The fluoroalkylation reaction of chiral 4-pentenoic acids with RFI was investigated. In aqeous acetonitrile, chiral 4-pentenoic acids reacted with fluoroalkyl iodide initiated by sodium dithitionite in the presence of base to afford chiral fluorine-containing γ-butyrolactones. The structures of the compounds were comfirmed by NMR, IR, and HRMS techniques. The configurations were ascertained by X-ray single crystal diffraction.

Key words: chiral enoic acid, fluoroalkylation, sodium dithionite, chiral fluorine-containing γ-buty- rolactone
