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,高效的模块化方法,可通过Pd催化的N-芳基化反应从1,2-二氨基乙烷合成含轴向手性1,1'-联萘基的邻位二胺。所得手性二胺可以容易地以良好收率转化为NHC前体咪唑盐。
