  Regioselective 1-N-Alkylation and Rearrangement of Adenosine Derivatives

  摘要：

  Several methods for the preparation of some N-6-substituted adenosines based on selective 1-N-alkylation with subsequent Dimroth rearrangement were developed. The proposed methods seem to be effective for the preparation of natural N-6-isopentenyl- and N-6-benzyladenosines, which are known to possess pronounced biological activities. Direct 1-N-alkylation of 2 ',3 ',5 '-tri-O-acetyladenosine and 3 ',5 '-di-O-acetyl-2 '-deoxyadenosine with alkyl halides in N,N-dimethylformamide (DMF) in the presence of BaCO3 and KI gave 1-N-substituted derivatives with quantitative yields, whereas 1-N-alkylation of adenosine was accompanied by significant O-alkylation. Moreover, the reaction of trimethylsilyl derivatives of N-6-acetyl-2 ',3 ',5 '-tri-O-acetyladenosine and N-6-acetyl-3 ',5 '-di-O-acetyl-2 '-deoxyadenosine with alkyl halides leads to the formation of the stable 1-N-substituted adenosines. Dimroth rearrangement of 1-N-substituted adenosines in aqueous ammonia yields pure N-6-substituted adenosines.

• Noncanonical RNA Nucleosides as Molecular Fossils of an Early Earth-Generation by Prebiotic Methylations and Carbamoylations

  prebiotic routes towards RNA. Contemporary RNA, however, is not only constructed from the four canonical nucleobases (A, C, G, and U), it also contains many chemically modified (noncanonical) bases. A still open question is whether these noncanonical bases were formed in parallel to the canonical bases (chemical origin) or later, when life demanded higher functional diversity (biological origin). Here

  RNA世界假说假设地球上的生命始于催化其自身形成的小RNA分子。对该假设至关重要的是，需要针对RNA的益生元途径。然而，当代RNA不仅由四个规范的核碱基（A，C，G和U）构建，而且还包含许多化学修饰的（非规范）碱基。一个尚待解决的问题是，当生命需要更高的功能多样性（生物起源）时，这些非规范碱基是否与规范碱基（化学起源）平行或更晚地形成。在这里，我们显示异氰酸酯与亚硝酸钠的组合建立了与地球早期条件相容的甲基化和氨基甲酰化反应性。这些反应导致仍然存在的甲基化和氨基酸修饰的核苷的形成。

  and convenient method for the synthesis of several pyrimidine and purine nucleosides by selective oxidation of thionucleosides with dimethyldioxirane is reported. Thioketo moieties in the C-4 position of the pyrimidine ring, and in the C-6, and C-8 positions of the purine ring are the domain of oxidative nucleophilic substitution. Thioketo moieties in the C-2 position of both purine and pyrimidine rings

  2′,3′,5′-tri-O-acetyl-nucleosides in water has been developed. Furthermore, a long-chain selective glycerol-3-phosphocholine diacylation is elucidated. These reactions are environmentally benign, rapid, high yielding, and the products are readily purified. Importantly, this reaction may indicate a prebiotically plausible reaction pathway for the selective acylation of key metabolites to facilitate their

• Solventless Protocol for Efficient Bis-<i>N</i>-Boc Protection of Adenosine, Cytidine, and Guanosine Derivatives
  作者：Siddharth A. Sikchi、Philip G. Hultin

  DOI：10.1021/jo060430t

  日期：2006.8.1

  A solvent-free reaction employing a simple low-energy ball mill apparatus converts the amino groups of adenosine, 2-deoxyadenosine, cytidine, 2-deoxycytidine, guanosine, and 2-deoxyguanosine as well as some of their ribosyl O-protected derivatives to the corresponding bis-N-Boc carbamates. In the case of guanosine compounds, the carbonyl group of the base moiety was also blocked as its O-Boc enol carbonate

  使用简单的低能球磨仪进行的无溶剂反应将腺苷，2-脱氧腺苷，胞嘧啶核苷，2-脱氧胞苷，鸟苷和2-脱氧鸟苷的氨基以及它们的一些核糖基O保护的衍生物转化为相应的bis- N -Boc氨基甲酸酯。在鸟苷化合物的情况下，该碱基部分的羰基也被封闭为其O- Boc烯醇碳酸酯。使用瞬态原位O硅烷化的这种方法的一种变体允许制备bis- N-Boc核苷，其中糖羟基不受保护。除鸟苷化合物外，球磨反应迅速，方便且产率很高。这种高效的方法使用适合进一步合成操作的碱稳定且酸不稳定的基团保护这些核苷的氨基。
