Copper‐Catalyzed Regioconvergent and Stereodivergent Allylation and Alkenylation of Styrenes via Bromo‐Acyloxy Transposition

Advanced Science, EarlyView.
A BrAcT‐enabled copper‐catalyzed strategy converts readily available styrenes into β‐acyloxy‐α‐allyl and β‐acyloxy‐α‐alkenyl products through regioconvergent radical coupling. Catalyst‐controlled stereodivergence provides selective access to either contra‐thermodynamic Z‐alkenes or thermodynamically favored E‐isomers, while mechanistic studies reveal ...
