Aza-Wacker-Type Reaction between Electron-Deficient Olefins and N-Alkylsulfonamides

“…In addition, the allylic amination of olefins with sulfonamides was reported by several groups . Although significant progress of intramolecular aza-Wacker reaction has been achieved recently, however, the same reaction with sulfonamides in an intermolecular way is less explored . Therefore, the investigation of an efficient catalytic system for this reaction is highly desirable.…”
