We have shown that connection of C-2 of an allylsilane to a tethered aziridine ring yields exocyclic γ-amino olefins and desilylated azabicyclo[x.2.1]-systems upon cyclization with BF3·OEt2. Furthermore, manipulation of a specific exocyclic γ-amino olefin provided access to an azabicyclo[3.3.1]nonane. This methodology should be useful for the preparation of natural products and pharmacologically active
我们已经表明,在用BF 3 ·OEt 2环化后,烯丙基硅烷的C -2与束缚的氮丙啶环连接会生成环外γ-氨基烯烃和脱甲硅氮杂双环[ x .2.1]-系统。此外,对特定的环外γ-氨基烯烃的操作提供了访问氮杂双环[3.3.1]壬烷的途径。该方法学对于制备包含这些双环杂环系统的天然产物和药理活性剂应该是有用的。
