Described is a process for the preparation of compositions of matter containing unsaturated lactones defined according to the generic structure:
wherein R represents C6 alkyl or alkenyl; and X represents C2, C4 or C6 alkylene or alkenylene; with the provisos that R is C6 alkyl when X is alkenylene and R is C6 alkenyl when X is alkylene by means of the sequential steps of (i) fermentation of castor oil or ricinoleic acid using a microorganism selected from the group consisting of: Candida petrophilum, ATCC 20226; Candida oleophila, ATCC 20177; Candida sp., ATCC 20504; and Candida sake, ATCC 28137 whereby gamma hydroxydecanoic acid and a mixture of other acids defined according to the generic structure:
is formed wherein Y represents an oxo-saturated, oxo-unsaturated or di-unsaturated C9, C11 or C13 moiety according to the reaction:
(ii) lactonization of the resulting gamma hydroxydecanoic acid by means of simultaneous acidification and heating according to the reaction:
and (iii) lactonization (via distillation) of one or more of the resulting acids defined according to the structure:
to form one or more lactones defined according to the generic structure:
according to the reaction:
wherein the sum of the number of carbon atoms in the X moiety and in the R moiety is equal to the number of carbon atoms in the Y moiety minus 1.
Also described are the products produced according to such process as well as their organoleptic utilities for augmenting or enhancing the aroma or taste of consumable materials selected from the group consisting of perfume compositions, colognes, perfumed articles, perfumed polymers, foodstuffs, chewing gums, medicinal products, toothpastes, chewing tobaccos and smoking tobaccos.
本发明描述了一种制备含有根据通用结构定义的不饱和内酯的物质组合物的工艺:
其中R代表C6烷基或烯基;X代表C2、C4或C6亚烷基或烯基;但条件是当X为烯基时,R为C6烷基;当X为亚烷基时,R为C6烯基,制备方法为(i)使用选自以下组成的组的微生物发酵蓖麻油或蓖麻油酸,(ii)使用选自以下组成的组的微生物发酵蓖麻油或蓖麻油酸,(iii)使用选自以下组成的组的微生物发酵蓖麻油或蓖麻油酸:Candida petrophilum,ATCC 20226;Candida oleophila,ATCC 20177;Candida sp.,ATCC 20504;和 Candida sake,ATCC 28137:
其中 Y 代表氧饱和、氧不饱和或二不饱和 C9、C11 或 C13 分子:
(ii) 根据反应,通过同时酸化和加热,对生成的γ-羟基癸酸进行内酯化:
和 (iii) (通过蒸馏)对所得到的一种或多种根据结构定义的酸进行内酯化:
形成一种或多种按通用结构定义的内酯:
根据反应
其中 X 分子和 R 分子的碳原子数之和等于 Y 分子的碳原子数减去 1。
此外,还描述了根据这种工艺生产的产品及其感官效用,这些产品用于增加或提高从香水组合物、古龙水、香水制品、香味聚合物、食品、口香糖、医药产品、牙膏、咀嚼烟草和吸烟烟草组成的组中选出的消耗材料的香气或味道。

Described is a bioprocess for the high-yield production of food flavor-acceptable jasmonic acid and methyl jasmonate, as well as a novel jasmonic acid isomer produced thereby and organoleptic uses thereof. The process yields at least 5% of the "cis" isomer defined according the structure:
(wherein R is hydrogen or methyl) or at least 5% of the "cis" isomer defined according to the structure:
(wherein R is hydrogen or methyl). Compositions containing at least 98% of the isomer having the structure:
with an optical rotation (α20D) of +58° are novel. Compositions containing at least 98% of the isomer having the structure:
with an optical rotation (α20D) of +58° are also novel. The process of our invention comprises the cultivation under aerobic condition of one or more specific strain of Diplodia gossypina in a nutrient medium followed either by (1) isolation of the jasmonic acid product or (2) esterification of the jasmonic acid to form methyl jasmonate followed by the isolation of the methyl jasmonate and novel products produced by such process.
