A novel approach toward the synthesis of 3-methylnaphthalenes is achieved by the reaction of 3-methylene-5,5-disubstituted tetrahydrofurans derived from methylenetriphenylphosphorane, 1,1-disubstituted epoxides and paraformaldehyde with trimethylsilyl trifluoromethanesulfonate in the presence of diisopropylethylamine.
