The novel CuCl 2 ‐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.
