  Pd−Xantphos-Catalyzed Direct Arylation of Nucleosides

  摘要：

  Direct arylation of the exocyclic amino groups of nucleosides represents a simple approach to N-aryl nucleoside derivatives. To date, one limitation has been that only electron-deficient aryl bromides and triflates possessed adequate reactivity for efficient, direct N-arylation of nucleosides. We demonstrate herein that Pd-Xantphos catalytic systems lead to successful N-arylation of suitably protected 2'-deoxyadenosine and 2'-deoxyguanosine with a wide range of aryl bromides.

• Synthesis of 6-substituted 2′-deoxyguanosine derivatives using trifluoroacetic anhydride in pyridine
  作者：Fathi Reza、Goswami Bhaswati、Kung Pei-Pei、Barbara L. Gaffney、Roger A. Jones

  DOI：10.1016/s0040-4039(00)94543-x

  日期：1990.1

  Trifluoroacetic anhydride at 0° C reacts with a pyridine suspension of deoxyguanosine to generate a polar intermediate, presumably the corresponding 6-pyridyl derivative. The reaction is complete in less than 15 minutes, and is not accompanied by degradation. From this intermediate a variety of 6-substituted deoxyguanosine derivatives can be obtained, some in excellent yields.

  0℃下的三氟乙酸酐与脱氧鸟苷的吡啶悬浮液反应，生成极性中间体，可能是相应的6-吡啶基衍生物。反应在不到15分钟的时间内完成，并且没有降解。从该中间体可以得到多种6-取代的脱氧鸟苷衍生物，其中一些具有优异的收率。

  A one-pot synthesis of ethers derived from inosine, guanosine, 2'-deoxyguanosine, and pyrimidinones is described Exposure of the heterocycle to 1H-benzotriazol-1-yloxy-tris(dimethylamino)phosphonium hexafluorophosphate (BOP) and Cs2CO3 produces a reactive intermediate, which is converted to the desired ether by subsequent addition of an appropriate alcohol or phenol and Cs2CO3. Although rapid formation of HMPA from BOP can occur in the presence of an alcohol and base, as demonstrated by the reaction with methanol, under appropriate conditions these heteroaryl ethers can be efficiently synthesized

  [GRAPHICS]The 3',5'-bis-O-TBDMS derivative of 2'-deoxyguanosine can be converted to its O-6-alkyl and O-6-aryl ethers as well as to N-6-substituted diaminopurine nucleosides in two simple steps. Also described is a novel, nonaqueous, one-step O-6-desulfonylation method that leads to deprotection of the carbonyl moiety of 2'-deoxyguanosine.
• Direct Synthesis of 8-Fluoro Purine Nucleosides via Metalation−Fluorination
  作者：Arun K. Ghosh、Pallavi Lagisetty、Barbara Zajc

  DOI：10.1021/jo071121l

  日期：2007.10.1

  A straightforward access to protected 8-fluoro nucleosides via metal ation - electrophilic fluorination under heterogeneous reaction conditions is reported. This is the first synthesis of 8-fluoro-2(')-deoxyribonucleoside derivatives. Phenylsulfonyl substituted nucleosides are accompanying byproducts, possibly indicating a competing radical process. Higher yields of 8-fluoro derivatives were obtained with 2(')-deoxyribonucleosides, as compared to ribonucleosides. Deprotection of the hydroxyl groups leading to 8-fluoro-2(')deoxyadenosine using TASF in methylene chloride demonstrates the compatibility of desilylation with 8-fluoro substituted nucleosides. NMR data indicate a syn conformation of the 8-fluoro derivatives.
