A new method has been developed to obtain 2-nitroamines by an indium-promoted reaction of bromonitromethane with a variety of imines. On the strength of these results, the reaction was also performed with 2-bromo-2-nitropropanes to afford 2,2-dialkyl-2-nitroamines. Moreover, the indium-mediated reaction of 1-bromo-1-nitroethane and imines afforded 1-methyl-2-nitroamines with remarkably high anti selectivity
已开发出一种通过溴硝基甲烷与多种亚胺的铟促进反应获得 2-硝基胺的新方法。基于这些结果,该反应还与 2-溴-2-硝基丙烷一起进行,得到 2,2-二烷基-2-硝基胺。此外,铟介导的 1-溴-1-硝基乙烷和亚胺反应提供了具有非常高的抗选择性的 1-甲基-2-硝基胺。手性糖衍生亚胺的使用为相应的 2-硝基胺提供了优异的立体选择性。
