one-pot protocol to synthesize 2-aminophenol derivatives via a palladium-catalyzed C–H acetoxylation strategy with 5-nitropyrimidine as a directing group (DG), which can be easily preinstalled and readily removed under mild condition after the coupling. In addition, the transformation is operationally simple, has high functional group tolerance, and is amenable to gram-scale. Moreover, several examples
本文介绍了一种简便的一锅操作方案,该方法通过钯催化的CH5-H乙酰氧基化策略,以5-硝基嘧啶为导向基团(DG)来合成2-氨基苯酚衍生物,可以很容易地进行预安装,并在温和的条件下容易地将其除去。耦合。另外,该转化操作简单,具有高官能团耐受性,并且适合克规模。此外,几个例子表明,可以将5-硝基嘧啶的引入/去除和CH的羟基氧化序列整合到一个罐中。
