  Reinforcing effect of bi- and tri-cyclopolyprenols on ‘primitive’ membranes made of polyprenyl phosphates

  摘要：

  Cholesterol plays the role of membrane reinforcer in eukaryotes, whereas hopanoids play the same role in bacteria. Which components could have reinforced 'primitive' membranes? We describe here an efficient biomimetic synthesis of bi- and tri-cyclopolyprenols and demonstrate that these compounds reinforce the membranes of polyprenyl phosphate, which we speculated as 'primitive' membranes.

• Synthesis of (±)-Isopiperitenol by Fluoride Ion Mediated Cyclization of Allylsilane Moiety Incorporated in Terpene Aldehydes
  作者：Hideshi Nakamura、Toyohisa Oya、Akio Murai

  日期：1992.3

  Fluoride ion mediated cyclization of aldehydes (1 and 2) having regioisomeric allylsilane functionalities give a mixture of cis- and trans-isopiperitenol (3). The aldehydes (1) reacted faster and showed better stereoselectivity than the regioisomeric aldehydes (2) regardless of geometry of the double bond at an unsaturated aldehyde.

  在氟离子介导下，具有烯丙基硅烷官能团异构体的醛（1 和 2）发生环化反应，生成顺式和反式异哌啶醇（3）的混合物。无论不饱和醛双键的几何形状如何，醛（1）的反应速度和立体选择性均优于醛（2）的 Regioisomeric。
• Synthesis of Allylsilanes by Reductive Lithiation of Thioethers

  日期：2004.10.1

  Although much work in reductive lithiation has been done, the utilization of allylthioethers bearing various substituents to prepare allylsilanes has not been explored. The main reason clearly stems from the anticipated lack of regioselectivity. We describe herein the first study on the regioselectivity of the reductive silylation involving dissymmetric allylthioethers. We surveyed a broad spectrum of parameters and showed that this process displays a great dependence of the reaction conditions. We also discovered that an electron transporter, DBB or naphthalene, can cleave THF at room temperature by sonication, to generate a strong base, 4-lithiobutoxide. This feature was successfully exploited to the straightforward synthesis of bis-silanes in one pot. Examples are provided for maximizing both the chemical yield and the regioselectivity of the reductive silylation through the tuning of the reaction conditions. By changing these conditions, several allylsilanes can be selectively synthesized from one thioether.
