In this report, we provide for the first time a facile, efficient, and stereoselective synthesis of 1-[5-O-(tert-butyldiphenylsilyl)-2, 3-dideoxy-3-C-formyl-β-D-erythro-pentofuranosyl] thymine (12), using an intermolecular radical C-C bond formation reaction. The utility of this compound for antisense application is discussed and, as an extension, 12 was converted into 1-[2,3-dideoxy-3 -C-(hydroxymethyl)-β-D-erythro-pentofuranosyl]thymine (14), a potent antiviral and antitumor agent.
在本报告中,我们首次利用分子间自由基 C-C 键形成反应,简便、高效、立体选择性地合成了 1-[5-O-(叔丁基二苯基硅烷基)-2,3-二脱氧-3-C-甲酰基-δ²-D-赤式戊呋喃糖基]胸腺嘧啶(12)。讨论了这种化合物在反义应用中的效用,作为延伸,12 被转化为 1-[2,3-二脱氧-3-C-(羟甲基)-δ-D-赤式戊呋喃糖基]胸腺嘧啶(14),这是一种有效的抗病毒和抗肿瘤药物。
