Palladium-catalyzed, hydroxy-group-directed C–H arylation of [1,1′-biphenyl]-2-ols with chloroarenes was performed. The reaction showed a broad substrate scope and was successfully applied to pharmaceuticals containing a chloro group. Using 2-heteroarylphenols instead of [1,1′-biphenyl]-2-ols also yielded the desired products. The arylated product was further transformed into a triphenylene derivative
[1,1'-联苯]-2-醇与氯芳烃进行钯催化、羟基导向的 C-H 芳基化反应。该反应显示出广泛的底物范围,并成功应用于含有氯基的药物。使用 2-杂芳基苯酚代替 [1,1'-联苯]-2-醇也产生了所需的产物。芳基化产物进一步转化为苯并菲衍生物。 全尺寸图片
