The method is operationally simple (i.e., one-pot), scalable and fast at ambient temperature.
专利号:WO-2018192923-A1 优先权日:2017-04-18 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.
专利号:WO-8911536-A1 优先权日:1988-05-27 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.
