Copper-catalyzed intramolecular oxidative 6-exo-trig cyclization of 1,6-enynes with H2O and O2.

CuCl‐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 oxyg... Full description
