A general and straightforward synthesis of anthraquinones was developed, in which diallylation of 1,4-naphthoquinones, followed by Ring Closing Metathesis (RCM) of the resulting diallylnaphthoquinones with Grubbs’ catalyst and subsequent dehydrogenation using Pd/C afforded the desired anthraquinones with regiocontrol of substituents and in good yields.
我们开发了一种通用而简单的蒽醌类化合物合成方法,即先将 1,4-naphthoquinones 进行二烯丙基化,然后在 Grubbs 催化剂的作用下将生成的二烯丙基萘醌进行闭环合成 (RCM),随后使用 Pd/C 进行脱氢反应,这样就能以良好的收率获得所需的蒽醌类化合物,同时还能对取代基进行区域控制。
