chlorination of polyprenoids and titanocene-mediated radical cyclization of epoxypolyprenes. We have applied this synthetic route to the first synthesis of the diterpene, (13E)-ent-labda-8(17),13-diene-3β,15,18-triol. A stereoselective approach to this synthesis is also described. diterpene - radical cyclizations - oxiranes - stereoselective synthesis - titanocene
描述了一种简单的A-环-γ-双加氧萜类化合物的方法,该方法涉及两个关键步骤,即硒催化的聚戊二烯选择性烯丙基氯化和钛茂介导的环氧聚戊二烯自由基环化。我们应用此合成路线双萜的第一合成,(13 ë) - ENT -labda-8(17),13-二烯3β,15,18三醇。还描述了用于这种合成的立体选择方法。 二萜-自由基环化-oxiranes-立体选择性合成-钛茂
