A concise enantioselective total synthesis of three sesquiterpenoid alkaloids—(−)-dendrobine, (−)-mubironine B, and (−)-dendroxine—is presented, which highlights the state-of-art catalytic methods, including enantioselective Diels–Alder cycloaddition, iron-catalyzed aerobic lactonization, copper-catalyzed cycloisomerization, and free-radical-initiated hydroazidation.
