A γ-Fluoro β-Acetoxypropyl Sulfonium Salt as an Equivalent of a (Fluoromethyl)vinyl Sulfonium Salt: Reagent for the Facile Synthesis of Monofluoromethylated Cyclopropanes or Aziridines

Abstract

<jats:p>A β-monofluoromethylated vinyl sulfonium salt, prepared in situ from a precursor γ-fluoro β-acetoxypropyl sulfonium salt under mild basic conditions, reacted with a lvariety of active methylene compounds or a primary sulfone amide under basic conditions to provide the corresponding monofluoromethylated three-membered rings in good-to-excellent yields. This new sulfonium reagent should permit easy access to a variety of important monofluoromethylated organic compounds.</jats:p>
