実験手順
To a solution of 3.0 grams (0.009 mole) (±)-1-S-hexadecyl-2-O-methylthioglycerol in 200 milliliters of DCM and 1.0 milliliter (0.010 mole) of triethylamine was added 1.2 grams (0.012 mole) of methanesulfonyl chloride and the reaction stirred at room temperature for 24 hours. The reaction mixture was then extracted twice with 200 milliliter portions of water, twice with 200 milliliter portions of 5% HCl, once with 200 milliliters of saturated NaHCO3, and once with 200 milliliters of brine. The organic layer was dried over anhydrous sodium sulfate, filtered and evaporated in vacuo to yield 3.4 grams (89%) of a colorless oily residue. 1H-NMR (CDCl3): delta, 0.87(t, 3H, terminal methyl), 1.2-1.6[m, 28H, (CH2)14 ], 2.58(m, 2H, S--CH2), 2.62(m, 2H, CH--CH2 --S), 3.08(s, 3H, SO2 --CH3), 3.40-3.50(m, 4H, CH, CH3 --O), 4.35 (m, 2H, CH2 --OSO2).
