摘要:An economical process for producing (2- and/or 1-)cyclohexenyl methyl ketones which are intermediates for the synthesis of alpha- or beta-damascone. In the presence of a catalyst, a 3-cyclohexenyl methyl ketone represented by the following formula (1a):wherein, R1, R2 and R3 each independently represents a hydrogen atom or a methyl group and at least two of R1, R2 and R3 are methyl groups, is isomerized.

摘要:An active biocatalyst for converting alpha-pinene epoxide to terpenic aldehydes useful in perfumery, e.g. formula (I), is produced by growing a microorganism, preferably Pseudomonas fluorescens NCIB 40043, to late log phase in a medium containing carbohydrate (e.g. glucose) as the carbon source, and adding alpha-pinene. The resulting culture comprises active biocatalyst which is brought into contact with alpha-pinene epoxide for aldehyde synthesis.
