The enantiocontrolled total synthesis of (+)-helianane, a marine-derived heterocyclic sesquiterpene, has been accomplished with an efficient chirality transfer during the Me 3 Al-mediated aromatic Claisenrearrangement and a ring-closing metathesis as the key steps. The absolute structure of the natural product has been firmly established by total synthesis.
(+)-helianane 的对映控制全合成是一种海洋衍生的杂环倍半萜烯,在 Me 3 Al 介导的芳香 Claisen 重排和闭环复分解作为关键步骤期间通过有效的手性转移完成。天然产物的绝对结构已通过全合成牢固确立。
