Reported herein is the one‐pot synthesis of trifluoromethylated amines at room temperature using the bench‐stable (Me4N)SCF3 reagent and AgF. The method is rapid, operationally simple and highly selective. It proceeds via a formal umpolung reaction of the SCF3 with the amine, giving quantitative formation of thiocarbamoyl fluoride intermediates within minutes that can readily be transformed to N‐CF3
本文报道了使用实验室稳定的 (Me 4 N)SCF 3试剂和 AgF 在室温下一锅合成三氟甲基化胺。该方法快速、操作简单、选择性高。它通过 SCF 3与胺的正式 umpolung 反应进行,在几分钟内定量形成硫代氨基甲酰氟中间体,该中间体可以很容易地转化为 N-CF 3 。温和性和高官能团耐受性使得该方法对于在胺上后期引入三氟甲基基团非常有吸引力,正如本文针对一系列药学相关药物分子所证明的那样。
