Abstract
The synthesis of the (alpha,alpha-difluoroalkyl)phosphonate analogue o f L-phosphoserine, 5, in a form appropriate for solid phase peptide sy nthesis, is reported. Two independent routes are described, starting f rom L-serine or (R)-isopropylideneglycerol. In each case, PCF2-C bond formation is achieved by triflate displacement with diethyl lithiodifl uoromethylphosphonate.
