标题:一种乙酸邻叔丁基环己酯香料的合成方法
摘要:本发明公开了一种乙酸邻叔丁基环己酯香料的合成方法,先后将石油醚和苯酚加入到三口玻璃烧瓶中,再加入二氧化钛负载磷钨酸催化剂,在10~‑15oc下,滴加叔丁醇,将玻璃烧瓶产生的邻叔丁基苯酚和对叔丁基苯酚的混合反应液分层,油层先碱后水洗在钯碳催化剂作用下进行加氢反应,收集的邻叔丁基环己醇加入醋酸酐和对甲苯磺酸,回收醋酸后,油层经碱洗,水洗和蒸发后得乙酸邻叔丁基环己酯.本发明方法原料易得,产品得率高,最终产品含量达98.5%以上,产品中顺式异构体含量达到85%以上,从而使得最终产品的香气纯正柔和,符合香精香料调香的要求.

标题 :Novel hydroxylated enantiomers of (-) 3a,6,6,9a-tetramethylperhydronaphtho[2,1-b]furan as perfuming agents derived from a fungal fermentation process.

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.

标题 :Alpha alkylation of aldehyde with a polycyclic olefin
发明人：QUINTAINE JULIE; MACMILLAN DAVID W C
权利人:FIRMENICH & CIE
摘要:The present invention relates to the field of organic synthesis and more specifically to the alpha alkylation of an aldehyde with a polycyclic olefin followed by a ring opening step in order to provide compound of formula (I) in the form of any one of its stereoisomers or a mixture thereof and wherein R represents a hydrogen atom or C 1-8 linear alkyl group; R 1 , R 2 , R 3 and R 4 represent, when taken separately, independently of each other, a hydrogen atom or a C 1-2 linear alkyl group or a C 3-4 linear or branched alkyl group; or R 2 and R 3 , when taken together, represent a C 4-10 linear, branched or cyclic alkanediyl group and n is 1 or 2.

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.
