In connection with structure-activityrelationship studies, analogues of campholenal ((+)-4b), an important building block for sandalwood-like odorants, were prepared. The five-membered-ring analogues 4 were obtained by epoxidation of the corresponding α-pinene derivatives 2, followed by catalytic ZnBr2 isomerisation (Scheme 2). The six-membered-ring skeleton was obtained by ozonolysis of α-campholenyl
