A very convenient and efficient modular approach for the synthesis of vicinal diamines containing axial chiral 1,1'-binaphthyl from 1,2-diaminoethane by Pd-catalyzed N-arylation reactions has been developed. The resulting chiral diamines could be easily converted into NHC precursors, imidazole salts, in good yields.
已开发出一种非常方便、高效的模块方法，通过钯催化的 N-芳基化反应，从 1,2-二氨基乙烷合成含有轴向手性 1,1'-联萘的偕二胺。所得手性二胺可轻松转化为 NHC 前体、咪唑盐，产率良好。
