The development of new general methods for the synthesis of chiral fluorine-containing molecules is important for several scientific disciplines. We herein disclose a straightforward method for the preparation of chiral organofluorine molecules that is ba

(Chemical Equation Presented) A mild and efficient procedure to synthesize α-fluoro- and α,α-difluoroimines was developed. Various N-alkylimines derived from acetophenones were successfully monofluorinated using NFSI (N-fluorobenzenesulfonimide) in a mixture of CH3CN and DMF at 0°C. Alternatively, the same procedure without DMF gave rise to difluorinated imines when performed at room temperature. The obtained α- and α,α-difluorinated imines were subsequently reduced to give the corresponding β-fluoro- and β,β-difluoroamines in good yield.

α-Fluoroketones 6 are synthesized in good yields and high enantiomeric excesses (ee = 87-≥96%) from the corresponding simple cyclic and acyclic ketone precursors. The procedure involves a regio- and diastereoselective electrophilic fluorination of enantio
