spirocyclic 2‐oxindoles containing the α‐methylene‐γ‐butyrolactam structure via “electrophilic amide allylation” is reported. The key reaction was accomplished by using acetoxy methacrylamides and tetrakis(triphenylphosphine)palladium as catalyst, affording a variety of the amide allylated products in excellent yields.
