  Synthesis of 3′-deoxy-3′-C-methyl-β-d-ribonucleoside analogs

  摘要：

  3'-Deoxy-3'-C-methyl-beta-D-ribonucleoside analogs bearing the five canonical bases of nucleic acids have been synthesized. All these derivatives were prepared by glycosylation of the corresponding heterocyclic bases with a suitable peracylated 3-C-methyl sugar precursor. The synthesis of the 3-C-methyl sugar precursor is described following a new stereoselective synthetic pathway. (C) 2007 Elsevier Ltd. All rights reserved.

  Revisited 3′-Deoxy-3′-C-Methyl-β-D-Ribonucleoside Series

  摘要：

  The synthesis of some 3'-deoxy-3'-C-methylnucleoside analogues bearing naturally occuring nucleic acid bases was achieved from the preparation of a suitable peracylated 3-deoxy-3-C-methyl sugar using a stereoselective pathway. In addition, examples of chemical modifications at the 2' position are presented.

  2',3'-Dideoxy-3'-C-methyl nucleosides bearing the five naturally occurring nucleic acid bases were synthesized. Additionally, the 3'-deoxy-3'-C-methyl nucleoside analogues bearing 5-aminoimidazole-4-carboxamide as well as 1,2,4-triazole-3-carboxamide moieties were prepared. The synthesis of the corresponding 2',3'-dideoxy-3'-C-methyl triazole derivative was also accomplished. The dideoxynucleoside

  合成带有五个天然存在的核酸碱基的2'，3'-二脱氧-3'-C-甲基核苷。另外，制备了带有5-氨基咪唑-4-羧酰胺以及1,2,4-三唑-3-羧酰胺部分的3'-脱氧-3'-C-甲基核苷类似物。还完成了相应的2'，3'-二脱氧-3'-C-甲基三唑衍生物的合成。通过从它们的3'-脱氧-3'-C-甲基母体核糖核苷进行自由基脱氧制备二脱氧核苷衍生物。当在细胞培养实验中评估其抗病毒活性时，这些化合物均未显示任何显着的抗病毒活性。
