実験手順

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.
