    摘要: A process of preparation of cis-2-acetyl-1,2,3,4,5,6,7,8-octahydro-1,2,8,8-tetramethylnaphthalene (“β-Georgywood”) from cis-1-[1,2-dimethyl-4(4-methyl-pent-3-enyl)-cyclohex-3-enyl]-ethanone (“Ψ-Georgywood”), comprising the reaction of Ψ-Georgywood with more than one molar equivalent of a Lewis acid. The method allows the preparation of isomeric mixtures that contain a much higher proportion of the olfactorily-desirable β-Georgywood than was previously possible.
