Herein, we report the synthesis of C3,C4-disubstituted indoles via the palladium/norbornene cooperative catalysis. Utilizing N-benzoyloxy allylamines as the coupling partner, a cascade process involving ortho-amination and ipso-Heck cyclization takes place with ortho-substituted aryl iodides to afford diverse indole products. The reaction exhibits good functional group tolerance, in addition to tolerating
