β‐Amino Acid Synthesis Using the CO2 Radical Anion under Electrochemical and Photochemical Conditions

ChemistryEurope, EarlyView.
The development of sustainable methods for synthesizing β‐ and γ‐amino acids is crucial due to their significance in pharmaceuticals and materials science. This study introduces a novel strategy employing the CO2 radical anion as a key intermediate to access these amino acids from N‐Ac‐enamides and N‐Ac‐allylamines.

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 ...
