Versuchsvorschrift
In 30 ml of xylene was dissolved 854 mg (5.3 mmol) of 2-O-tetrahydrofuranylglycerol. To this was added 1.78 g (15.9 mmol) of t-butoxypotassium under argon gas and the mixture was stirred for 5 minutes. Then, 10 ml of a solution of 6.71 g (15.9 mmol) oleyl p-toluenesulfonate in xylene was added dropwise and the mixture was stirred under reduced pressure (20-30 mmHg) at ambient temperature for 30 minutes and further at 50° C. for 1 hour. This reaction mixture was poured in ice-water and extracted with ether, and the extract was washed with water, dried, and concentrated. The residue was purified by column chromatography (silica gel/chloroform) to provide 628 mg (18%) of 1,3-O-dioleyl-2-O-tetrahydrofuranylglycerol as yellow oil.
