Di-O-methylhydroxythujaplicatin Methyl Ether, Pluviatolideおよび2-(3", 4"-Dimethoxybenzyl)-3-(3', 4'-methylenedioxybenzyl)butyrolactoneの絶対配置の化学的証明

抄録

The chemical assignments were given to the absolute configurations of di-O-methylhydroxythujaplication methyl ether (I) (2S, 3S), pluviatolide (VI) (2R, 3R), and 2-(3", 4"-dimethoxybenzyl)-3-(3', 4'-methylenedioxybenzyl) butyrolactone (VII) (2R, 3R) by their conversion to known compounds, whose absolute configurations have already been established. The present results agreed with the assignments proposed previously on the basis of optical rotatory dispersion and circular dichroism of these compounds.
