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.
本发明涉及一种制备置换的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中的一个或两个是烯丙基或甲烯丙基,而另一个是氢。制备该物质的过程是通过使用碱底物将烯丙基或甲烯丙基卤化物与乙酰-3,3-二甲基环己烷反应:##STR2##其中R是烯丙基或甲烯丙基,X是氯或溴。当这种1-乙酰基-3,3-二甲基环己烷衍生物被添加到消费品中时:(i) 在食品和药品中,增强了菠萝、烯丙酸己酯类、牛膝草、木质、脂肪、甜味、果香、柑橘、绿色和蔬菜般的香气,以及玫瑰、紫罗兰、东方味、木质、脂肪、甜味、果香、柑橘、蔬菜味和蜡质风味特征;(ii) 在香水和带香物品中,赋予了带有菠萝、琥珀、牛膝草般的、姜味和柑橘味微妙差别的甜味、泥土味、动物味、绿色、草本、甜瓜和果香香气,以及烟草/动物味;(iii) 在烟草和烟草风味中,在吸烟时和吸烟前,增强了绿色、甜味、果香、花香和弗吉尼亚烟草般的风味和香气特征。
