Angewandte Chemie International Edition, EarlyView.An anomeric amide‐enabled divergent aldehyde functionalization sequence provides one‐pot access to unsymmetrical ureas, carbamates, thiocarbamates, thioesters, and amides. Key to this transformation is the formation of N‐Boc‐hydroxamate intermediates, which serve as platforms for orthogonal activation via Lossen‐type rearrangements, single‐electron ...

Ambident Reactivity in the Phenyl + NO Radical Recombination
Chemistry – A European Journal, EarlyView.ABSTRACT The recombination reaction of nitric oxide (NO) with radicals via its oxygen atom, rather than the more common nitrogen site, offers an intriguing pathway to the formation of oxynitrenes. The photochemical isomerization of nitroso compounds into their corresponding oxynitrenes may involve such a step.
