标题:Synthesis Of (−)-Matairesinol,(−)-Enterolactone,And (−)-Enterodiol From The Natural Lignan Hydroxymatairesinol
摘要:[graphics]We Describe Here A Four-Step Semisynthetic Method For The Preparation Of Enantiomerically Pure (-)-Enterolactone Starting From The Readily Available Lignan Hydroxymatairesinol From Norway Spruce (Picea Abies). Hydroxymatairesinol Was First Hydrogenated To Matairesinol. Matairesinol Was Esterified To Afford The Matairesinyl 4,4'-Bistriflate,Which Was Deoxygenated By Palladium-Catalyzed Reduction To 3,3'-Dimethylenterolactone. Demethylation Of 3,3'-Dimethylenterolactone And Reduction With Lialh4 Yielded (-)-Enterolactone And (-)-Enterodiol,Respectively.
