The first totalsynthesis of the Hawaiian mollusk metabolite pulo'upone (2) has been achieved, wherein a novel retro hetero Diels-Alder/intramolecular Diels-Alder tandem process established the trans-fused hydrindene nucleus.
A mmolar scale synthetic route to (+/-)-pulo'upone, in 9 steps, 3.8% overall yield, and under non-epimerizing conditions, is reported. A complete assignment of the compound's H-1 and C-13 NMR shifts is presented.
