The structure of the sesquiterpene ketone buddledin C isolated from Pulicaria prostrata (Gilib.) Aschers., was confirmed by XSA. The stereochemistry of its epoxide, which was formed selectively by treating it with hydrogen peroxide in alkaline solution, was proposed based on quantum-chemical and molecular-mechanical calculations.
用 XSA 法证实了从 Pulicaria prostrata (Gilib.) Aschers.中分离出的倍半萜酮类植物菩提素 C 的结构。在量子化学和分子力学计算的基础上,提出了其环氧化物的立体化学结构,该环氧化物是在碱性溶液中用过氧化氢有选择性地处理后形成的。
