intermediates. This strategy allows the expansion of SO2F2-mediated one-pot processes to include radical reactions, where the alkyl halides can also be exploited in the one-pot deoxygenation of primary alcohols under mild conditions (52–95% yield). This strategy can also enhance the scope of substitutions to nucleophiles that are previously incompatible with one-pot SO2F2-mediated alcohol activation and enables
硫酰氟是用于一键活化和衍生化
脂肪醇的有价值的试剂,但是高反应性的烷基
氟硫酸烷基酯中间体限制了可以进行的反应类型以及反应范围。在本文中,我们报道了SO 2 F 2介导的醇取代和脱氧方法,该方法依赖于
氟代硫酸盐向烷基卤化物中间体的转化。该策略允许扩展SO 2 F 2介导的一锅法包括自由基反应,其中烷基卤也可在温和条件下(52-95%的收率)用于伯醇的一锅法脱氧。这种策略还可以扩大以前与一锅SO 2 F 2介导的醇活化不相容的亲核试剂的取代范围,并能够以54-95%的产率取代伯醇和仲醇。手性仲醇具有高度立体特异性(90-98%ee)的双亲核取代,且整体保留构型。
