    摘要:
    用沸腾的 2 N 盐酸处理 48 小时后,N6-甲基-8-氧代腺嘌呤核苷(1)、1-甲基-8-氧代腺嘌呤核苷(5)和 7-甲基-8-氧代腺嘌呤核苷(8)发生糖苷水解,但速度比相应的 8-未取代化合物慢得多,生成的缩醛(2、6 和 9)的产率为 45%-63%。在这些条件下,N6-甲基-8-氧代腺嘌呤(2)重新排列为 9-甲基-8-氧代腺嘌呤(3)(收率 8%),这可能是通过咪唑环的裂变和再封闭实现的。3- 甲基-8-羟基腺嘌呤(7)也发生了明显的甲基迁移,在类似条件下,用盐酸处理后可得到 1-甲基-8-氧代腺嘌呤(6),产率为 9%。

    7-Alkoxy-3-alkyladenine perchlorates (9) were prepared from 3-alkyladenines (4) by N-oxidation followed by alkylation with alkyl halides in N, N-dimethylacetamide. The 7-methoxy derivatives 9d, g, j thus obtained afforded 3-methyl-8-hydroxyadenine (7a), 3-ethyl-8-hydroxyadenine (7b), and 3-benzyl-8-hydroxyadenine (7c) in 74%, 72%, and 39% yields, respectively, on treatment with boiling 0.1 N aqueous sodium hydroxide, whereas treatment of 9d, g, j with sodium methoxide in methanol at room temperature afforded 3-alkyl-8-methoxyadenines (10m, p, q) in 91%-98% yields. Similar treatment of 9d with sodium ethoxide in ethanol afforded 8-ethoxy-3-methyladenine (10n) in 89% yield. Compounds 10m, q were alternatively prepared from 9d, j in 77% and 84% yields, respectively, by treatment with 0.1 N aqueous sodium hydroxide in the presence of methanol. This method was suitable for the synthesis of the 8-benzyloxy compound 10o : it was obtained in 60% yield by treating 7-benzyloxy-3-methyladenine perchlorate (9f) with a mixture of aqueous sodium hydroxide and benzyl alcohol. Compounds 7 were alternatively prepared from 9 through 10. For example, 7c was obtained in 84% overall yield by treatment of 9j with sodium methoxide, followed by hydrolysis of the resulting 10q with boiling 1 N hydrochloric acid.On the other hand, methylation of 3-methyladenine 7-oxide (8a) with dimethyl sulfate in 0.1 N aqueous sodium hydroxide in the absence or presence of added methanol afforded N6, 3-dimethyladenine 7-oxide (14) in 13% or 14% yield, together with 7a (4% yield) or 10m (11%).

    3-Alkyl-8-hydroxyadenines (5) have been shown to undergo regioselective methylation at the 7- or 9-position depending on the reaction conditions. Thus, treatment of 5a, c with dimetyl sulfate in aqueous NaOH provided 3-alkyl-7-methyl-8-oxoadenines (6b, h) in 48-60% yields, together with 3-alkyl-8-methoxyadenines 4d, h), whereas treatment of 5a-c with MeI in AcNMe2 at 40°C for 48h and subsequent anion exchange afforded 3-alkyl-9-methyl-8-oxoadenine hydrochlorides (7d, g, h·HCl) in 50-59% yieds. However, the reactions of 5a, c with EtI or PhCH2Br took place slowly, giving complex mixtures of products.Compounds 6d, h were alternatively prepared in 51% and 31% yields, respectively, together with 3-alkyl-7, 9-dimethyl-8-oxoadenine hydrochlorides (11d, h·HCl), by treatment of 3-alkyl-8-methoxyadenines (4d, h) with MeI in AcNMe2 at room temperature for 6 h, followed by hydrolysis with boiling aqueous HCl. This method was applicable to ethylation with EtI, and 7-ethyl-3-methyl-8-oxoadenine (6e) was obtained in 70% yield from 8-ethoxy-3-methyladenine (4e). Compound 11h was shown to be obtainable through futher methylation of 6h. Thus, 11d, h were prepared in good yields by treatment of 6d, h with MeI in AcNMe2.Compounds 7, to which zwitterionic structures were assigned, were stable in 0.1 N aqueous NaOH at room temperature, whereas 11d, h were no longer stable under such conditions.
