实验步骤: 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 mol) 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. Crude Compound 21 (1.16 g) was dissolved in CH2Cl2 (10 mL) after which trifluoroacetic acid (2 mL) was added. The reaction mixture was stirred for 5 min and excess TFA was quenched by adding solid NaHCO3 until effervescence ceased. The mixture was diluted with H2O (10 mL), extracted with CH2Cl2 (2×50 mL) and the combined organic phases were dried (MgSO4), concentrated and subjected to silica-gel column chromatography [eluent: hexane/ethyl acetate, 80/20, v/v] to give glycerol derivative Compound 22 (0.28 g, 42%) as an oil. The reaction was left was removed by co-evaporation with toluene (2×5 mL) After 16 hours was added 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) concentrated

实验步骤: To a mixture of NaH (4.8 g, 120 mmol) and NaI (0.2 g) in dry DMF (20 mL) was added solketal (5.0 mL, 40 mmol) dropwise over a 30 min period. Once the effervescence had stopped, oleyl tosylate (Compound 13) (16.9 & 40 mmol) was added and the reaction mixture was left for 3 days at 50° C. Then, H2O (10 mL) was added and the mixture was extracted with diethyl ether (2×100 mL), the combined organic phases were dried (MgSO4) and evaporated to dryness. The residue was taken up in THF (150 mL), 2M HCl was added until the solution tuned turbid and the reaction was left to stir for 16 hours. The mixture was concentrated and subjected to silica-gel column chromatography [eluent: ethyl acetate/hexane, 50/50, v/v] to give 1-O-oleyl-rac-glycerol (Compound 20) as an oil. the mixture was extracted with diethyl ether (2×100 mL) the combined organic phases were dried (MgSO4) evaporated to dryness 2M HCl was added until the solution the reaction was left The mixture was concentrated
