We report a concise, stereocontrolled synthesis of the neuro- toxic sesquiterpenoid, (–)-picrotoxinin (1, PXN). The brevity of the route owes to regio- and stereoselective formation of the [4.3.0] bicyclic core by incorporation of a symmetrizing geminal dimethyl group at C5. Dimethylation then enables selective C–O bond formation in multiple intermediates. A series of strong bond (C–C and C–H) cleavages convert the C5 gem-dimethyl group to the C15 lactone of PXN.
