  A Short Total Synthesis of rac -Peniolactol

  摘要：

  A short facile synthesis of the fungal metabolite (+/-)-3,4-dihydro-3,6,8-trihydroxy-3-pentadecylisocoumarin (peniolactol) has been achieved. Condensation of hexadecanoyl chloride with 3,5-dimethoxyhomophthalic acid afforded 6,8-dimethoxy-3-pentadecylisocoumarin, which on sequential saponification and demethylation furnished rac-peniolactol in 31% overall yield. The ring-chain tautomerism was studied in solution by H-1 NMR and the mass fragmentation pattern. 3-Pentadecylisocoumarin was also synthesized and saponified to the corresponding keto acid as a model compound for comparative studies.
