A solution of 3-(5-hexenyl)-1-methyluracil (598 mg, 2.9 mmol), 4-methylmorpholine-N oxide (408 mg, 3.5 mmol), and a 2.5% solution of osmium tetroxide in t-butanol (3 drops) in acetone (15 ml) and water (5 ml) was stirred for 3 days. Saturated aqueous sodium hydrosulfite solution (10 ml) was added and the mixture was stirred for 15 minutes. Water (50 ml) was added and the mixture was extracted with 20% ethanol-dichloromethane (4×40 ml). The combined organic layers were dried over sodium sulfate and the solvents were evaporated under vacuum to give 3-(5,6-dihydroxyhexyl)-1-methyluracil (461 mg, 66% yield) as a colorless oil.
