## Abstract The stereoselective rearrangement of tetrahydrofuran or tetrahydropyran rings having a phenylsulfanyl group in an __exo__ position, __via__ the intermediate thiiranium ions, is reported. The 5‐ or 6‐__exo__‐tet cyclization of hydroxy sulfides gave the kinetic products while the 6‐__endo
