Nickel‐Catalyzed Three‐Component Difluoroalkylation‐Amination for the Direct Access to Anti‐Inflammatory β‐Difluoroalkyl Amines

Advanced Science, EarlyView.
A nickel‐catalyzed three‐component reductive fluoroalkylation‐amination strategy of N‐vinylamides for the direct access to the α‐amidyl‐β‐difluoroalkyl amines was reported here. The synthetic method features with broad substrate scope, mild conditions, high functional group tolerance, and convenience to handle.

Electrocatalytic Polarity Inversion of Azlactones: Access to α‐Quaternary Amino Acids with Electron‐Rich SOMOphiles

Angewandte Chemie, EarlyView.
Electrocatalytic polarity inversion of azlactones unlocks their coupling with electron‐rich reaction partners. Triarylamine‐mediated oxidation of the azlactone enolate generates an electrophilic radical intermediate that undergoes selective C4 functionalization with diverse SOMOphiles.
