Projected reduction in healthcare costs in Belgium after optimization of iodine intake : impact on costs related to thyroid nodular disease [PDF]

, 2010
Background: Several surveys in the last 50 years have repeatedly indicated that Belgium is affected by mild iodine deficiency. Within the framework of the national food and health plan in Belgium, a selective, progressive, and monitored strategy was ...

Cinnamic‐Hydroxamic‐Acid Derivatives Exhibit Antibiotic, Anti‐Biofilm, and Supercoiling Relaxation Properties by Targeting Bacterial Nucleoid‐Associated Protein HU

Advanced Science, EarlyView.
Cinnamic‐hydroxamic‐acid derivatives (CHADs) are identified as novel inhibitors of the bacterial nucleoid‐associated protein HU, exhibiting potent antibacterial, anti‐biofilm (both inhibition and eradication), and DNA relaxation (anti‐supercoiling) activities. Moreover, CHADs demonstrate strong synergistic effects with multiple antibiotics.

(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications

Angewandte Chemie, EarlyView.
In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

Efficient and Scalable Electrochemical Energy Systems via Peroxide‐Mediated Redox Chemistry

Advanced Science, EarlyView.
We outline reaction mechanisms and catalyst strategies that enable efficient, reversible O2 ⇌ HO2– chemistry. Peroxide‐mediated pathways offer an alternative to the conventional 4e–/O2 route, improving round‐trip energy efficiency in rechargeable zinc–air batteries and supporting scalable hydrogen production without external storage or transportation ...

Divergent Total Synthesis of Denudatine Alkaloids Cochlearenine, Macrocentrine, Dictizine, 15‐Veratroyl‐17‐Acetyl‐19‐Oxodictizine, and the Proposed Structure of Acochlearine

Angewandte Chemie, EarlyView.
An intramolecular Mannich reaction (A/B/E/F rings) and intermolecular Diels–Alder reactions (C/D rings) afforded a cage‐like hexacyclic core skeleton of denudatine alkaloids. Derivatization of the hexacyclic intermediate enabled the first asymmetric total syntheses of four denudatine alkaloids: (–)‐cochlearenine, (–)‐macrocentrine, (–)‐dictizine, and (–

Zwitterionic Electrolyte Additives Empowered Robust Zn–I2 Batteries Enduring a Low Temperature of −40 °C

Advanced Science, EarlyView.
A zwitterionic pyrrole (ZiPy) additive is designed to simultaneously suppress polyiodide shuttling and stabilize the zinc anode in Zn–I2 batteries. ZiPy regulates interfacial pH, optimizes Zn2+ solvation, and promotes (002)‐oriented Zn deposition, enabling outstanding cycling stability over 45 000 cycles and excellent low‐temperature endurance ...

Photothermal Conversion Promotes Challenging SNAr for Facile C─N Bond Formation

Angewandte Chemie, EarlyView.
Photothermal conversion enables facile aromatic C─N bond formation via red light irradiation. A variety of inter‐ and intramolecular SNAr transformations are achieved under mild, schematically simple conditions. Additionally, a thermally promoted halogen exchange mechanism provides access to aryl bromides, chlorides, and fluorides – making this ...

A Generalized Approach for Distal C–H Arylation of Organic Building Blocks: Unveiling the Role of Counter Anion

Advanced Science, EarlyView.
We report a general strategy for meta‐selective C–H arylation using aryl iodides and a Pd(II)/Pd(IV) catalytic system guided by a removable directing group. DFT and experimental studies reveal that counter anion tuning (acetate to trifluoroacetate) significantly enhances selectivity.
