Described is a process for preparing a genus of substituted 1-acetyl-3,3-dimethylcyclohexanes having the structure: ##STR1## wherein R.sub.1 or one or both of R.sub.2 and/or R.sub.3 is allyl or methallyl and the other of R.sub.1 or R.sub.2 and/or R.sub.3 is hydrogen, a process for preparing same by means of reacting an allyl or a methallyl halide with acetyl-3,3-dimethyl-cyclohexane using a base according to the reaction: ##STR2## wherein R is allyl or methallyl and wherein X is chloro or bromo. When such 1-acetyl-3,3-dimethylcyclohexane derivatives are added to consumable materials: (i) In foodstuffs and medicinal products, pineapple, allyl caproate-like, galbanum, woody, fatty, sweet, fruity, citrus, green and vegetable-like aromas and rosey, ionone, Oriental-like, woody, fatty, sweet, fruity, citrus, vegetable-like and waxy flavor characteristics are augmented or enhanced; (ii) In perfumes and perfumed articles, sweet, earthy, animal, green, herbaceous, melony and fruity aromas with pineapple, ambery, galbanum-like, ginger-like and citrusy nuances and tobacco/animal notes are imparted, augmented and/or enhanced; and (iii) In tobaccos and tobacco flavors, green, sweet, fruity, floral and Virginia tobacco-like flavor and aroma nuances are augmented and/or enhanced in the main stream and in the side stream on smoking and, in addition, prior to smoking.
本文描述了一种制备取代的1-乙酰基-3,3-二甲基环己烷属的过程,其结构为:##STR1## 其中R.sub.1或R.sub.2和/或R.sub.3中的一个或两个是丙烯基或甲基丙烯基,而R.sub.1或R.sub.2和/或R.sub.3中的另一个是氢。通过使用碱将丙烯基或甲基丙烯基卤化物与乙酰-3,3-二甲基环己烷反应,制备同样的化合物,反应如下:##STR2## 其中R为丙烯基或甲基丙烯基,X为氯或溴。当这种1-乙酰基-3,3-二甲基环己烷衍生物添加到可消费物料中时:(i) 在食品和医药制品中,增强了菠萝、丙烯酸己酯样、大香脂、木质、脂肪、甜味、果香、柑橘、绿色和蔬菜香味以及玫瑰、紫罗兰、东方样、木质、脂肪、甜味、果香、柑橘、蔬菜和蜡味的特征;(ii) 在香水和香氛制品中,赋予了甜味、泥土味、动物味、绿色、草本、蜜瓜和果香,以及菠萝、琥珀、大香脂样、姜味和柑橘味的细微差别和烟草/动物的气味;(iii) 在烟草和烟草香味中,在吸烟的主流和侧流以及吸烟前,增强了绿色、甜味、果香、花香和弗吉尼亚烟草样的味道和香味细微差别。
