The successful application of the nickel catalyzed, intramolecular [4+4] cycloaddition of bisdienes to the preparation of both the AB and BC ring systems of the taxane diterpenes is described. This cycloaddition methodology provides the basis for a general and efficient route to angularly alkyl-subs
The addition of an acetyl radical on caryophyllene leads to formation of the four isomeric ketones 5-8 involving a novel rearrangement of the caryophyllene skeleton. The acid catalyzed rearrangement of caryophyllene 1 has been studied in detail'. The final re-\_ action products are clovene 2, caryo
## Abstract On treatment with phosphorus oxychloride, the decalin derivative 6 underwent rearrangement yielding principally the perhydroazulene derivative 8. Similar rearrangement was also observed on dehydration of the decalin derivative 9.
