关于制备 une serie de dihydroxy-2,3 cyclohexones et cyclopentanones di-ou trisubstituees, a partir des cyclenones相应的反应 avec le N-methyl S-methyl S-phenyl sulfoximide
Synthetic studies towards the construction of the cyclopenta[a]indene fragment of the heptacyclic marine metabolite sporolide are reported based on a hypothetical biosynthesis. The key step of this biogenetic proposal includes a Bergman cyclization of an enediyne precursor. The enediyne target of this synthetic study was prepared by Sonogashira cross-coupling of two fragments, of which the cyclopentane
基于假想的生物合成,报道了关于七环海洋代谢物子孢子化物的环戊[ a ]茚片段的构建的合成研究。该生物遗传学提议的关键步骤包括烯二炔前体的Bergman环化。该合成研究的烯二炔目标物是通过两个片段的Sonogashira交叉偶联制备的,其中环戊烷片段是由环戊烯酮,Morita-Baylis-Hillman反应和对映选择性Sharpless二羟基化制备的。 交叉偶联-天然产物-氧化-立体选择性合成-全合成
