Characterization of the Volatile Compounds of the Hardwood Portion of Betula papyrifera Marshall From Quebec, Canada

open access: yesChemistry &Biodiversity, EarlyView.
The volatile profile of Betula papyrifera hardwood has been characterized using both hydrodistillation and HS‐SPME coupled with GC‐MS/FID. Hydrodistillation yields a fatty acid‐rich essential oil, while HS‐SPME reveals a broader range of low‐molecular‐weight volatiles, including aromatics and terpenoids.

A Thermostable Fatty Acid Hydratase from Marinitoga Piezophila with Low Temperature Optimum and Broad Product Scope

open access: yesChemBioChem, EarlyView.
A rare thermostable Fatty Acid Hydratase ortholog from Marinitoga Piezophila, a thermo‐piezophilic organism, displays novel properties. While the enzyme has excellent thermostability (retaining full activity after incubation at 70°C), quite interestingly, it shows the highest activity at 20 °C. Moreover the enzyme has a broad substrate scope and unique

Diastereoselective, Diversifiable Synthesis and Biological Evaluation of the Virginiamycin Inducers, the Virginiae Butanolides

open access: yesChemBioChem, EarlyView.
Production of natural products is tightly regulated, resulting in many silent biosynthetic gene clusters. BarA is a repressor that downregulates production of the virginiamycin antibiotics. The VBs are ligands for BarA that reverse its repression of virginiamycin production.

Advancing Light‐Triggered Alkyd Paint Curing: (Cp)FeII(naphthalene)](PF6) Catalysts with Enhanced Photosensitivity and Increased Performance in Pigmented Alkyd Paints

open access: yesChemistryEurope, EarlyView.
[(Cp)FeII(naphthalene)](PF6) catalysts are reported with improved curing efficiency of alkyd paints compared to [(Cp)FeII(arene)](PF6), particularly in dark‐pigmented formulations. Their improved photosensitivity enables faster drying at lower concentrations, presenting a promising alternative to conventional industrial driers under regulatory pressure.

Photocatalytic Decarboxylative Functionalization of Bioactive, Naturally Occurring, and Fatty Acids Via Gem‐Borylsilyl Alkene

open access: yesChemistryEurope, EarlyView.
A photocatalytic, late‐stage decarboxylative functionalization of carboxylic acids using gem‐borylsilyl alkenes is described. This transformation enables the direct decarboxylative /radical addition of bioactive, naturally occurring, and fatty acids to gem‐B,Si alkenes, delivering synthetically valuable alkylboron,silayl under mild, visible‐light ...
