Tetrahydrofuran → 4-Dodecanoxy-2-triethylsilylfuran

참여 물질

반응 단계

A solution of 4-hydroxymethyl-2-triethylsilylfuran (Compound 1, 160 mg, 0.75 mmol) in tetrahydrofuran (0.5 ml) was added to a suspension of potassium hydride (33 mg, 0.83 mmol) in tetrahydrofuran (1 ml) at room temperature. When all the potassium hydride disappeared, 1-iodododecane (0.37 ml, 1.5 mmol) was added. Stirring was continued for 4 days at room temperature. The reaction mixture was quenched with water. Extraction (ethyl ether) and evaporation of the dried (magnesium sulfate) extracts gave an oil, which was purified by flash chromatography on silica using 5% ethyl ether/hexane. Fractions with Rf of about 0.65 on evaporation gave the titled ether as a pale yellow oil.
