The reaction of (R)-O-benzylglycidol (I) with octadecanol (II) by means of NaH in hot DMF gives (R)-1-(benzyloxy)-3-(octadecyloxy)-2-propanol (III), which is methylated with methyl iodide and NaH in DMF yielding the corresponding methyl ether (IV). The debenzylation of (IV) with H2 over Pd/C in THF affords the primary alcohol (V), which is finally treated with POCl3/pyridine in CHCl3 and condensed with choline tosylate (VI) to furnish the target phosphorylcholine derivative.

该中间体在本合成路线中的序号:(IV)

Phosphitylation of 1D-2,4,5,6-tetra-O-benzyl-3-deoxy-myo-inositol (I) with benzyl tetraisopropylphosphorodiamidite (II) in the presence of diisopropylammonium tetrazolide produced phosphoramidite (III). Subsequent displacement of the remaining diisopropylamino group of (III) by 1-O-octadecyl-2-O-methyl-sn-glycerol (IV) gave phosphite ester (V), which was further oxidized to phosphate (VI) using tert-butyl hydroperoxide. Finally, removal of the benzyl protecting groups of (VI) was achieved by catalytic hydrogenation over Pearlman's catalyst.
