実験手順

A solution of the compound 8 (6.5 g, 4.84 mmol) and dichloromethyl methyl ether (2.18 ml, 24.2 mmol) in CHCl3 (60 ml) at 0° C. was treated with ZnCl2 (1.0 M in ether; 2.41 ml, 2.41 mmol) and then allowed to warm slowly and stir at room temperature overnight. The reaction mixture was diluted with EtOAc, washed with saturated aq. NaHCO3, dried (Na2SO4) and then concentrated. The light yellow oil obtained was purified by flash chromatography on silica gel eluting with 10% EtOAc-hexanes to give 5.4 g (88%) of 2-deoxy-4-O-diphenylphosphono-3-O-[(R)-3-tetradecanoyloxytetradecanoyl]-6-O-(2,2,2-trichloro- 1,1 -dimethylethoxycarbonyl)-2-(2,2,2-trichloroethoxycarbonylamino)-α-D-glucopyranosyl chloride (compound 9) as an amorphous solid: 1H NMR (CDCl3) δ0.88 (˜t, 6H), 1.1-1.6 (m, 42H), 1.78 (s, 3H), 1.88 (s, 3H), 2.18 (t, 2H, J=7.6 Hz), 2.34-2.52 (m, 2H), 4.2-4.4 (m, 4H), 4.70 (d, 1H, J=12 Hz), 4.73 (d, 1H, J=12 Hz), 4.83 (˜q, 1H, J=9 Hz), 5.09 (m, 1H), 5.51 (˜t, 1H J=10 Hz), 5.79 (d, 1H, J=8.0 Hz), 6.26 (d, 1H, J=3.6 Hz), 7.1-7.4 (m, 10H).
