A collective asymmetric total synthesis of marine tricyclic alkaloids, cylindricines A-H, as well as the proposed structures of cylindricines I and J, was accomplished from a single common spirocyclic pyrrolidine intermediate in a concise manner. A tandem chemoselective oxidation/intramolecular aza-Michael addition/epimerization strategy was utilized to successfully construct the tricyclic skeleton. This work presents a versatile synthetic approach to the cylindricine family of marine tricyclic alkaloids.
