Hexafluoroisopropanol has been demonstrated as the versatile promoter for redox-neutral α-C(sp3)-H functionalization of cyclic amines via the cascade [1,5]-hydride transfer/cyclization strategy. A wide range of cyclic amines are functionalized into bioactive tetrahydroquinolines, quinazolines, benzoxazines, and benzotriazepines in moderate to excellent yields. This protocol features additive-free conditions
六氟异丙醇已被证明是通过级联[1,5]-氢化物转移/环化策略用于环胺的氧化还原中性α-C(sp3)-H官能化的多功能促进剂。多种环胺以中等至极好的收率被官能化为具有生物活性的四氢喹啉,喹唑啉,苯并恶嗪和苯并三氮杂ze。该协议具有无添加剂条件,操作简便和广泛的基材范围。
