Alkyl arylethers are an important class of compounds in medicinal and agricultural chemistry. Catalytic C(sp3)−O cross‐coupling of alkyl electrophiles with phenols is an unexplored disconnection strategy to the synthesis of alkyl arylethers, with the potential to overcome some of the major limitations of existing methods such as C(sp2)−O cross‐coupling and SN2 reactions. Reported here is a tandem
烷基芳基醚是药物和农业化学中重要的一类化合物。烷基亲电试剂与酚类的催化C(sp 3)-O交叉偶联是烷基芳基醚合成的未探索的断开策略,具有克服现有方法(例如C(sp 2)-的某些主要局限性)的潜力O交叉偶联和S N 2反应。本文报道了串联的光氧化还原和铜催化以实现烷基N的脱羧C(sp 3)-O偶联‐羟基邻苯二甲酰亚胺(NHPI)与酚在温和的反应条件下形成的酯。该方法用于使用容易获得的烷基羧酸(包括许多天然产物和药物分子)合成各种烷基芳基醚。证明了在范围和功能组对现有方法的容忍度方面的互补性。
