The Cu-catalyzedasymmetric conjugate addition of trialkenylboroxines to enonediesters is reported. This operationally simple and scalable reaction proceeded at room temperature, and a wide range of enonediesters and boroxines were tolerated under the applied reaction conditions. The practical utility of this approach was demonstrated via the formal synthesis of (+)-methylenolactocin. Mechanistic
