A Highly Regioselective Synthesis of Polysubstituted Naphthalene Derivatives through Gallium Trichloride Catalyzed Alkyne-Aldehyde Coupling

A convenient synthesis of polysubstituted naphthalenes 3 involves the gallium trichloride catalyzed coupling of aromatic alkynes 1 and phenyl acetaldehydes or ketones 2 in dichloromethane. The reaction is highly regioselective.
