  分子内碳甲酸酯化反应制备氮杂双环

  摘要：

  锡-锂交换和分子内碳锂化（阴离子环化）已被用于构建氮杂双环[2.2.1]庚烷环系统的三个氮-位置异构体。7-氮杂双环[2.2.1]庚烷环系通过手性有机锂中间体从2,5-二取代的吡咯烷的任一非对映异构体获得。2-氮杂双环[2.2.1]庚烷环系统是通过串联环化与单环化产物一起以低产率立体选择性地形成的。尽管锡（以及锂）原子和烯丙基单元的反式排列，也可以使用另一种方法从2-三丁基锡烷基-4-烯丙基吡咯烷中获得更好的2-氮杂环系统产率。1-氮杂双环[2.2.1]庚烷环系统距离4-哌啶酮仅三步。

  The ESPD charge of at least one atom in an atomic group forming a functional group included in an activating catalyst is in a range between -0.65 and -1.05 (electrons). Alternately, an activating catalyst includes a cyclic quaternary ammonium group as the functional group and the ESPD charge of a nitrogen atom forming the ammonium group is in a range between +0.4 and +1.3 (electrons). Consequently, the catalyst can efficiently activate an active hydrogen included in a compound using the atom showing the ESPD charge in the above-specified range as an active site. In other words, the catalyst can be suitably used as an activating catalyst for various reactions involving the activation of the active hydrogen. Also, by using the activating catalyst, a reaction with excellent selectivity can be conducted.
