The Dithiirane–Thiosulfine Equilibrium Revisited—A Computational Study of Structure, Thermodynamics and Kinetics

Journal of Physical Organic Chemistry, Volume 39, Issue 6, June 2026.
The dithiirane–thiosulfine equilibrium has been revisited by means of modern computational chemistry tools to shed light on whether stable thiosulfines might be isolated. ABSTRACT Thiosulfines as reactive S‐centered 1,3‐dipoles undergoing (3 + 2)‐cycloadditions are still of interest in the chemistry of sulfur‐rich heterocycles.

The interplay between the pyramidalization of carbonyl carbons and the n → π* interactions in biomolecules

Protein Science, Volume 35, Issue 6, June 2026.
Abstract The structural preferences of biomolecules arise from a delicate balance of different forces whose identification and quantification are challenging. Studies conducted over the last two decades have shown that the n → π* interaction formed between consecutive carbonyl groups plays a crucial role in stabilizing biomolecules, which exhibit a ...

Allosteric Regulation of RNA Affinity by Motif V‐VI Coupling in West Nile Virus NS3 Helicase

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 6, Page 1212-1224, June 2026.
ABSTRACT The rise of flaviviral diseases, including West Nile virus (WNV), presents a growing threat to global public health and underscores the urgent need for new therapeutic strategies. The non‐structural protein 3 helicase (NS3h) of the Orthoflavivirus genus, including WNV, is essential for viral replication and a promising antiviral target ...

Stereoselective Synthesis of Glycomimetic Amines From Biomass‐Derived Cyrene

European Journal of Organic Chemistry, Volume 29, Issue 18, 14 May 2026.
2,3,4‐Trideoxy‐2‐mannosamines, including the unsubstituted one, are accessible as the only endo diastereoisomers by reductive amination of the green solvent Cyrene, derived from pyrolysis of cellulose containing waste biomass. The products are useful chiral synthetic intermediate to nitrogenated glycomimetics.

Two‐Stage, Sequential Aryne Carboiodanation Enabled by Mesomeric Priming

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Two‐stage, sequential insertion of arynes into the carbon–iodine(III) bond of benziodoxole (BX) compounds is achieved by judicious choice of the BX/aryne pair in the first step, generating a mesomerically activated aryl‐BX primed for a second, discrete aryne insertion. This metal‐free strategy enables programed access to biaryl‐BXs and modular entry to
