of allylic/benzylic alcohols or their methyl ethers followed by the click reaction are reported. Two methods involving sequential reactions were developed for synthesizing substituted 1,2,3-triazoles starting from allylic/benzylic alcohols. The first method involves magnetically separable nano Fe3O4-catalyzed direct azidation of various allylic/benzylic alcohols with TMSN3 as the first step followed
报道了对烯丙基/苄基醇或其甲基醚的一锅直接叠氮化并随后进行点击反应的研究。开发了两种涉及顺序反应的方法,用于从烯丙基/苄基醇开始合成取代的1,2,3-三唑。第一种方法涉及第一步,以TMSN 3进行磁性可分离的纳米Fe 3 O 4催化的各种烯丙基/苄基醇的直接叠氮化,然后第二步进行叠氮化物与炔烃的Cu催化点击反应。第二种方法涉及Cu(OTf)2催化烯丙基/苄醇及其甲基醚与TMSN 3的直接叠氮化。第一步,然后进行叠氮化物与炔烃的点击反应,作为第二步。在该方法中,Cu(OTf)2用作酒精叠氮化和点击反应步骤的单一催化剂。通过合成嵌入1,2,3-三唑和1,3-二炔单元的新型聚醚系统和大分子化合物,已揭示了该方案的实用性。
