The regioselective synthesis and Diels-Alder cycloaddition of 3-(3,4-dimethoxyphenyl)-5-bromo-2-pyrone provided a new efficient synthetic route to joubertinamine (9.6% total yield over 10 steps).
Opening of aryl-substituted epoxides to form quaternary stereogenic centers: Synthesis of (-)-mesembrine

Cycloalkanones are easily converted into aryl-substituted cyclic alkenes by the addition of an aryl Grignard reagent followed by dehydration. These alkenes are good substrates for asymmetric epoxidation. We have found that the addition of allylic and benzylic Grignard reagents can occur preferentially at the benzylic position of the derived epoxides to give the quaternary stereogenic center. This approach led to a short synthesis of the nanomolar serotonin re-uptake inhibitor (-)-mesembrine.

A synthesis of seco-mesembrane alkaloids, (+/-)-joubertiamine (4), (+/-)-joubertinamine (5), and (+/-)-epijoubertinamine (6), was accomplished starting with 2-allyl-2-aryl-5,5-ethylenedioxycyclohexanones (10 and 3), which are readily available by allylati
SCELETIUM (AIZOACEAE) ALKALOIDS: TOTAL SYNTHESIS OF RACEMIC MESEMBRANONE, JOUBERTINAMINE AND EPIJOUBERTINAMINE
Sanchez, Ignacio H.,Soria, Jose de Jesus,Larraza, Maria Isabel,Flores, Humberto J.
, p. 551 - 554 (2007/10/02)
The total synthesis of the Sceletium alkaloids mesembranone, joubertinamine and epijoubertinamine via the intramolecular cyclization of an enone to a benzensulfonamide grouping under the conditions of a dissolving metal reduction is described.
