Despite the central role of germacrene A in sesquiterpene biosynthesis and its widespread occurrence in nature, its complete NMR characterization is still pending. This problem was solved through enzymatic preparation of germacrene A isotopomers that allowed for a full signal assignment to all three conformers. The obtained materials gave insights into the stereochemical course of the Cope rearrangement to β-elemene and uncovered the Cope rearrangement as a new EI-MS fragmentation reaction.

通过同位素标记实验解决Germacrene A的化学反应
尽管胚ac烯A在倍半萜生物合成中起着核心作用,并且在自然界中广泛存在,但其完整的NMR表征仍在进行中。该问题通过酶法制备的ac草烯A异构体得以解决,该异构体可将信号完全分配给所有三个构象异构体。获得的材料提供了Cope重排为β-榄香烯的立体化学过程的见解,并揭示了Cope重排作为一种新的EI-MS片段化反应。
