反応手順
A solution of 1-(7-octenyl)-3,7-dimethylxanthine (1.00 g, 4.5 mmol), 4-methylmorpholine-N oxide (553 mg, 4.7 mmol), and a 2.5% solution of osmium tetroxide in t-butanol (3 drops) in acetone (25 mL) and water (20 mL) was stirred for 4 days. After addition of a saturated aqueous solution of sodium hydrosulfite (10 mL) and 30 minutes of continued stirring, the reaction mixture was added to water (50 mL) and extracted with 20% ethanol/dichloromethane (3×50 mL). Evaporation of the solvent under vacuum yielded an off-white residue. The residue was recrystallized in ethanol, yielding 726 mg (63% yield) 1-(7,8-dihydroxyoctyl)-3,7-dimethylxanthine (inventive compound no. 1538) as a white solid.
