Abstract

The direct ring construction of amides with alkynes catalyzed by palladium acetate with cheap oxidant under an air atmosphere has been realized. A variety of novel highly substituted naphthalenes 3a–3l have been prepared chemo- and regioselectively in 55–97% yields under mild conditions. Product 3j emits intense blue luminescence peaked at 435 nm with a good blue purity.
