Abstract
α-Fluoro-β-lactones have been synthesized and isolated for the first time from α-fluoro-β-hydroxy acids by using the couple TsCl/DMAP as lactonization agent. A detailed description of the synthesis and spectroscopic properties of α-fluoro-β-lactones is presented. Preliminary results indicate that thermolysis of these new β-lactones produces 1-fluoroalkenes.
