Fluorinated enol ethers: their synthesis and reactivity

Thanks to the beneficial effect of fluorine substitution on the pharmacokinetic properties of molecules, an ever increasing number of marketed drugs incorporate a fluorine atom into their structure. As a consequence, the synthesis of fluorinated molecules has become a very active research field. Among the numerous approaches, fluorinated enol ethers are valuable building blocks that allow the introduction of a fluoro- or difluoromethyl group through a wide variety of reactions. The present review lists different methods for their preparation and sums up their numerous synthetic applications. This review sums up the methods for the preparation of fluorinated enol ethers as well as their numerous synthetic applications.
