g. opening of epoxides), to transannular reactions and/or to unidentified mixtures. Sarcophine (7), the principal cembrane tested, was found to afford either all types of possible epoxide opening products (11–22), or, by a transannular reaction, when treated with SnCl4, two tetrahydrooxepine derivatives (23 and 24). The structure determination of the various derivatives of sarcophine was based mainly
在不同的实验条件下,用不同的酸处理了几种西em二萜。发现所有测试的化合物都是酸敏感的,从而导致局部化学转化(例如,环氧化物的开放),环空反应和/或未知混合物。发现主要测试过的石蜡石蜡(7)可以提供所有类型的可能的环氧开放产物(11-22),或者通过环过环反应,当用SnCl 4处理时,可以提供两种四氢氧杂环丁烷衍生物(23和24)。鼠藤碱的各种衍生物的结构确定主要基于1 H和13 C-NMR光谱,还基于几种化学转化。
