An efficient, robust, and scalable strategy to access the functionalized core of calyciphyllineA-typealkaloids has been developed starting from commercially available 3-methylanisole. Key features of this approach are an intramolecular Michael addition/allylation sequence and a ring-closing metathesis step.
