1-octadecoxyoctadecane

反応条件: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Distearyl ether was synthesized by reacting stearyl bromide (Sigma) with PEG-900 in the presence of potassium hydroxide. Stearyl bromide (4.168 g in 10 ml toluene) was slowly added with stirring to 4.64 g of PEG-900 in 10 ml of toluene at 45° C. The mixture was then stirred at 60° C. for 30 min. and refluxed for 6 hrs. The final product was treated with charcoal, filtered and isolated from toluene. Distearyl ether was synthesized refluxed for 6 hrs filtered isolated from toluene

実験手順: To a stirred suspension of NaH (80%; 0.55 g, 17.4 mmol, 2 equiv) in THF (20 ml) was added dropwise a solution of (R)-glycerol acetonide 1 (1.15 g; 1 equiv) in THF (20 ml). After that octadecyl bromide (5.8 g, 17.4 mmol, 2 equiv) dissolved in THF (25 ml) was added dropwise and the mixture obtained was stirred overnight at 80° C. The reaction mixture was cooled to 0° C. and water was added. The resulting mixture was concentrated and the residue was extracted with water and diethyl ether and the combined extracts were dried (MgSO4). The crude product obtained was further purified by flash column chromatography (10% ethyl acetate-n-hexane) to yield the title compound 1b (2.03 g, 5.28 mmol, 61%). was added dropwise the mixture obtained The reaction mixture was cooled to 0° C. The resulting mixture was concentrated the residue was extracted with water and diethyl ether the combined extracts were dried (MgSO4) The crude product obtained was further purified by flash column chromatography (10% ethyl acetate-n-hexane)
