les in the presence of anhydrous ZnCl2 to give functionalized 2-pyrrolo-3′-yloxindoles in satisfactory yields, which can be further converted to the corresponding 6,11-dihydro-5H-indolizino[8,7-b]indoles in good yields through a CF3SO3H catalyzed Pictet–Spengler cyclization process. Under similar conditions, when arylamines were used to replace tryptamine, the one-pot domino reaction afforded the functionalized
