Described is a process for preparing a genus of substituted 1-acetyl-3,3-dimethylcyclohexanes having the structure: STR1 wherein R1 or one or both of R2 and/or R3 is allyl or methallyl and the other of R1 or R2 and/or R3 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.

Described in a genus of substituted 1-acetyl-3,3-dimethylcyclohexanes having the structure: STR1 wherein R1 or one or both of R2 and/or R3 is methallyl and the other of R1 or R2 and/or R3 is hydrogen, a process for preparing same by means of reacting a methallyl halide with acetyl-3,3-dimethylcyclohexane using a phase transfer agent and in a two phase system according to the reaction: STR2 wherein X is chloro or bromo, processes for adding such 1-acetyl-3,3-dimethylcyclohexane derivatives to consumable materials whereby: (i) In foodstuffs and medicinal products, fatty, sweet, fruity, citrus, green and vegetable-like aromas and fatty, sweet, fruity, citrus, vegetable-like and waxy flavor characteristics are augmented or enhanced; (ii) In perfumes and perfumed articles, green, herbaceous, melony and fruity aromas with galbanum-like, ginger-like and citrusy nuances 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 mainstream and in the sidestream on smoking and, in addition, prior to smoking and flavor composition, perfume compositions and tobacco articles and foodstuffs and perfumed articles containing such 1-acetyl-3,3-dimethylcyclohexane derivatives.
