Participants

Procedure

To a stirred solution of 4-hydroxymethyl-2-trimethylsilylfuran (0.288 g., 1.70 mmol) and pyridine (0.214 g., 2.55 mmol) in 30 ml dry tetrahydrofuran at 0 degrees was added lauroyl chloride (0.408 g., 1.86 mmol). This solution was allowed to warm to room temperature, stirred 30 minutes, and partitioned between ethyl ether and 5% sodium bicarbonate solution The organic portion was washed with aqueous cupric sulfate solution, water, saturated sodium chloride solution, dried over magnesium sulfate, filtered and concentrated to a colorless oil. This material was purified by flash chromatography (silica, 5% ethyl ether/petroleum ether) to give the desired ester.
