The nucleophilic opening of functionalized azetidinium ions by C-nucleophiles was screened. Malonate and cyanide anions reacted in a highly regio- and chemoselective way leading to functionalized pure amines. The success of this reaction was found to be highly dependent on the basicity of the involved nucleophiles and the competitive reactions induced by too basic reagents were identified.
筛选了C-亲核试剂对官能化氮杂环丁鎓离子的亲核开放。丙二酸和氰化物阴离子以高度区域和化学选择性的方式反应,生成功能化的纯胺。发现该反应的成功高度依赖于所涉及亲核试剂的碱性,并且鉴定出由碱性太强的试剂诱导的竞争性反应。
