4,6-Bis(bromomethyl)-N1,N3-bis(tert-butoxycarbonyl)benzene-1,3-diamine is introduced as a general starting compound for the preparation of bis-Tröger's base (bisTB) derivatives in excellent yield in just two steps. The synthetic sequence includes treatment of the above-mentioned protected diamine with an arylamine followed by in situ deprotection and the final bisTB-forming reaction. This sequence allows synthesis of bisTB derivatives, which are not accessible by known procedures. The described approach is a general new method for the preparation of bisTB derivatives from "troegerable" arylamines.
4,6-双(溴甲基)-N1,N3-双(叔-丁氧羰基)苯-1,3-二胺被介绍为一种通用的起始化合物,用于以极好的产率仅用两步就合成双Tröger's碱(bisTB)衍生物。合成序列包括将上述保护的二胺与芳胺反应,然后进行原位去保护,最后进行形成bisTB的最终反应。这个序列允许合成通过已知程序无法获得的双TB衍生物。所描述的方法是制备可“Tröger化”的芳胺双TB衍生物的一种通用新方法。
