Abstract
A novel bioactive monotetrahydrofuran acetogenin named tonkinecin (1) and two known compounds, uvariamicins I and II, have been isolated from the roots of Uvaria tonkinesis. The structure of 1 was elucidated using spectral methods and its absolute stereochemistry established by 1H-NMR experiments utilizing Mosher ester methodology.
摘要
从东京紫玉盘（Uvaria tonkinesis）的根中分离出一种名为东京紫玉盘素（1）的新型生物活性单四氢呋喃类番荔枝内酯以及两种已知化合物——紫玉盘菌素I和II。通过光谱方法阐明了1的结构，并利用莫舍尔酯法通过1H-NMR实验确定了其绝对立体化学结构。
