From ring to ring: The first total synthesis of (+)‐daphmanidin E features rapid access to an enantiomerically pure bicyclo[2.2.2]octadione and elaboration around its periphery through the implementation of two Claisen rearrangements, the use of a copper/peptide complex for reagent‐controlled stereoselective conjugateaddition, a diastereoselective hydroboration, and a cobalt‐catalyzed alkyl‐Heck cyclization
