(+)-mesembrine (1) and (+)-mesembranol (2) has been achieved from the monoterpene (S)-(−)-perillyl alcohol. Key transformations include a diastereo- and regioselective Pd-mediated intramolecularHeckreaction, and a double reduction of the resultant cyclicsulfonamide, to afford the cis-3a-aryloctahydroindole skeleton.
