Description
La présente invention a pour objet une composition aromatisante, pour renforcer, améliorer ou modifier les propriétés organoleptiques du tabac.
Il est bien connu que le tabac utilisé pour la fabrication des cigarettes est essentiellement composé d'un mélange de différents types de tabacs qui donnent ainsi à la fumée l'arôme particulier que l'on désire obtenir. Ainsi, les cigarettes ordinaires contiennent des mélanges de tabacs de Virginie, Maryland ou du Kentucky et de tabacs orientaux ou turcs, les proportions respectives variant selon l'arôme particulier recherché. Il est également courant d'utiliser des substances aromatisantes et des humectants, afin d'améliorer l'arôme desdits mélanges de tabac.
Un des objets de la présente invention consiste en une composition destinée à renforcer, améliorer ou modifier les propriétés organoleptiques de la fumée de tabac (tabac naturel ou produit de remplacement du tabac, d'origine naturelle ou synthétique), ladite composition aromatisante étant caractérisée en ce qu'elle contient au moins un des composés appartenant au groupe des dérivés alicyliques suivants: a) 3,5,5-triméthyl-2,3-époxycyclohexa-1,4-dione c.n.
b) 4,4,Striméthylcyclohexa-2,5-diène-2-ol-1-one c.n.
c) 3,5,5-triméthylcyclohex-2-ène-2-ol-1-one J. Org. Chem.

A la suite de la désignation de chaque produit figure la référence de littérature mentionnant une méthode pour leur préparation.
Dans les cas de nouveaux composés, les méthodes de synthése sont mentionnées au sein de la description qui suit. De tels composés sont désignés par l'abréviation c.n. .
Les résultats des tests d'évaluation organoleptique sont donnés dans les exemples spécifiques.
Un autre objet de la présente invention concerne l'utilisation des compositions aromatisantes définies plus haut comme agents modificateurs du goût et de l'arôme de la fumée de tabac.
Les compositions aromatisantes objets de la présente invention peuvent être employées sous diverses formes. La nature, la solubilité et la stabilité de leurs constituants détermineront la forme sous laquelle la composition doit être utilisée. Il est cependant préférable d'utiliser lesdites compositions sous forme de solutions. Une méthode appropriée pour l'aromatisation du tabac consiste en l'aspersion du tabac à l'aide d'une solution alcoolique du produit ou de la composition aromatisante. On peut également utiliser comme solvant des mélanges d'alcool et de propylèneglycol.
Les proportions pour l'emploi des composés alicycliques men tionnés dans des compositions aromatisantes. ou l'utilisation desdites compositions selon l'invention, peuvent varier dans de larges limites. Ces proportions varient selon l'effet organoleptique recherché et selon la provenance du tabac auquel les compositions aromatisantes susmentionnées sont ajoutées. Par exemple, des effets aromatisants intéressants peuvent être obtenus avec des quantités de l'ordre de I à 1000 ppm, quantités basées sur le poids des composés alicycliques mentionnés dans les produits aromatisés terminés. Des effets plus particuliers cependant peuvent être obtenus avec des proportions de 5 et même 10%. On utilise de préférence des quantités comprises entre 10 et 200 ppm. Dans tous les cas, les limites données ci-dessus peuvent bien entendu varier selon l'effet aromatisant recherché.
La présente invention sera mieux illustrée par l'exemple suivant.
Exemple:
7 g d'une solution à 1% de 3.5,5-triméthyl-2,3-époxycyclohexa- 1 ,4-dione dans l'alcool éthylique à 95% ont été dispersés sur 100 g d'un mélange de tabacs du type american blend . Le tabac ainsi aromatisé a ensuite été utilisé pour la manufacture de cigarettes test dont la fumée a été soumise à une évaluation organoleptique, après comparaison de celle-ci avec la fumée de cigarettes témoin , non aromatisées, dont le tabac avait été préalablement traité par de l'alcool éthylique à 95%.
Le groupe d'experts requis a été unanime à déclarer que la fumée des cigarettes test possédait un caractère plus doux et présentait une note herbeuse rappelant le goût de la fumée de cigare.
D'autres échantillons ont été également évalués selon le procédé de l'exemple ci-dessus. Le tableau suivant donne la liste des produits ainsi évalués et mentionne les quantités utilisées pour l'aromatisation recherchée, ainsi que l'arôme développé.

