A hypervalentiodine-mediated intermolecular α-umpolung reaction between α-aryl- or alkyl-substituted amides and benzotriazoles or purine derivatives as N-centered nucleophiles has been established. The reaction involves sequential intra/intermolecular oxidative C–N couplings in a controlled manner, affording tetrasubstituted 3,3′-oxindoles in moderate to good yields. This approach efficiently addresses
