Abstract
The synthesis of 2,4-disubstituted-1-naphthols has been developed employing photomediated C-C bond cleavage (UV-LED 390 nm) of cyclopropane fused-indanones generated in situ from the reaction between indenones and trimethylsulfoxonium chloride under basic conditions at room temperature. Seventeen substrates were examined in this study. The results showed that indenone precursors containing aryl substituents could smoothly provide the desired products in up to 81% yield.

Abstract
A TfOH-promoted tandem synthesis 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.
