  Development of a Scalable Synthesis of a Common Eastern Tricyclic Lactone for Construction of the Nodulisporic Acids

  摘要：

  A scalable, second-generation synthesis of the densely functionalized eastern tricyclic lactone (+)-6, a common intermediate, for construction of the nodulisporic acids has been achieved. Modifications to the first-generation route now permit access to (+)-6 in 17 steps with an overall 16.5% yield. Key carbon-carbon bond constructions include a Kirk-Petrow (phenylthio)methylation, a Sc(OTf)(3)-catalyzed hydroxymethylation, a Stille carbonylation, and a Koga three-component, conjugate addition-alkylation sequence.

  DOI：10.1021/ol016888t

  日期：2001.11.1

  In this, the second of two Letters, we describe an effective assembly of (+)-4, an eastern hemisphere subtarget comprising the FGH rings of (+)-nodulisporic acid A (1) (17 steps, 9% overall yield). Central to the synthesis is a Koga three-component conjugate addition-alkylation sequence which secures the trans orientation of the vicinal quaternary methyl groups. [reaction: see text]

  在本文中，这是两个字母的第二个字母，我们描述了（+）-4的有效组装，这是一个包含（+）-去甲孢子酸A（1）的FGH环的东半球子目标（17个步骤，总产率为9％）。合成的中心是Koga三组分共轭加成烷基化序列，可确保邻位季甲基的反式定位。[反应：看文字]
