[reaction: see text] Oxidative cyclizations of 2-(4-hydroxybutyl)furan derivatives provide spirobutenolide acetals directly; on the basis of this methodology, we describe an asymmetric synthesis of a tricyclic spirobutenolide precursor to the C(7-18) fragment common to lituarines A-C.
[反应：见正文] 2-(4-羟丁基)呋喃衍生物的氧化环化反应可直接生成螺丁烯内酯缩醛；基于此方法，我们描述了一种对三环螺丁烯内酯前体的不对称合成，该前体是海石花碱A-C共有的C(7-18)片段。
