Electrolysis of 1,3-diarylacetones with aliphatic amines in Bu4NI/CH3CN to racemic Favorskii amides via benzyl group rearrangement has been developed. The electroconversion is easily conducted in a simple undivided cell under constant-current conditions at room temperature. The electrocatalytic Favorskii rearrangement of 1,3-diarylacetones including electron-withdrawing substituents was favored and
已开发了通过苄基重排将1,3-二芳基
丙酮与Bu 4 NI / CH 3 CN中的脂肪族胺电解成外消旋的Favorskii酰胺。在室温下恒定电流条件下,在简单的不分格电池中可以轻松进行电转换。包括吸电子取代基的1,3-二芳基
丙酮的电催化Favorskii重排是有利的,并且α-苄基酰胺具有良好的产率。当使用几种不对称酮作为底物时,观察到具有中等区域选择性的这种重排。该
化学方法还提供了在酰胺的α-位上构建手性中心的有效方法。
