Unsaturated ϵ-lactams undergo a novel process involving a skeletal reorganization to give fused pyrrolidine-lactones by reaction with aromatic α-bromo ketones in the presence of 1,4-diazabicyclo[2.2.2]octane and a base. The process involves the formation of an ammonium salt and subsequently a nitrogen ylide, which initiates the rearrangement reaction. This species reduces undesired side-reactions such
