In this contribution, two methods are presented for the removal of benzyl-type protecting groups attached to the nitrogen atom of 2-azabicyclo[3.1.0]hexane and 2-azabicyclo[4.1.0]heptane systems. The first, based on the Polonovski reaction, is suitable for [3.1.0] systems. The second relies on an elimination process, starting from derivatives of O-methyl phenylglycinol, and is more general in terms
在这一贡献中,提出了两种方法来除去连接在2-氮杂双环[3.1.0]己烷和2-氮杂双环[4.1.0]庚烷系统的氮原子上的苄基型保护基。第一种基于Polonovski反应,适用于[3.1.0]系统。第二种依赖于消除过程,该过程从O-甲基苯基甘氨醇的衍生物开始,并且在可耐受的底物方面更为普遍。因此可以得到包括对映体纯的分子的仲双环环丙胺。这些化合物然后准备进一步功能化。
