Synthesis of Fluoroalkylated Allylic-β-hydroxyesters and Fluoroalkylated ,β,γ-Epoxy Esters from Ethyl 3-Hydroxy-4-pentenoate

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.
