Development of an Organoautocatalyzed Double σ‐Bond C(sp2)‐N Transamination Metathesis Reaction
Angewandte Chemie, EarlyView.Organoautocatalyzed transamination metathesis of cyclic tertiary amines is disclosed as a high‐yielding, scalable reaction that proceeds under mild, catalyst‐free conditions. It operates via a multi‐step domino reaction mechanism, where an in situ‐formed pyrrolidinium salt functions as a HBD organoautocatalyst.

Reverse Regioselective Dicarbofunctionalization via Anti‐Michael‐Type Addition
Angewandte Chemie, EarlyView.A reverse regioselective dicarbofunctionalization of acrylamides via anti‐Michael‐type addition is reported. Various (hetero)arene nucleophiles and carbon electrophiles were incorporated in a manner opposite to conventional regioselectivity. A key feature of this reaction is the formation of an alkylpalladium intermediate, which enables the achievement
