title: Enantioselective synthesis of beta-trifluoromethyl-beta-lactones via NHC-catalyzed ketene-ketone cycloaddition reactions.
abstract: The highly diastereo- and enantioselective synthesis of beta-trifluoromethyl-beta-lactones bearing two contiguous stereocenters was realized by chiral N-heterocyclic carbene-catalyzed formal cycloaddition reaction of alkyl(aryl)ketenes and trifluoromethyl ketones.
