An intramolecular cyclization reaction of hexafluoro-isopropyl α,β-alkenyl sulfonates was investigated. Catalytic amount of NaOAc was found to accelerate the addition of α-carbon of hexafluoroisopropyl moiety to β-position of unsaturated sulfonates, generating a series of trifluoromethylated five-memberring of sulfonates in moderate yields.

Key words: sultones, trifluoromethyl, intramolecular cyclization
