摘 要:A sequential transformation of fluoroalkylated adducts obtained from ethyl 3-hydroxy-4-pentenoate with fluorinated iodides was reported. The dehydrohalogenation of adducts was favored to give fluoroalkylated unsaturated β-hydroxy esters in the presence of triethylamine. And intramolecular SN42 reaction products, fluoroalkylated β,γ-epoxy esters, were obtained in 10% aqueous sodium carbonate solution.A sequential transformation of fluoroalkylated adducts obtained from ethyl 3-hydroxy-4-pentenoate with fluorinated iodides was reported.
