  Selective Monocyclization of Epoxy Terpenoids Promoted by Zeolite NaY. A Short Biomimetic Synthesis of Elegansidiol and Farnesiferols B−D

  摘要：

  Epoxy terpenes cyclize readily, by confinement within zeolite NaY, to form exomethylenic cyclohexanols as the major products. The selective monocyclization of 10,11-epoxyfarnesyl acetate within NaY provides a short and efficient biomimetic route to (+/-)-elengasidiol and (+/-)-farnesiferols B-D.

  the brown algae Cystophora monoliformis. The optical rotation of achilleol A derived from the cyclization of (S)-2,3-epoxysqualene matches with that of the natural product, thus the absolute configuration of achilleol A was established as 1S,3R. From the mechanistic point of view, the NaY-promoted cyclization of 9,10-epoxygeranylacetone, selectively deuterium labelled at the C-10 methyl group, is >97%

  通过限制在NaY沸石中，各种环氧多烯萜容易环化，主要形成单环化产物。不管环氧萜烯的侧链如何，单环化途径都非常占优势，而单环产物具有区域选择性地具有外亚甲基双键。在乙酸法呢烯基乙酸酯，环氧法呢烯基丙酮或2,3-环氧角鲨烯的情况下，选择性单环化为合成多种天然产物（例如榄香二醇，法呢香酚B–D，阿奇儿醇A，山茶酚C和四种法呢基丙酮）提供了直接途径。褐藻中提取的代谢产物。由（S的环化引起的Achilleol A的旋光。基）-2,3-环氧角鲨烯与天然产物的匹配，从而achilleol A的绝对构型确定为1小号，3 - [R 。从机理的角度来看，NaY促进的9,10-环氧香叶基丙酮（在氘代C-10甲基上进行选择性氘标记）的环化相对于宝石-二甲基基团的局部立体选择性> 97％。这一结果与协调机制相吻合。最后，我们首次通过标记实验证明，环氧多烯萜烯在酸催化下向2,3,4-三甲基环己酮的仿生转化是高度立体选

  The first total synthesis of (-)-achilleol B was achieved using a convergent approach with a longest linear sequence of 14 steps. Three key steps were employed, including an enantioselective Robinson annelation for the construction of the bicyclic moiety. The monocyclic synthon was prepared through a Ti(III)-mediated cylization of a chiral monoepoxide obtained via asymmetric dihydroxylation of geranylacetone

  （-）-achilleol B的第一个全合成使用收敛方法进行，最长线性序列为14个步骤。使用了三个关键步骤，包括用于构建双环部分的对映选择性Robinson脱嵌。单环合成子是通过手性单环氧化物的Ti（III）介导的环化反应而制备的，手性单环氧化物是通过香叶基丙酮的不对称二羟基化反应获得的。这些亚基的不对称制备也使我们能够实现线虫二醇，阿奇烯醇A和法呢酚B的对映选择性合成。
