This review summarizes the new carbon-carbon bond construction methods based on the radical reaction of imine derivatives. The intermolecular carbon radical addition to oxime ethers proceeded smoothly in the presence of BF3.OEt2. A high degree of stereocontrol in the reaction of oxime ethers was achieved to give amino acid derivatives with excellent diastereoselectivities. The radical reaction of imine derivatives in water has also been investigated. The radical cyclization of oxime ethers proceeded effectively to provide the functionalized heterocycles via a carbon-carbon bond-forming process. These reactions were extended to the solid-phase radical reactions using triethylborane or diethylzinc as a radical initiator.
本综述总结了基于亚胺衍生物自由基反应的新型碳-碳键构建方法。在三氟化硼乙醚存在下,肟醚的分子间碳自由基加成反应顺利进行。肟醚反应实现了高度的立体控制,以优异的非对映选择性得到氨基酸衍生物。还研究了亚胺衍生物在水中的自由基反应。肟醚的自由基环化反应通过碳-碳键形成过程有效地进行,提供了功能化杂环。这些反应扩展到使用三乙基硼或二乙基锌作为自由基引发剂的固相自由基反应。
