A TfOH-promoted tandemsynthesis of 1,3-disubstituted naphthalenes is developed via a directed-aldol reaction and a Friedel–Crafts reaction. Two new C–C bonds and one new benzene ring are created efficiently in one pot due to the discovery of a TfOH-promoted highly chemoselective directed-aldol reaction between two different ketones with α-hydrogens.