Les quantités indiquées se référent à des quantités de solutions alcooliques à 1% (alcool éthylique 95%).
2 Les caractéres mentionnés se réfèrent aux propriétés organoleptiques des composés testés sur des tabacs et comparés avec des tabacs non aromatisés.
La 4,4,6-triméthylcyclohexa-2,5-diène-2-ol-1-one, composé alicyclique nouveau, peut être préparé ainsi:
a) Un mélange équimoléculaire d'isophorone (13,82 g; 0,1 mole) et de N-bromo-succinimide (17,80 g; 0,1 mole) en présence d'une trace de a, '-azodiisobutyronitrile a été porté à reflux dans 500 ml de CCl4 pendant 15 mn. Après refroidissement, on a ajouté au mélange de réaction environ 500 ml d'éther de pétrole (30-50"C) et filtré le succinimide précipité. Par évaporation des parties volatiles on a obtenu la 3,5,5-triméthyl4-bromo-cyclohex-2éne-one brute.
RMN (CCl4): 1,16 (3H,s); 1,25 (3H,s); 2,11 (3H,s); 2,07 (1H,d,
J= 16cops); 2,53 (1H,d, J= 16 cps); 4,45 (1H,s); 5,78 (lH,s) 6 ppm.
b) 43,4 g de 3,5,5-tnméthyl4-bromo-cyclohex-2-ène-one ont été ajoutés en 30 mn à une solution maintenue à 40"C de triméthylamine-N-oxyde anhydre (32 g) dans 100 ml de chloroforme anhydre.
La réaction était légèrement exothermique et la température du mélange a été maintenue à environ 45 50c C pendant toute l'addition. Après avoir été maintenu à reflux pendant 20 mn, le mélange de réaction a été refroidi et versé sur 110 ml d'H2SO4 dilué à 10%.
La phase organique a été ensuite séparée, lavée à l'eau (3 x), au carbonate de sodium 10% (3 x ) et de nouveau à l'eau (3 x).
L'évaporation des parties volatiles a fourni un résidu qui, par distillation, a donné un produit à éb. 47-60 C/0,001 Torr. Ce produit a été repris avec de l'éther de pétrole (30-50 C), lavé avec une solution aqueuse à 5% de carbonate de soude (2 x) puis à la soude caustique à 2% dans l'eau (5 x ). Les lavages à la soude caustique ont été acidifiés et réextraits immédiatement à l'éther sulfurique.
Après lavage, séchage sur MgSO4 et évaporation des parties volatiles, les extraits éthérés ont fourni 8 g de produit cristallisé ayant une pureté de 95%, suivant l'analyse effectuée par chromatographie en phase gazeuse.
La purification suivante, effectuée par sublimation à 70-80" C/10
Torr, a donné 6 g de 4,4,6-triméthyl-cyclohexa-2,5-diène-2-ol-1 -one.
Le produit a donné un test positif par traitement avec une solution de chlorure ferrique (coloration bleu violette). F. 46"C.

Si, à la place de l'oxyde de triméthylamine, on utilise d'autres oxydes d'une amine aliphatique ou cycloaliphatique tertiaire, des résultats analogues sont obtenus. De même, comme agent halo génant, on peut utiliser, à part le N-bromo-succinimide mentionné, des agents halogénants capables de fournir un halogène positif.
La 3,5,5-triméthyl-2,3-époxy-cyclohexa-1,4-dione peut être préparée comme indiqué ci-dessous:
2 ml d'une solution aqueuse de NaOH 6N ont été ajoutés durant 15 mn, à 15"C, à un mélange de 3,7 g de 3,5,5-triméthyl cyclohex-2-ène-1,4-dione et 8,3 ml d'une solution de péroxyde d'hydrogène à 30% dans 27 ml de méthanol. Le mélange réactionnel a ensuite été agité durant 3 heures à 20-25"C, puis traité avec de l'eau et extrait à l'éther. Les extraits organiques réunis ont été lavés à l'eau jusqu'à neutralité, séchés sur MgSO4 et évaporés, à sec. On obtient ainsi 3,33 g (82%) du produit désiré, éb.

The present invention relates to a flavoring composition for strengthening, improving or modifying the organoleptic properties of tobacco.
It is well known that the tobacco used for the manufacture of cigarettes is essentially composed of a mixture of different types of tobacco which thus give the smoke the particular flavor which is desired. Thus, ordinary cigarettes contain mixtures of tobacco from Virginia, Maryland or Kentucky and oriental or Turkish tobacco, the respective proportions varying according to the particular flavor desired. It is also common to use flavoring substances and humectants, in order to improve the aroma of said tobacco mixtures.
One of the objects of the present invention consists of a composition intended to strengthen, improve or modify the organoleptic properties of tobacco smoke (natural tobacco or tobacco replacement product, of natural or synthetic origin), said flavoring composition being characterized by that it contains at least one of the compounds belonging to the group of the following alkyl derivatives: a) 3,5,5-trimethyl-2,3-epoxycyclohexa-1,4-dione cn
b) 4,4, Strimethylcyclohexa-2,5-diene-2-ol-1-one c.n.
c) 3,5,5-trimethylcyclohex-2-en-2-ol-1-one J. Org. Chem.

