Stereoselective synthesis of zooxanthellactone

The marine polyunsaturated natural product zooxanthellactone was synthesized in six steps and in 11% overall yield from eicosapentaenoic acid. The key synthetic steps were a Sonogashira cross-coupling reaction and a stereoselective semi-reduction. These efforts, together with NMR and optical rotation data, confirmed the reported structure of zooxanthellactone.

Synthesis of Chiral Hydroxylated Quinolizidines via Vinylogous Bischler-Napieralski Nitrilium Ion Cyclizations

Treatment of the amido esters 9 and 17 with PPSE (polyphosphoric acid trimethylsilyl ester) followed by NaBH4 in ethanol gave the quinolizidinones 11-14 and 19 via a vinylogous Bischler-Napieralski nitrilium ion cyclization-reductive lactamization two-step process.Subsequent ozonolysis and reduction afforded chiral hydroxylated quinolizidines in moderate to good yield.In contrast to five-membered-ring formation, six-membered-ring formation via nitrilium-ion cyclization requires a p-methoxy-substituted styryl terminator.The effect para-substituted styryl terminators have on the energy of activation and DeltaH for the cyclization process has been calculated by semiempirical and ab initio methods.

Radical cyclizations of acylsilanes in the synthesis of (+)-swainsonine and formal synthesis of (-)-epiquinamide

Radical cyclization of acylsilane is an useful synthetic methodology. To demonstrate the versatility of this method using the cyclization as a key step, polyhydroxylated indolizidine (+)-swainsonine was synthesized through two different bond connection approaches to construct the bicyclic skeleton. In the first approach, we used 2,3-isopropylidene-d-ribono-1,4-lactone (20) as a chiral building block to form the indolizidine skeleton through a 1,6-cyclization. In the second approach, (S)-(+)-5-oxo-2-tetrahydrofurancarboxylic acid (23) was used to construct the same ring system through a 1,5-cyclization. Starting from acid 23, we also synthesized exo-1-hydroxyquinolizidin-4-one (56), which was a synthetic intermediate in the synthesis of polyhydroxylated quinolizidine (-)-epiquinamide. 2011 Elsevier Ltd.
