Synthesis of Thiazole Derivatives as Antimicrobial Agents by Green Chemistry Techniques
Journal of the Turkish Chemical Society, Section A: Chemistry, 2018 Amine (2) and (26) was obtained from the condensation of the corresponding amines with 3,4-difluoronitrobenzene. The reduction of nitro group produced the corresponding amines (3 and 27).

Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis
Chemistry – A European Journal, EarlyView.We demonstrate a sustainable strategy for pharmaceutical manufacturing by combining hydrogen, heterogeneous catalysis, and continuous flow synthesis. The development of novel catalysts and their application in a multi‐step synthesis of donepezil enabled a highly productive process with no intermediate purification.

Chemistry – A European Journal, EarlyView.ABSTRACT We explored aryl thianthrenation as a tool for directly incorporating multiple isotopes into molecular scaffolds starting from full isotopically labeled benzene. Stable isotope‐labeled (SIL) molecules are indispensable tools for investigating chemical and biological mechanisms and quantifying metabolites.

Chemistry – A European Journal, EarlyView.5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Generation of a Ground‐State Electron Donor Utilizing Stored Light Energy
Chemistry – A European Journal, EarlyView.Chemically stored light energy enables the generation of dianion reductants (∼−2.7 V) from vicinal diols derived from diaryl ketone photodimerization. These ground‐state electron donors efficiently reduce challenging substrates at room temperature, including aryl bromides, alkyl iodides, and sulfonamides.
