The naturally occurring eudesmanolide farinosin () is now fully characterized for the first time despite its original isolation almost half a century ago. The early assumed relative stereochemistry and absolute configuration were confirmed by vibrational circular dichroism together with evaluation of the Hooft X-ray parameters. The molecular conformation is very similar in the gas stage and in the solid state. Chirality 28:415-419, 2016. © 2016 Wiley Periodicals, Inc.
天然存在的桉叶烷内酯farinosin（）尽管在近半个世纪前就已首次分离出来，但直到现在才得到全面表征。通过振动圆二色性以及对胡夫特X射线参数的评估，证实了早期假定的相对立体化学和绝对构型。其分子构象在气态和固态下非常相似。《手性》2016年第28卷，第415 - 419页。© 2016威利期刊公司。
