73196-87-9

2140-67-2

將化合物1（CAS: 73196-87-9，1.5 g，3.4 mmol）溶解于吡啶（2 mL）中，隨后加入氨水。反應(yīng)混合物在室溫下攪拌3小時(shí)，通過薄層色譜（TLC）監(jiān)測(cè)反應(yīng)進(jìn)度，直至顯示完全脫保護(hù)。反應(yīng)完成后，將溶劑在減壓下蒸發(fā)至干。粗產(chǎn)物通過從水中重結(jié)晶進(jìn)行純化，得到目標(biāo)產(chǎn)物9-((2R,3R,4S,5R)-3,4-二羥基-5-(羥甲基)四氫呋喃-2-基)-2-(二甲氨基)-1,9-二氫-6H-嘌呤-6-酮，產(chǎn)量0.68 g，收率65%。產(chǎn)物的結(jié)構(gòu)通過1H NMR、13C NMR和質(zhì)譜（ES-TOF）進(jìn)行確認(rèn)。1H NMR (DMSO-d6) δ: 3.06 (6H, s, NMe2), 3.48-3.63 (2H, m, 5'-CH2), 3.86 (1H, q, J = 4 Hz, H4'), 4.11 (1H, q, J = 4 Hz, H3'), 4.50 (1H, q, J = 4 Hz, H2'), 4.91 (1H, t, J = 5.4 Hz, OH5'), 5.15 (1H, d, J = 4.8 Hz, OH3'), 5.38 (1H, d, J = 6.1 Hz, OH2'), 5.71 (1H, d, J = 5.8 Hz, H1'), 5.92 (1H, s, H8), 10.69 (1H, bs, NH); 13C NMR δ: 38.1 (NMe2), 61.8 (C5'), 70.7 (C3'), 73.7 (C2'), 85.4 (C4'), 87.0 (C1'), 100.0, 116.4, 136.8 (C8), 151.1, 153.3, 157.7; MS (ES-TOF) m/z: 計(jì)算值 312.13，實(shí)測(cè)值 312.54。
