Copper-Catalyzed Borylacylation of Activated Alkenes with Acid Chlorides

A method for the copper-catalyzed borylacylation of activated alkenes is presented. The reaction involves borylcupration of the alkene, followed by capture of the generated alkyl-copper intermediate with an acid chloride. The reactions operated with low catalyst loading and generally occurre within 15min at room temperature for a range of activated alkenes. In the case of vinyl arenes, enantioselective borylacylation was possible.
