The invention is concerned with odorant compositions which contain macrocycles, namely 15- to 17-membered compounds of the formula:
wherein the dotted line signifies an optional additional bond, X and Y stand for methylene or C2-12-polymethylene, optionally substituted with an additional methyl group, and A signifies hydrogen or methyl in the case of the unsaturated compounds and methyl in the case of the saturated compounds, with the proviso that the unsaturated compounds are present to more than 80% in the cis form when A signifies hydrogen and are present to more than 50% in the cis form when A signifies methyl, with the exception of Z-oxacyclopentadec-6-en-2-one (15-membered ring), Z-oxacycloheptadec-8-en-2-one (17-membered ring), and Z-oxacycloheptadec-11-en-2-one (17-membered ring), a process for the manufacture of the compounds of formula I and the use of the compounds of formula I as odorants.
本发明涉及含有大环化合物的气味剂组合物,即15至17成员的化合物,其化学式为:其中虚线表示可选的额外键,X和Y代表亚甲基或C2-12-聚亚甲基,可选地被额外的甲基基团取代,A表示在不饱和化合物中为氢或甲基,在饱和化合物中为甲基,但不饱和化合物中当A表示氢时以顺式形式存在的比例超过80%,当A表示甲基时以顺式形式存在的比例超过50%,除了Z-氧杂环戊十五烯-2-酮(15成员环)、Z-氧杂环庚十七烯-2-酮(17成员环)和Z-氧杂环庚十七烯-2-酮(17成员环)之外,还涉及制备式I化合物的方法以及将式I化合物用作气味剂的用途。
