  A General and Enantioselective Approach to Pentoses: A Rapid Synthesis of PSI-6130, the Nucleoside Core of Sofosbuvir

  摘要：

  An efficient route towards biologically relevant pentose derivatives is described. The de novo synthetic strategy features an enantioselective alpha-oxidation reaction enabled by a chiral amine in conjunction with copper(II) catalysis. A subsequent Mukaiyama aldol coupling allows for the incorporation of a wide array of modular two-carbon fragments. Lactone intermediates accessed via this route provide a useful platform for elaboration, as demonstrated by the preparation of a variety of C-nucleosides and fluorinated pentoses. Finally, this work has facilitated expedient syntheses of pharmaceutically active compounds currently in clinical use.

  An improved process for the preparation of 2′-modified nucleosides and 2′-deoxy-nucleosides, such as, β-L-2′-deoxy-thymidine (LdT), is provided. In particular, the improved process is directed to the synthesis of a 2′-deoxynucleoside that may utilize different starting materials but that proceeds via a chloro-sugar intermediate or via a 2,2′-anhydro-1-furanosyl-nucleobase intermediate. Where an 2,2′-anhydro- 1 -furanosyl base intermediate is utilized, a reducing agent, such as Red-Al, and a sequestering agent, such as 15-crown-5 ether, that cause an intramolecular displacement reaction and formation of the desired nucleoside product in good yields are employed. An alternative process of the present invention utilizes a 2,2′-anhydro-1-furanosyl base intermediate without a sequestering agent to afford 2′-deoxynucleosides in good yields. The compounds made according to the present invention may be used as intermediates in the preparation of other nucleoside analogues, or may be used directly as antiviral and/or antineoplastic agents.

  提供了一种改进的2'-改性核苷和2'-脱氧核苷的制备工艺，例如，β-L-2'-脱氧胸苷（LdT）。特别是，改进的工艺针对的是2'-脱氧核苷的合成，该合成可能使用不同的起始材料，但都通过氯糖中间体或通过2,2'-脱水-1-呋喃糖核苷中间体进行。当使用2,2'-脱水-1-呋喃糖碱基中间体时，会采用还原剂（如Red-Al）和隔离剂（如15-冠-5醚），它们能引起分子内位移反应，并形成所需核苷产品的高收率。本发明的一种替代工艺使用2,2'-脱水-1-呋喃糖碱基中间体而不使用隔离剂，也能以高收率获得2'-脱氧核苷。根据本发明制成的化合物可以作为制备其他核苷类似物的中间体，或者可以直接用作抗病毒和/或抗肿瘤剂。

  本发明提供了一种改进的方法，用于制备2'-修饰核苷和2'-去氧核苷，例如β-L-2'-去氧胸腺嘧啶（LdT）。特别是，改进的方法针对合成一种2'-去氧核苷，该方法可以利用不同的起始材料，但是通过氯代糖中间体或2,2'无水-1-呋喃基-核碱中间体进行。当使用2,2'-无水-1-呋喃基碱中间体时，采用还原剂（如Red-Al）和隔离剂（如15-冠-5醚），引起分子内位移反应并形成所需的核苷产物，产率良好。本发明的另一种替代方法利用无隔离剂的2,2'-无水-1-呋喃基碱中间体，以获得良好的2'-去氧核苷收率。根据本发明制备的化合物可以用作制备其他核苷类似物的中间体，或者可以直接用作抗病毒和/或抗肿瘤剂。
