Photooxidation of 18‐Carbon Polyunsaturated Fatty Acids to Prepare Mono‐Hydroxylated Octadecanoids

Lipids, EarlyView.
We developed a fast and simple one‐step synthetic strategy to produce mono‐hydroxylated metabolites based on the photosensitized oxidation of 18‐carbon polyunsaturated fatty acids (PUFAs). This approach could likely be extended to other PUFAs, suggesting that photosensitized oxidation could be employed to rapidly prepare hydroperoxides from multiple ...

Enantioselective desymmetrization strategy of prochiral 1,3-diols in natural product synthesis

Beilstein Journal of Organic Chemistry
Enantioselective desymmetrization is employed as a powerful tool for the creation of chiral centers. Within this scope, the enantioselective desymmetrization of prochiral 1,3-diols, which generates chiral centers by enantioselective functionalization of ...

Implications of Chiral Signatures of PCBs in Soil, Outdoor and Indoor Air in the West Midlands Conurbation, UK [PDF]

Introduction: In a previous paper1, we presented initial results from a study determining chiral signatures of PCBs 95, 136 and 149 in both outdoor air collected using passive air samplers, and topsoil from a number of urban, rural and semi urban ...

Integrated Reaction Monitoring and In Situ Structural Elucidation of Reactive Intermediates With Time‐Resolved NOAH NMR Supersequences

Magnetic Resonance in Chemistry, EarlyView.
TR‐NOAH‐NUS enables real‐time reaction monitoring and direct structural characterization of transient intermediates. Integration of NOAH supersequences with t0‐filling minimizes reaction monitoring deadtime and provides high temporal resolution for kinetic analysis.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Molecularly Engineered 2D Xene Heterostructures With Implanted Peroxidase‐Like Activity for Mimicking Enzyme Functions

Small Methods, EarlyView.
A modular electropolymerization strategy is used to covalently graft a vinyl‐terminated Co(II) molecular catalyst onto allyl 2D germanane. This molecular programming approach yields a 2D Xene nanozyme with implanted peroxidase‐like activity, enabling sensitive and selective electrochemical detection of hydrogen peroxide and the monitoring of ...

Ligand‐Controlled Tunable Distal C(sp2)–H Functionalization of Aryl and Benzyl Phosphonates

Transformative Chemistry, EarlyView.
The switchable borylation of aryl and benzyl phosphonates with good to excellent regioselectivity was demonstrated. Through orthogonal transformation of Horner–Wadsworth–Emmons olefination and Suzuki–Miyaura cross coupling, a variety of styrene derivatives were obtained with precise site control.

Crystal structure of the plant GABA aminotransferase AtGABA‐T from Arabidopsis thaliana

Acta Crystallographica Section F, EarlyView.
The crystal structure of A. thaliana γ‐aminobutyric acid aminotransferase (GABA‐T) reveals that plant GABA‐T belongs to the class III aminotransferase family and employs a C‐terminal arginine residue for γ‐aminobutyric acid recognition, in contrast to the N‐terminal arginine used by class II enzymes.γ‐Aminobutyric acid aminotransferase (GABA‐T) is a ...
