We report a simple protocol for the synthesis of α-fluoro-β-aminophosphonates by the regioselective fluorination of α-hydroxy-β-aminophosphonates under mild conditions. The fluorination reactions were mediated by the PyFluor reagent and occurred with the retention of configuration. The main products of this reaction were a series of α-fluoro-β-aminophosphonates, which can be used as precursors in the preparation of medicinally important compounds (e.g., dipeptide analogues).

Described are D-(threo)-1-aryl-2-acylamido-3-fluoro-1-propanols, methods for their preparation, and methods for their use as antibacterial agents. Of particular interest are D-(threo)-1-p-nitrophenyl-2-dichloroacetamido-3-fluoro-1-propanol and D-(threo)-1-p-methylsulfonylphenyl-2-dichloroacetamido-3-fluoro-1-propanol and the corresponding 2-difluoroacetamido compounds which are the 3-fluoro-3-deoxy analogs of chloramphenicol, thiamphenicol, difluoroacetyl analog of chloramphenicol, and of fluorthiamphenicol, respectively, and which are active both against organisms sensitive to and resistant to the parent amphenicol antibiotics. Other particularly valuable antibacterial agents include the corresponding 2-(chlorofluoroacetamido)-, 2-dichlorodeuterioacetamido, 2-difluorodeuterioacetamido-, and the 2-(chlorofluorodeuterioacetamido)- derivatives of the foregoing 3-fluoro-3-deoxy amphenicols.
