Methyl iodide → 1-o-Oleyl-2-o-methyl-3-o-trityl glycerol

참여 물질

반응 단계

Diol Compound 20 (2.0 g, 5.97 mmol) was added dropwise to a solution of trityl chloride (1.66 g, 6.0 mmol) in anhydrous pyridine (10 mL). The reaction was left to stir for 16 hours after which the solvent was removed by co-evaporation with toluene (2×5 mL). Then, part of the residue (1.0 g, 1.7 mmol) was added dropwise to a suspension of NaH (0.14 g, 3.4 mmol) in THF (50 mL), followed by the addition of MeI (0.22 mL, 3.4 mmol). After 16 hours, TLC analysis showed that the reaction had gone to completion and H2O (5 mL) was added followed by concentration of the reaction mixture. The residue was partitioned between H2O (20 mL) and diethyl ether (100 mL), the organic extract was washed with sat. NaHCO3 (10 mL), dried (MgSO4) and concentrated to give 1-O-oleyl-2-O-methyl-3-O-trityl glycerol (Compound 21) as an oil.
