Reaction Conditions

Reaction Steps

To a suspension of 2-iodoadenosine 1 (10.0 g, 25.4 mmol) in acetone (200 ml) cooled to 0° C. was added dropwise 70% perchloric acid (4.0 mL), resulting in an exotherm of about 5° C. The resultant colorless solution was allowed to warm to room temperature over 30 minutes, then stirred for a further 45 minutes. 1M Na2CO3 (50 mL) was added, resulting in solids precipitating. This was followed by the careful portionwise addition of water (300 mL) with stirring until all solids had dissolved. The mixture was extracted with three portions of CH2Cl2. The combined organics were washed with brine, dried (Na2SO4), filtered, and evaporated to afford Compound 2 (10.26 g, 93%) as a colorless solid. 1H-NMR (600 MHz, DMSO d6): 1.32 (s, 3H), 1.54 (s, 3H), 3.54 (m, 2H), 4.19 (m, 1H), 4.93 (dd, 1H), 5.05 (t, 1H), 5.27 (dd, 1H), 6.05 (d, 1H), 7.74 (bs, 2H), 8.28 (s, 1H); 13C-NMR (150 MHz, DMSO d6): 25.45, 27.08, 85.69, 86.09, 88.44, 92.59, 114.92, 120.39, 142.47, 151.08, 157.20, 173.14. LRMS (ES): m/z=434.0 (M+H, 100%).
