corresponding 1-norbornylamines 2 and 13 and the N-ethyl derivatives 1, 6, 11, and 12 were obtained by basic hydrolysis or reduction with LiAlH4, respectively, of the amides 4, 5, 9, and 10. The antiviral activity of the hydrochlorides of some of the obtained 1-norbornylamines was evaluated against influenza A, herpes simplex 2, and African swine fever virus. Particularly noticeable is the activity of the
(+/-)樟脑(7)与三氟甲磺酸酐(Tf2O)的反应生成桥头三氟甲磺酸酯8。通过用三氟甲磺酸(TfOH)处理,实现了8至3的Nametkin重排。桥头三氟甲磺酸酯3和8在乙腈中的溶剂分解得到N-乙酰基-1-降冰片胺4和9。Pd(0)催化4和9的氢化得到酰胺5和10。相应的1-降冰片胺2和1分别通过碱性水解或用LiAlH4还原酰胺4、5、9和10分别制得13和N-乙基衍生物1、6、11和12。某些所得盐酸盐的抗病毒活性对1-降冰片胺进行了抗A型流感,单纯疱疹2型和非洲猪瘟病毒的评估。
