meta‐substituted phenols in which a single palladium catalyst accomplishes a Suzuki–Miyaura cross‐coupling between a β‐chlorocyclohexenone and an arylboronic acid, and oxidation of the resulting cyclohexenone to the corresponding phenol upon introduction of a terminal oxidant and electron transfer mediator. Notably, this method also allows ready access to ortho, meta‐disubstituted phenols, sterically congested
我们报告了一种合成间位取代酚的新方法,其中单个钯催化剂完成了β-氯代环己烯酮和芳基硼酸之间的Suzuki-Miyaura交叉偶联,并在引入环戊烯酮之后将所得环己烯酮氧化为相应的苯酚末端氧化剂和电子转移介体。值得注意的是,这种方法还可以方便地使用邻位,间-二取代的苯酚,空间上拥挤的联芳基苯酚以及更高度取代的苯酚。
