The enantioselective total synthesis of marine sesquiterpenoid sinularianin B, isolated from the Formosan soft coral Sinularia sp., has been accomplished in 16 steps based on a highly concise synthetic strategy. The synthesis features two highly stereoselective sulfone-mediated reactions, including a key tandem intemiolecular-intramolecular alkylation developed in our laboratory, and a palladium-catalyzed desulfonylation of an allyl sulfone through pi-allyl palladium complex formation.
