一般步骤:在-78℃条件下,向含有6.0 g(11.1 mmol)(2R,3R,4R,5R)-2-(乙酰氧基甲基)-5-(6-氯-2-碘-9H-嘌呤-9-基)四氢呋喃-3,4-二基二乙酸酯的烧瓶中加入100 mL液态NH3,持续搅拌6小时。随后,将反应混合物缓慢升温至室温,并过夜蒸发NH3,得到棕色油状物。通过热异丙醇结晶纯化产物,得到2-碘腺苷(产率80%,熔点143-145°C)。薄层色谱分析(20% MeOH/CHCl3)显示Rf值为0.6。1H NMR(300 MHz, DMSO-d6)δ 8.24(s, 1H), 7.68(s, 2H), 5.75(d, J = 6.16 Hz, 1H), 5.42(d, J = 5.40 Hz, 1H), 5.16(d, J = 4.62 Hz, 1H), 4.99(t, J = 5.39 Hz, 1H), 4.67(d, J = 4.81 Hz, 1H), 4.06(d, J = 3.37 Hz, 1H), 3.89(m, 1H), 3.54(m, 2H)。
