Total Synthesis of (±)‐Aspidophylline A

A total synthesis of aspidophylline A, a pentacyclic akuammiline‐type monoterpene indole alkaloid, is described. The synthesis features: 1) rapid access to a fully functionalized dihydrocarbazole through the desymmetrization of readily available 2‐allyl‐2‐(o‐nitrophenyl)cyclohexane‐1,3‐dione; 2) an intramolecular azidoalkoxylation of an enecarbamate to install both the furoindoline ring and the azido functionality; and 3) an intramolecular Michael addition for the construction of the 2‐azabicyclo3.3.1]nonane ring system.