Following the designation of each product appears the literature reference mentioning a method for their preparation.
In the case of new compounds, the synthesis methods are mentioned in the description which follows. Such compounds are designated by the abbreviation c.n. .
The results of the organoleptic evaluation tests are given in the specific examples.
Another object of the present invention relates to the use of the flavoring compositions defined above as agents for modifying the taste and aroma of tobacco smoke.
The flavoring compositions which are the subjects of the present invention can be used in various forms. The nature, solubility and stability of their constituents will determine the form in which the composition is to be used. It is, however, preferable to use said compositions in the form of solutions. A suitable method of flavoring tobacco is by sprinkling the tobacco with an alcoholic solution of the flavoring product or composition. Mixtures of alcohol and propylene glycol can also be used as solvent.
The proportions for the use of the alicyclic compounds mentioned in flavoring compositions. or the use of said compositions according to the invention, can vary within wide limits. These proportions vary according to the desired organoleptic effect and according to the origin of the tobacco to which the above-mentioned flavoring compositions are added. For example, interesting flavoring effects can be obtained with amounts of the order of 1 to 1000 ppm, amounts based on the weight of the alicyclic compounds mentioned in the finished flavored products. More particular effects, however, can be obtained with proportions of 5 and even 10%. Amounts of between 10 and 200 ppm are preferably used. In all cases, the limits given above can of course vary according to the flavoring effect sought.
The present invention will be better illustrated by the following example.
Example:
7 g of a 1% solution of 3.5,5-trimethyl-2,3-epoxycyclohexa- 1, 4-dione in 95% ethyl alcohol were dispersed over 100 g of a mixture of tobacco of the American type blend. The tobacco thus flavored was then used for the manufacture of test cigarettes, the smoke of which was subjected to an organoleptic evaluation, after comparison of the latter with the smoke of control cigarettes, unflavored, the tobacco of which had been previously treated with 95% ethyl alcohol.
The requested expert group unanimously declared that the smoke of the test cigarettes had a milder character and had a grassy note reminiscent of the taste of cigar smoke.
Other samples were also evaluated according to the method of the example above. The following table gives the list of products thus evaluated and mentions the quantities used for the desired flavoring, as well as the developed flavor.

The amounts indicated refer to amounts of 1% alcoholic solutions (95% ethyl alcohol).
2 The characteristics mentioned refer to the organoleptic properties of the compounds tested on tobacco and compared with unflavored tobacco.
4,4,6-trimethylcyclohexa-2,5-diene-2-ol-1-one, a new alicyclic compound, can be prepared as follows:
a) An equimolecular mixture of isophorone (13.82 g; 0.1 mol) and N-bromo-succinimide (17.80 g; 0.1 mol) in the presence of a trace of a, '-azodiisobutyronitrile a was refluxed in 500 ml of CCl4 for 15 min. After cooling, about 500 ml of petroleum ether (30-50 ° C) was added to the reaction mixture and the precipitated succinimide filtered off. Evaporation of the volatile parts gave 3,5,5-trimethyl4-bromo. crude cyclohex-2ene-one.
NMR (CCl4): 1.16 (3H, s); 1.25 (3H, s); 2.11 (3H, s); 2.07 (1H, d,
J = 16cops); 2.53 (1H, d, J = 16 cps); 4.45 (1H, s); 5.78 (1H, s) 6 ppm.
b) 43.4 g of 3,5,5-tnmethyl4-bromo-cyclohex-2-ene-one were added over 30 min to a solution maintained at 40 ° C of anhydrous trimethylamine-N-oxide (32 g) in 100 ml of anhydrous chloroform.
The reaction was slightly exothermic and the temperature of the mixture was maintained at about 4550 ° C throughout the addition. After being kept at reflux for 20 min, the reaction mixture was cooled and poured onto 110 ml of H2SO4 diluted to 10%.
The organic phase was then separated, washed with water (3x), 10% sodium carbonate (3x) and again with water (3x).
Evaporation of the volatiles gave a residue which, on distillation, gave a product to eb. 47-60 C / 0.001 Torr. This product was taken up in petroleum ether (30-50 C), washed with a 5% aqueous solution of sodium carbonate (2 x) then with 2% caustic soda in water (5 x ). The caustic soda washes were acidified and immediately re-extracted with sulfuric ether.
After washing, drying over MgSO4 and evaporation of the volatile parts, the ethereal extracts gave 8 g of crystalline product having a purity of 95%, according to the analysis carried out by gas chromatography.
The following purification, carried out by sublimation at 70-80 "C / 10
Torr, gave 6 g of 4,4,6-trimethyl-cyclohexa-2,5-diene-2-ol-1 -one.
The product gave a positive test by treatment with a solution of ferric chloride (violet blue coloration). F. 46 "C.

However, it is to be expected that under other conditions a keto-enolic balance will develop as follows:
EMI2.2
keto-enol diketone
If, instead of trimethylamine oxide, other oxides of a tertiary aliphatic or cycloaliphatic amine are used, analogous results are obtained. Likewise, as the halogenating agent, apart from the mentioned N-bromo-succinimide, halogenating agents capable of providing a positive halogen can be used.
3,5,5-trimethyl-2,3-epoxy-cyclohexa-1,4-dione can be prepared as indicated below:
2 ml of a 6N aqueous solution of NaOH were added over 15 min, at 15 ° C., to a mixture of 3.7 g of 3,5,5-trimethyl cyclohex-2-ene-1,4-dione and 8.3 ml of a 30% solution of hydrogen peroxide in 27 ml of methanol. The reaction mixture was then stirred for 3 hours at 20-25 ° C, then treated with water and extracted with l. 'ether. The combined organic extracts were washed with water until neutral, dried over MgSO4 and evaporated to dryness. In this way 3.33 g (82%) of the desired product is obtained, eb.
