Procedure

A solution of 1-(10-undecenyl)-3,7-dimethylxanthine (4.3 g, 13 mmol), 4-methylmorpholine-N-oxide (1.942 g, 16.6 mmol) and potassium osmate dihydrate (9.5 mg; 0.026 mmol) in acetone (45 ml) and water (10 ml) was stirred for 6 hours. A solution of 20% aqueous sodium sulphite (12 ml) was added and the resulting mixture stirred for 30 minutes. The reaction mixture was extracted with 25% ethanol/dichloromethane (4×100 ml). The combined organic extracts were dried over anhydrous magnesium sulfate concentrated under reduced pressure and purified by flash chromatography over silica gel using a methanol (5%)/dichloromethane eluant, producing 3.6 g of 1-(10,11-dihydroxyundecanyl)-3,7-dimethylxanthine (76% yield).
