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.

摘要:(−) 3a,6,6,9a-tetramethylperhydronaphtho[2,1-b]furan (ambrox) is a strong aromatic compound used widely in a variety of perfumery applications and is highly prized for its musky odor. We report novel polar metabolites of (−)3a,6,6,9a-tetramethylperhydronaphtho[2,1-b]furan prepared by a novel process of microbial fermentation using a fungi, Fusarium lini , of unique structures that would be difficult to predict opening up the possibilities of their chemical synthesis. The polar metabolites discovered have stronger aromatic characteristics and offer a new highly prized odiferous characteristic quite different from that of the parent compound and thus can be used in the preparation of perfumes, odor-masking and other odor-management applications.
