  Novel Regio- and Stereoselective Cascade 6-endo-trig Cyclisations from Polyene Acyl Radical Intermediates Leading to Steroid-Like Pentacycles and Heptacycles

  摘要：

  In a quite remarkable regio- and stereoselective manner, each of the (all-E)-polyene selenoates 5a-c is shown to undergo cascade radical-mediated polycyclisations via consecutive 6-endo-trig reactions, leading to the corresponding all-trans, anti, tri-, penta- and heptacycles, i.e., 20, 23, and 25, in good yields. The configurations of these 'steroid-like' polycycles followed from detailed examination and correlation of chemical shift data in their C-13-NMR spectra.

• A Strategy for Position-Selective Epoxidation of Polyprenols
  作者：Vijay Gnanadesikan、E. J. Corey

  DOI：10.1021/ja801899v

  日期：2008.6.1

  developed for the efficient site-selective epoxidation of poylolefinic isoprenoid alcohols, based on the use of an internal control element for intramolecular reaction. The approach is illustrated by application to a series of polyisoprenoid alcohols (polyprenols) at substrate concentration of 0.5 mM. With polyprenol substrates having the hydroxyl function at one terminus, the internal epoxidation can be directed

  基于使用内部控制元件进行分子内反应，已开发出一种有效的策略，用于聚烯烃类异戊二烯醇的有效位点选择性环氧化。该方法通过应用于一系列底物浓度为 0.5 mM 的聚异戊二烯醇（聚异戊二烯醇）来说明。对于在一个末端具有羟基官能团的聚异戊二烯醇底物，内部环氧化作用可针对聚异戊二烯醇的双键，该双键距末端羟基异戊二烯亚单元四或五处。
• A Biomimetic Synthesis of Sacculatane Diterpenoids

  日期：2008.2

  The biomimetic synthesis of sacculatane-type epimeric compounds 14a and 14b is reported. The key synthetic step is the low-temperature superacidic cyclization of (all-E)-ω-acetoxygeranylgeraniol 12 obtained in nine steps from geranyllinalool (13). The 19-acetoxysacculata-7,17-dien-11-ol (14a) could be an important and convenient starting compound for the synthesis of other sacculatane diterpenoids.

  已报道了acc草型的差向异构化合物14a和14b的仿生合成。关键的合成步骤是在九个步骤中从香叶薄荷醇（13）获得的（全-E）-ω-乙酰氧基香叶基香叶醇12的低温超酸性环化。19-乙酰氧基acculata-7,17-dien-11-ol（14a）可能是合成其他sacculatane二萜类化合物的重要且方便的起始化合物。
