Topics: Chemistry and Pharmacology

Notes: Summary. Whereas the synthesis of α-campholenic compounds starting from α-pinene has been well investigated, only few is known about β-campholenic compounds. We obtained compounds suitable as precursors for the functionalization of the side chain of the β-isomer of the sandalwood flavour Brahmanol®. Now we report about the synthesis and the rearrangement of various β-campholenic epoxides to allylic alcohols or a bicyclic γ-lactone and the synthesis of cyclohexenones from β-campholenic esters.

Topics: Chemistry and Pharmacology

Notes: Synthesis, Structure and Reactions of α-Campholenic EpoxidesThe epoxidation of α-campholenic compounds 3, 4 is described, besides the rearrangement of the epoxides 5 and 6 into the hydroxy-β-campholenic system 7, 8, the reduction to the tertiary alcohols 11a, 12a, the alkylation reaction to 11b and 12b and the conversion of 7 into the diketone 10 are reported. The stereochemistry and the odour of the new compounds are also described.
