The synthesis of diethyl l,l-difluoro-2-oxoalkylphosphonates has been reported by a cerium-mediated reaction between diethyl 1-lithio-1,1-difluoromethylphosphonate and ethyl esters at low temperature in THF. After acidic quench at low temperature, diethyl I, I -difluoro-2-oxoalkyIphosphonates are isolated in good yield.- Addition of diethyl 1-lithio-1,1-difluoromethylphosphonate to di-ferf-butyl oxalate at low temperature in THF affords exclusively the addition product, an unusually stable ferf-butyl hemiketal. When a solution of this material is heated at reflux in ( ,1 f, or chromatographed on silica gel, only a few percent is converted to the hydrate. This conversion is best effected by dissolving the hemiketal in MeCN followed by reaction with aqueous Nal ICO . Subsequent azeotropic dehydration with CgHg affords diethyl l,l-difluoro-2-oxo-2-(fert-butoxycar-bonyl)ethylphosphonate. 5... [Pg.343]
