  7-Functionalized 7-Deazapurine Ribonucleosides Related to 2-Aminoadenosine, Guanosine, and Xanthosine:  Glycosylation of Pyrrolo[2,3-d]pyrimidines with 1-O-Acetyl-2,3,5-tri-O-benzoyl-d-ribofuranose

  摘要：

  The Silyl-Hilbert-Johnson reaction as well as the nucleobase-anion glycosylation of a series of 7-deazapurines has been investigated, and the 7-functionalized 7-deazapurine ribonucleosides were prepared. Glycosylation of the 7-halogenated 6-chloro-2-pivaloylamino-7-deazapurines 9b-d with 1-O-acetyl2,3,5-tri-O-benzOyl-D-ribofuranose (5) gave the beta-D-nucleosides 11b-d (73-75% yield), which were transformed to a number of novel 7-halogenated 7-deazapurine ribonucleosides (2b-d, 3b-d, and 4b-d) related to guanosine, 2-aminoadenosine, and xanthosine. 7-Alkynyl derivatives (2e-i, 3e-h, or 4g) have been prepared from the corresponding 7-iodonucleosides 2d, 3d, or 4d employing the palladium-catalyzed Sonogashira cross-coupling reaction. The 7-halogenated 2-amino-7-deazapurine ribonucleosides with a reactive 6-chloro substituent (18b-d) were synthesized in an alternative way using nucleobase-anion glycosylation performed on the 7-halogenated 2-arnino-6-chloro-7-deazapurines 13b-d with 5-0-[(1,1dimethylethyl)dimethylsilyl]-2,3-O-(1-methylethylidene)-alpha-D-ribofuranosyl chloride (17). Compounds 18b-d have been converted to the nucleosides 19b-d carrying reactive substituents in the pyrimidine moiety. Conformational analysis of selected nucleosides on the basis of proton coupling constants and using the program PSEUROT showed that these ribonucleosides exist in a preferred S conformation in solution.

  The synthesis of 2′-β-C-methyl-neplanocin derivatives is described. The key intermediate cyclopentenyl alcohol 12 is prepared from sugar 5 in 12 steps. Coupling of 12 with appropriately protected purine, 7-deaza pyrimidine, uracil and pyrimidine bases via the Mitsunobu reaction followed by deprotection afforded the target cyclopentenyl nucleosides (18–23, 27). The synthesized compounds were evaluated

  描述了2'-β- C-甲基-neplanocin衍生物的合成。关键中间体环戊烯基醇12由糖5以12个步骤制备。的耦合12与适当保护的嘌呤，通过Mitsunobu反应7-脱氮嘧啶，尿嘧啶和嘧啶碱基，接着脱保护得到目标环戊烯基核苷（18 - 23，27）。合成的化合物被评估为体外丙型肝炎病毒（HCV）的潜在抑制剂。不幸的是，它们都没有显示出低于EC 50 100μM的抗HCV活性。
