실험 절차
To 1-(5-hexenyl)-3,7-dimethylxanthine (1.07 g, 4.1 mmol) and 4-methylmorpholine-N-oxide (1.44 g, 12.3 mmol) in water (20 ml) and acetone (10 ml) was added 2.5% solution of osmium tetraoxide in t-butanol (6 drops). After stirring for 48 hours, the mixture was treated with 20% aqueous sodium dithionite solution (20 ml). After 2 minutes, the mixture was extracted with 25% ethanol-dichloromethane (3×30 ml). The combined extracts were dried over magnesium sulfate and the solvents were evaporated under vacuum to give 1-(5,6-dihydroxyhexyl)-3,7-dimethylxanthine (750 mg, 62% yield) as a white powder.
