  A concise synthesis of 3′-α-fluoro-2′,3′-dideoxyguanosine (FddG) via 3′-α-selective fluorination of 8,2′-thioanhydronucleoside

  摘要：

  The antiviral nucleoside 3'-alpha-fluoro-2',3'-dideoxyguanosine (FddG) was synthesized via 3'-alpha-selective fluorination of 8,2'thioanhydronucleoside as the key step. Desulfurization of Y-alpha-fluoro-3'-deoxy-8,2'-thioanhydronucleoside could be achieved by the treatment with Raney Ni in toluene. This method provides a concise route to 3'-alpha-fluoro-2',3'-dideoxynucleosides that avoids the use of explosive and expensive SF4-related fluorinating reagents. (c) 2006 Elsevier Ltd.

  摘要：

  嘌呤核苷在3'-位（最好是α-位）被氟化后，可以通过氟化一种新的嘌呤核苷衍生物（1）来经济高效地生产，其中5'-位的羟基被保护以获得高产率的新嘌呤核苷衍生物（2）。衍生物（2）经过脱硫化、去保护R1，必要时保护、去保护或修饰核酸碱基部分，以获得所需的嘌呤核苷（3）。 其中每个符号的定义如规范中所述。

  Purine nucleosides which are fluorinated at the 3'-position (preferably the α-position), may be economically and efficiently produced by fluorinating a novel purine nucleoside derivative (1) in which the hydroxyl group at the 5'-position is protected to obtain a novel purine nucleoside derivative (2) in a high yield. The derivative (2) is subjected to desulfurization, deprotection of R1 and, as necessary protection, deprotection, or modification of nucleic acid base moiety, to obtain the desired purine nucleoside (3). wherein each symbol is as defined in the specification.
