  一锅串联路线合成吲哚并咪唑和喹啉并咪唑：在生物碱和生物活性化合物的合成中的应用

  摘要：

  融合的吲哚并立定和喹喔啉是多种天然产物和重要药理化合物的重要骨架。公开了一种从酰胺到稠合的吲哚并咪唑和喹喔啉的一锅串联路线。该方法在温和条件下进行，显示出对官能团的良好耐受性。它也容易按比例放大至克级，并且可以平滑地应用于生物碱的全合成，例如（±）-crispine A，（±）-xylopinine，（±）-desbromoarborescidine A，（±）-harmicine和其他生物活性物质。

  The use of immobilized crown ethers as in-situ N-protecting groups in organic synthesis and their application under continuous flow

  摘要：

  In addition to their high affinity for inorganic cations, crown ethers have been shown to efficiently sequester ammonium ions, forming a stable adduct via hydrogen bonding. Using this principle, several authors have reported the use of crown ethers as protecting groups for amines however to date, their widespread use has been somewhat precluded by the difficulties associated with removal of the crown ether from the resulting reaction mixture. In order to address this problem, we report the preparation of an immobilized 18-crown-6 ether derivative and its incorporation into a flow reactor, demonstrating the ability to use and recycle the reagent for the chemoselective O-acylation and alkylation of bifunctional compounds such as 4-(2-aminoethyl)phenol and 4-nitrophenol.

  A facile and efficient N-tert-Boc protection of amines is described by the reaction of various primary, secondary, benzylic and aryl amines with di-tert-butyl dicarbonate in the ionic liquid [TPA][Pro] at room temperature. All the N-tert-butylcarbamates are afforded in excellent yields. A catalyst-free method was developed and the ionic liquid [TPA][Pro] can be recovered and reused for several times without loss of its activity.
