The novel CuCl2‐catalyzed title reaction of enynes has been developed for synthesizing substituted naphthoquinones (see scheme; DMA=dimethylacetamide). The method represents the first example of a copper‐catalyzed enyne oxidative cyclization for constructing 1,4‐naphthoquinones by the incorporation of two oxygen atoms into the organic framework from molecular oxygen and water.
已开发出新型的烯炔的CuCl 2催化标题反应,用于合成取代的萘醌(参见方案; DMA =二甲基乙酰胺)。该方法代表了一个铜催化的烯炔氧化环化的第一个例子,该环化反应是通过将两个氧原子从分子氧和水引入有机骨架来构建1,4-萘醌。
