Nitrogen‐Centered Radical‐Directed C(sp3)−H Amination and Aminoalkylation Using (Diarylmethylene)amino Benziodoxolones

ChemistryEurope, EarlyView.
This report describes a C(sp3)−H aminofunctionalization via the photoexcitation of (diarylmethylene)amino benziodoxolones. These iodine reagents act as both single‐electron oxidants and nitrogen‐based SOMOphiles, serving as iminyl radicals, enabling the site‐selective C(sp3)−H amination and aminoalkylation of α‐aminoxy acid derivatives.

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

ChemistryEurope, 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 ...

Synthesis of New N,N′‐Diarylureas and Their Theoretical Study as Cannabinoid‐1 Receptor Inhibitors

ChemPlusChem, EarlyView.
A series of new pyrazolo‐ and triazolo‐based N,N′‐diarylureas is synthesized following the triphosgene protocol in the last step. Density functional theory calculations and molecular docking provide strong evidence that all new compounds bind strongly to the cannabinoid‐1 (CB‐1) receptor, showing comparable results with the known allosteric CB‐1 ...

Novel approach to study fish oil oxidation using 1H nuclear magnetic resonance spectroscopy

Journal of Functional Foods, 2017
The oxidative degradation of omega-3 fatty acids-rich fish oil was investigated by 1H Nuclear Magnetic Resonance (NMR) Spectroscopy. The intensities of key distinct spectral signals corresponding to bis-allylic (RBAG) and terminal methyl groups (RO3TG ...

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...
