“Innocent” Electrolytes Can Influence Organic Electrosynthetic Selectivity

ChemElectroChem, Volume 13, Issue 14, 17 July 2026.
Organic electrosynthesis has emerged as a powerful strategy for leveraging inexpensive and abundant electricity in organic synthesis, but understanding the role of inert supporting electrolyte is largely unexplored. This article investigates cobalt‐based metal–carbon bond homolysis and elucidates how supporting electrolytes influence reaction rates ...

Sustainable Synthesis of Bio‐Based Furanic and Aromatic Amines Using an Optimized Whole‐Cell Transaminase–Decarboxylase Cascade in E. coli RARE

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
A whole‐cell biocatalytic cascade in engineered Escherichia coli RARE couples the ω‐transaminase from Pseudomonas psychrotolerans with pyruvate decarboxylase from Zymomonas mobilis to shift transamination toward amine formation via pyruvate removal. Integration of the cascade into a chemo‐enzymatic synthesis pathway enables the scalable production of 2,

Fluorinated Aminopiperidones as Non‐Glutarimide Thalidomide Analogs: Stereodivergent Synthesis and Validation

ChemMedChem, Volume 21, Issue 13, 14 July 2026.
Fluorinated aminopiperidones, designed as non‐glutarimide thalidomide analogs, were synthesized with full regio‐ and stereocontrol. The C*–CF3 used as carbonyl surrogate improved solubility and membrane interactions while abolishing cereblon binding.

Enzyme–MOF Composites: Quantitative Benchmarking and Evaluation of Biocatalyst Performance

Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
Rigorous evaluation of enzyme@MOF composites requires quantitative benchmarking. This study illustrates this approach by applying and comparing enzyme‐loading and activity‐assessment strategies for two structurally and functionally distinct enzymes, phenolic acid decarboxylase, and cytochrome c.

Application of Ibuprofen Sodium Dihydrate for Thermochemical Energy Storage

Advanced Functional Materials, Volume 36, Issue 53, 2 July 2026.
Ibuprofen sodium dihydrate is introduced as a durable organic salt hydrate for low‐temperature thermochemical energy storage, operating within 60°C–110°C with high energy density. At the material level, it delivers ∼99.9% cycling efficiency over 150 cycles without deliquescence, enabled by a dual energy‐storage mechanism coupling dehydration and phase ...

Studying Phosphoroorganic Modification of Smac‐Mimetics to Boost Selectivity for cIAP1‐BIR3 and Unravel cIAP1/XIAP Molecular Inhibition Mechanisms

Asian Journal of Organic Chemistry, Volume 15, Issue 7, July 2026.
The phosphoroorganic modification of Smac‐mimetics (SMs) drives selectivity for cIAP1‐ over XIAP‐BIR3. The divalent SM 6 partially dimerizes cIAP1, whereas it prefers intramolecular binding in XIAP. In XIAP the phosphoroorganic moiety of the monovalent SM 7 functions as an IBM, thus inhibiting both BIR2 and BIR3. Created in BioRender.
