Tandem radical addition-cyclization of oxime ethers anchored to polymer support was studied. The reaction of oxime ethers with stannyl radical proceeded effectively by the use of triethylborane as a radical initiator. The alkyl radical addition-cyclization reactions of oxime ether connected with alpha,beta-unsaturated carbonyl group proceeded under iodine atom-transfer reaction conditions to give the
研究了固定在聚合物载体上的肟醚的串联自由基加成环化反应。肟醚与苯乙烯基自由基的反应通过使用三乙基硼烷作为自由基引发剂有效地进行。与碘,β-不饱和羰基连接的肟醚的烷基加成环化反应在碘原子转移反应条件下进行,通过两个碳-碳键形成过程得到官能化的氮杂环。
