aromatic amines is of continuous interest in chemistry. An exceptionally versatile three‐component reaction that directly transforms inexpensive nitro compounds, boronic acids, and trialkyl phosphites into tertiary aromatic amines has been realized. The reaction tolerates alkyl and aryl substituents on the nitro and boronic acid moieties, as well as functionalized phosphites. No transition‐metal catalysis
芳族胺的合成在化学上一直受到关注。已经实现了一种极其通用的三组分反应,该反应可将廉价的硝基化合物,硼酸和亚磷酸三烷基酯直接转化为叔芳族胺。该反应容许硝基和硼酸部分上的烷基和芳基取代基以及官能化的亚磷酸酯。不需要过渡金属催化。该方法与其他经典的金属催化合成方法正交,因为它可以容忍卤素的存在,并且还可以合成功能化的化合物,例如α-氨基酯衍生物。
