In an enantioselective fluorination of allylic alcohols under chiral anion phase-transfer conditions, an in situ generation of a directing group proved crucial for achieving effective enantiocontrol. In the presence of such a directing group, a range of acyclic substrates underwent fluorination to afford highly enantioenriched α-fluoro homoallylic alcohols.
