A new synthetic method to substituted alpha-carboxy-gamma-fluorothiophenes 2F is reported. They were prepared by the reaction between two equivalents of methyl thioglycolate anion and alpha-fluoro-beta-(phenylthio)enones (or -enals) 1F, in DMSO (70 degrees C) in yields ranging from 41% to 85%. We show from the reaction of (Z)-alpha-fluoro-beta-(phenylthio)but-enone 1aF, that cyclisation to fluorothiophene 2aF occurs via the formation of stable enolates of alpha-fluoro-beta-(dithianyl)butanone.
