The synthesis of various polycyclic systems containing aC3a–Ni bond between a hexahydropyrrolo[2,3-b]indole and an indole tryptophan is described here. A series of experiments were performed to determine the best combination of five orthogonalprotectinggroups and the best reaction conditions for formation of said bond, which is a common feature among many recently discovered marine natural products
