  摘要：

  摘要 通过 Cu(I) 介导的 1,3-偶极环加成反应高效合成了几种 1,2,3-三唑连接的糖缀合物，具有高区域特异性和产率（≥ 85%），为合成受保护和未受保护的新糖缀合物。在糖基部分和其他化合物之间引入间隔基可减少空间位阻，提高产量，并扩大糖缀合物的种类以满足生物事件的各种需要。所有合成的糖缀合物的结构均通过红外 (IR)、1H NMR、13C NMR、元素分析 (EA) 或 MS 明确证实。

• Visible light induced 3-position-selective addition of arylpropiolic acids with ethers <i>via</i> C(sp³)–H functionalization
  作者：Zi-juan Wan、Xiao-feng Yuan、Jun Luo

  DOI：10.1039/d0ob00480d

  日期：——

  Although the 2-position-selective decarboxylative coupling or addition of arylpropiolic acids with cyclic ethers has been intensively investigated, selective functionalization of arylpropiolic acids at the 3-position is still a big challenge.

  尽管对芳基丙炔酸与环氧化物进行2位选择性脱羧偶联或加成的研究已经得到深入探讨，但对芳基丙炔酸在3位的选择性官能化仍然是一个重大挑战。
