Whereas the synthesis of alpha-campholenic compounds starting from alpha-pi
nene has been well investigated, only few is known about beta-campholenic c
ompounds. We obtained compounds suitable as precursors for the functionaliz
ation of the side chain of the beta-isomer of the sandalwood flavour Brahma
nol(R). Now we report about the synthesis and the rearrangement of various
beta-campholenic epoxides to allylic alcohols or a bicyclic gamma-lactone a
nd the synthesis of cyclohexenones from beta-campholenic esters.
