  • Continuous Flow Synthesis of Terminal Epoxides from Ketones Using in Situ Generated Bromomethyl Lithium
    作者:Timo von Keutz、David Cantillo、C. Oliver Kappe
    DOI:10.1021/acs.orglett.9b04072
    日期:2019.12.20
    preparation of epoxides from ketones has been developed. The method is based on the carefully controlled generation of (bromomethyl)lithium (LiCH2Br) from inexpensive CH2Br2 and MeLi in a continuous flow reactor. The reaction has shown excellent selectivity for a variety of substrates, including α-chloroketones, which typically fail under classic Corey-Chaykovsky conditions. This advantage has been used to develop
    已经开发了从酮直接制备环氧化物的可扩展程序。该方法基于在连续流反应器中从廉价的CH2Br2和MeLi中精心控制的(溴甲基)锂(LiCH2Br)生成。该反应对多种底物(包括α-氯酮)表现出出色的选择性,这些底物通常在经典的Corey-Chaykovsky条件下失效。这一优势已被用于开发一种新的药物氟康唑的途径。
  • A novel synthesis of γ-lactones by tandem epoxide opening-cyclization reaction mediated by samarium(II) diiodide

    Various epoxy esters readily reacted with SmI2 (2 equiv) in the presence of ethyl bromoacetate (1 equiv) and HMPA (6 equiv) under mild conditions (THF, −78 °C, 2 h, Ar) providing the corresponding γ-lactones via tandem epoxide opening-cyclization reaction in good to excellent yields.
    在温和的条件下(THF,-78°C,2 h,Ar),在溴乙酸乙酯(1当量)和HMPA(6当量)存在下,各种环氧酯容易与SmI 2(2当量)反应,提供相应的γ-内酯通过串联环氧化物开环反应,收率良好。
  • Preparation of 2-halo-5-methylpyridines from 4-methyl-4-pentene
    申请人:ICI Americas Inc.
    公开号:US04709063A1
    公开(公告)日:1987-11-24
    A method of preparing certain 2-halo-5-methylpyridines, useful as herbicide intermediates, is presented starting from acyclic pentenes. The pentene is difunctionalized, e.g., by making the epoxide, and is then reacted with a nitrogen source to close the ring. The nitrogen-containing 6-membered heterocycle may then be aromatized readily to produce the 2-halo-5-methylpyridine desired. Also part of the invention are novel acyclic and cyclic intermediates used in the process.
