Intramolecular oxidative coupling of tryptamine incorporated amide was used to create the quaternary spiroindoline carbon center of communesins, which enabled a short asymmetric synthesis of (-)-communesins A and B and F. The fused tetra-ring framework of Vincorine was established by an intramolecular oxidative coupling/condensative cyclization process, which was further advanced to (-)-vincorine in 5 steps. From a medicinal standpoint, such a cascade process provides a highly diverse, efficient method for the construction of polycyclic spiroindoline scaffolds. Starting from easily accessible tryptamine incorporated β-ketoamides and malonamides, polyclic spiroindolines and pyrroloindolines could be directly obtained by adopting the same cascade strategy.

Key words: intramolecular oxidative coupling, indole alkaloids, total synthesis, polycyclic spiroindoline, pyrroloindoline
