Abstract
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.
