A new straightforward procedure has been developed for the synthesis of polysubstituted naphthalene derivatives. The reaction of alpha-aryl-substituted carbonylcompounds with terminal or internal alkynes in the presence of TiCl4 regioselectively generates substituted naphthalene derivatives in good to excellent yields.
