conversion of substituted 1,3-cyclohexanediones to the alkyl ethers of resorcinol using a Pd/C–ethylene system is reported. In these reactions, ethylene works as a hydrogen acceptor. The efficient synthesis of resveratrol was achieved using this protocol as a key step. In addition, the direct formation of substituted resorcinols was carried out by adding K2CO3 into the reaction media.
据报道,使用Pd / C-乙烯系统将取代的1,3-环己二酮转化为间苯二酚的烷基醚。在这些反应中,乙烯充当氢受体。使用该方案作为关键步骤,可实现白藜芦醇的有效合成。另外,通过向反应介质中加入K 2 CO 3来直接形成取代的间苯二酚。
