    摘要:
    开发了一种在硫醚和1,3-二烯之间形成正式的[4 + 1]环化策略,以提供功能化的环戊烷类化合物。该过程包括立体选择性环丙烷化反应,然后原位进行立体特异性MgI 2催化的乙烯基环丙烷-环戊烯重排。手性硫的使用为环戊烷提供了优异的对映体控制能力。结合实验和计算机理的研究表明,重排的立体特异性可以由涉及碘化物的双重S N 2反应机理解释。

  • Formal Asymmetric (4+1) Annulation Reaction between Sulfur Ylides and 1,3-Dienes
    作者:Olivier Rousseau、Thierry Delaunay、Geoffroy Dequirez、Tran Trieu-Van、Koen Robeyns、Raphaël Robiette
    DOI:10.1002/chem.201502579
    日期:2015.9.7
    A highly enantioselective synthesis of functionalized cyclopentanoids by a formal asymmetric (4+1) annulation strategy was developed. The methodology consists of a stereoselective cyclopropanation reaction between chiral sulfur ylides and 1,3‐dienes followed by a, in situ, stereospecific MgI2‐catalyzed rearrangement of vinylcyclopropanes. This method is distinguished by a remarkable compatibility with

    公开(公告)日:1981-04-08
    A quick-setting adhesive composition comprises a 2-cyanoacrylate and at least one 1,1-disubstituted diene, the amount of said diene being greater than 50% of the total weight of the two components. This composition can be used in place of conventional 2-cyanoacrylate adhesives but has improved impact resistance, peel resistance, heat resistance and water resistance.
