Résumé

Dihydro-β-agarofuran sesquiterpenoids possess chemical diversity and biodiversity. A dihydro-β-agarofuran sesquiterpenoid with only hydroxyl groups has been prepared by basic hydrolysis of crude extract of Euonymus bungeanus with 0.4% yield. Twelve derivatives were available in esterification, oxidation, decarboxylation, etc. Extensive ~1H-NMR,~(13)C-NMR, MS spectroscopic analyses and single-crystal X-ray diffraction analysis with Cu Kα radiation indicated that eleven derivatives were new compounds. The results will provide reference for chemistry study on natural product derivatives of dihydro-β-agarofuran sesquiterpenoids.
