Abstract The AC bicyclic skeleton of daphniyunnine B with the required 3 stereocenters (C4, C5 and C8) was accomplished in a concise route which featured two Claisen-type rearrangement reactions to construct the required vicinal all carbon quaternary stereocenters (C5 and C8) and an intramolecular iodo-cyclization reaction to assemble the cis-confused bicyclic lactam.
