- 論文の詳細を見る
The structure (III) including absolute configuration was proposed for pseudoanisatin, C_<15>H_<22>O_6, a sesquiterpene lactone component obtained from the fruits of Illicium anisatum Linn. (Magnoliaceae) on the basis of the following evidences. a) Pseudoanisatin gave a triacetate (IV) and a ketone (V) on periodate oxidation. V was reduced to XI by sodium borohydride reduction. b) A translactonization product (VII) was obtaind by treating with sodium methoxide in methanol solution. VII gave IX on Jones oxidation. X was obtained from VII with thionyl chloride. c) The IR, MS and NMR (including NMDR and NOE) spectra of these compounds were all compatible with these structures. d) The molecular rotation difference between V and its 3-monobenzoate was estimated as +85°, showing S-configuration at C-3.
