A simple and efficient synthetic protocol is developed for the preparation of heterodentate azomethine ligands bearing various functionalities, by Schiff condensation of dialdehydes with monoprotected diamine followed by reduction of the azomethine bond and deprotection. The efficient procedure of obtaining N-tert-butoxycarbonyl-protected o-phenylenediamine in large scale is also elaborated.
通过二醛与单保护二胺的希夫缩合,然后还原偶氮甲碱键并脱保护,开发了一种简单有效的合成方案,用于制备具有各种功能的异齿偶氮甲碱配体。还详细阐述了大规模获得N-叔丁氧基羰基保护的邻苯二胺的有效方法。
