A new approach to the preparation of N,N′-unsymmetrically substituted 9-aminobispidines through aminal bridge removal reaction has been developed, the principal feature of which is the ability to selectively functionalize all three nitrogen atoms. The intermediates of 1,3-diazaadamantane’s aminal bridge removal reaction are characterized, and the mechanism of this reaction is proposed based on the
开发了一种通过缩醛桥去除反应制备 N , N ′-不对称取代的 9-氨基双吡啶的新方法,其主要特征是能够选择性地官能化所有三个氮原子。表征了1,3-二氮杂金刚烷脱氨桥反应的中间体,并在分析其结构的基础上提出了该反应的机理。以前未知的饱和杂环的代表1,5,9-triazatricyclo[5.3.1.0 3,8]获得十一烷系统并对其进行结构表征。因此,首次有可能获得在氮原子上含有乙酰基、Boc 和苄基的 3,7,9-三取代双吡啶,这些基团可以独立去除(正交保护基)。

The antiviral activity of several diaza-adamantanes containing monoterpenoid moieties against a rimantadine-resistant strain of the influenza A/Puerto Rico/8/34 (H1N1) virus was studied. Hetero-adamantanes containing monoterpene moieties at the aminal position of the heterocycle were found to exhibit lower activity compared to compounds with a diaza-adamantane fragment and a monoterpene moiety linked via an amino group at the 6-position of the hetero-adamantane ring. The highest selectivity index (a ratio of the 50% cytotoxic concentration to the 50% inhibitory concentration) out of 30 was observed for compound 8d, which contains a citronella] monoterpenoid moiety. Diaza-adamantane 8d was superior to its adamantane-containing analog 5 both in its anti-influenza activity and selectivity. Furthermore, 8d has more balanced physicochemical properties than 5, making the former a more promising drug candidate. Modelling these compounds against an influenza virus M2 ion channel predicted plausible binding modes to both the wild-type and the mutant (S31N). (C) 2017 Elsevier Ltd. All rights reserved.
