Abstract: A new efficient method for preparingo-L-α-glycerylphosphoryl-L-serine was presented.D-α,β-isopropylidene glycerol was phosphorylated with phenylphosphoryl dichloride and the resultingo-D-α,β-isopropylidene glycerylphenylphosphoryl chloride was esterified withN-tert-butoxycarbonyl-L-serine ethyl ester in the presence of pyridine to give acetoneL-α-glycerylphenylphosphoryl-N-tert-butoxycarbonyl-L-serine ethyl ester. Finally, the protective groups were removed by two-step hydrolysis while strictly controlling pH value. The reaction to produce (1,2), (5, 6)-diisopropylidene-D-mannitol, which is the key precursor for the preparation ofD-α,β-isopropylidene glycerol, was monitored by using gas chromatography-mass spectrometer in order to obtain an optimum yield of 65%. All compounds were characterized through elemental analysis, infrared spectra,1H,13C,31P-nuclear magnetic resonance spectra and mass spectra.
