of polycyclic alkaloids. The first totalsynthesis now proves that the structure of this compound had originally been misassigned. The route to (−)-1 is based on a double Michael addition for the formation of the bridged diazadecalin core and a palladium-catalyzed decarboxylative allylation to install the quaternary bridgehead center. Ring-closingalkynemetathesis allowed a 13-membered cycloalkyne
