  Synthesis of 8-alkyladenosines and related nucleosides is described. Treatment of 5'-O-acetyl-2', 3'-O-isopropylidene-8-methylsulfonyladenosine with ethyl sodioacetoacetate gave the 8-ethoxy-carbonylmethyl derivative (1). Hydrolytic decarboxylation of 1 followed by deacetonation afforded 8-methyladenosine (2) in high yield. Alkylation of 1 with methyl or ethyl iodide followed by hydrolytic decarboxylation afforded 8-ethyl- and 8-propyladenosines, respectively. Attempts at dimethylation of the 8-methylene group of 1 resulted in the formation of the N6-dimethyladenosine derivative. Selective dimethylation of the amino groups of 2'-deoxyadenosine and 2'-deoxycytidine has been accomplished by using a combination of methyl iodide and sodium hydride without methylation of the sugar hydroxyl groups of these nucleosides. 8, 2'-Anhydro-9-β-D-arabinofuranosyl-8-hydroxymethyladenine was prepared from a 8-cyanoadenosine derivative by the procedure involving anhydro-bond formation by base treatment of 8-hydroxymethyl-2'-Otosyladenosine. The circular dichroism spectral characteristics of 8-alkyladenosines are discussed.

  介绍了 8-烷基腺苷和相关核苷的合成。将 5'-O-乙酰基-2'，3'-O-异亚丙基-8-甲磺酰基腺苷与钠基乙酰乙酸乙酯进行处理，可得到 8-乙氧羰基甲基衍生物（1）。对 1 进行水解脱羧，然后进行脱乙酰基反应，可得到高产率的 8-甲基腺苷（2）。用甲基或乙基碘对 1 进行烷基化，然后进行水解脱羧，可分别得到 8-乙基和 8-丙基腺苷。尝试对 1 的 8-亚甲基进行二甲基化会生成 N6-二甲基腺苷衍生物。使用甲基碘和氢化钠的组合，可以选择性地对 2'-脱氧腺苷和 2'-脱氧胞苷的氨基进行二甲基化，而不会对这些核苷的糖羟基进行甲基化。8, 2'-脱水-9-β-D-阿拉伯呋喃糖基-8-羟甲基腺嘌呤是由 8-氰基腺苷衍生物通过碱处理 8-羟甲基-2'-对甲苯磺酰基腺苷形成氢键的过程制备的。讨论了 8-烷基腺苷的圆二色性光谱特征。
