Eighteen new β-dihydroagarofuran derivatives were designed and synthesized using 1β,2β,4α,6α,8β,9α,12-heptahydroxy-β-dihydroagarofuran as starting material, and the structures of all target compounds were confirmed, mainly from 1H NMR and 13C NMR spectral data. Insecticidal activities of these β-dihydroagarofuran derivatives were assayed against sixth-instar larvae of Mythimna separata moths. Results...
