A method that allows salicylaldehydes to be efficiently transformed into meta-arylated phenol derivatives through a cascade oxidation/arylation/protodecarboxylation sequence is presented. We demonstrate that the aldehyde functional group can be used as a convenient removable directing group to control site selectivity in C-H activation. Aldehydes are easily introduced into the starting materials and
提出了一种通过级联氧化/芳基化/原脱羧序列将水杨醛有效转化为间芳基化苯酚衍生物的方法。我们证明醛官能团可以用作方便的可去除的导向基团来控制 CH 活化的位点选择性。醛很容易引入起始材料中,并且在 CH 官能化事件后该基团很容易裂解。
