  Epoxidation of olefins by β-bromoalkoxydimethylsulfonium ylides

  摘要：

  Olefins can be converted to their respective epoxides in a one-pot procedure by dissolving the olefin in anhydrous DMSO, adding NBS to the reaction mixture to generate a beta-bromoalkoxydimethylsulfonium ylide, and then adding DBU to the reaction mixture. A large variety of alkenes were successfully epoxidized with yields largely dependent on the structure of the alkene. Most importantly, the facial selectivity of this one-pot process is the opposite of that observed when using traditional epoxidizing reagents. Electron-poor alkenes are not epoxidized under these conditions. (C) 2010 Published by Elsevier Ltd.

  The invention provides an industrially advantageous method for the production of hydroxyalkylated polyrotaxanes. The method of producing hydroxyalkylated polyrotaxane includes reacting a polyrotaxane with a cyclic ether represented by Formula (1) in the presence of water and an organic base, wherein the polyrotaxane includes hydroxyl group-containing cyclic molecules, a linear molecule threaded through the cyclic molecules to form a clathrate, and blocking groups at both ends of the linear molecule to prevent the separation of the cyclic molecules from the linear molecule.

  本发明提供了一种具有工业优势的羟基烷基化聚罗他赛生产方法。生产羟烷基化聚罗他赛烷的方法包括在水和有机碱存在下，将聚罗他赛烷与由式（1）表示的环醚反应，其中聚罗他赛烷包括含羟基的环状分子、穿过环状分子以形成凝块的线性分子，以及位于线性分子两端以防止环状分子与线性分子分离的封端基团。
