as mediator results in fast and efficient cyclization with formation of a substituted 3-azabicyclo[3.1.0]hexane system in 80–98%. The fast (30 min) electrocatalytic reaction proceeds smoothly under neutral and mild conditions. The use of electrocatalysis in a cascade cyclization reaction is an efficientapproach to the medicinallyrelevant 3-azabicyclo[3.1.0]hexane scaffold avoiding the inconvenient
