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.
