developed, allowing various bis(indole) derivatives in good to excellent yields with wide substrate scope, which not only represents the first molecular iodine-catalyzed tandem complex alkyne cycloisomerizations but also constitutes the first chemoselective cycloisomerization of tryptamine-ynamides involving distinctively different C−C (alkyl) bond cleavage and rearrangement.
