Abstract
An anionic oxy-Cope/transannular Michael addition cascade converts a spirocyclic architecture-readily available by Diels-Alder cycloaddition-into the hydrophenalene carbon skeleton of the pseudopterosin aglycones. Oxidation of the resulting cyclohexenone ring to the phenol that is characteristic of the targets completes a short formal synthesis.
摘要
阴离子氧-Cope/跨环迈克尔加成级联反应将螺环结构（通过 Diels-Alder 环加成反应很容易获得）转化为假珊瑚素苷元的氢化菲烷碳骨架。所得环己烯酮环氧化为目标物特征性的酚完成了简短的形式合成。
