摘要:A compound of general formula (I) with or without the double bond illustrated by the dotted line. In formula (I), X is a CHO, CH2OH, CH2OC(O)R or CH(OR)2 group, and R represents a linear or branched C1-C5 alkyl or alkenyl chain. The synthesis method for the compound, and especially the 6,8-dimethyl-non-7-enal (1) prepared by the hydroformylation of the 5,7-dimethyl-octa-1,6-diene is also disclosed, as well as compositions containing the compounds of formula (I). Due to the odorant properties thereof, the compounds are highly useful in perfumery, especially for cosmetic products and household products.

标题:Microbial biocatalyst for production of terpenic aldehydes
发明人：DAVIS KAREN JOHANNA; BEST DAVID JOHN; BURFIELD ANTHONY GRAHAM; TAYLOR FRANK; TALBOT JANE STELLA
权利人:NOVALAL LTD
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.
