pot sequential strategy under sonication. The single crystal has been investigated using X-ray diffraction analysis. Hydrogen bonding between C–H···O and C–H···N produces a layer structure in the crystal. According to a Hirshfeld surface analysis, interactions H···H (28.9%), H···O/O···H (26.7%) and H···C/C···H (15.8%) make the largest contributions to crystal packing. The optimized structure and the solid-state structure that was obtained through experiments are compared using density functional theory at the B3LYP/6-311 G + (d,p) level. The computed energy difference between the lowest unoccupied molecular orbital (LUMO) and highest occupied molecular orbital (HOMO) is 4.6548 eV. Full article

In this work, a new compound, 2-(N-allylsulfamoyl)-N-propylbenzamide, has been synthesized via a tandem one-pot reaction under sonication. The rotational orientations of the allylsulfamoyl and the amide groups in the title molecule, C₁₃H₁₈N₂O₃S, are partly determined by an intramolecular N—H···O hydrogen bond. In the crystal, a layer structure is generated by N—H···O and C—H···O hydrogen bonds plus C—H···π (ring) interactions. A Hirshfeld surface analysis indicates that the most important contributions to crystal packing are from H···H (59.2%), H···O/O···H (23.5%), and H···C/C···H (14.6%) interactions. The optimized structure calculated using density functional theory at the B3LYP/6–311 G (d,p) level is compared with the experimentally determined structure in the solid state. The calculated highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy gap is 5.3828 eV. Full article
