The boron trifluoride catalyzed rearrangement of 7,11-epoxygermacrone (1) provided the new diketone in high yield. This transformation represents the first biomimetic chemical conversion of a germacrane into a humulane skeleton. The cation J\_ is generally considered as the biogenetic precursor of s
