Description

BACKGROUND OF THE INVENTION

The present invention relates to substituted norbornene ether derivatives of the genus of compounds having the structures: ##STR2## wherein R represents C.sub.3 -C.sub.6 alkyl; aralkyl; hydroxy alkyl; and alkoxy alkyl, and uses thereof in order to alter, modify or enhance the aroma of consumable materials.

There has been considerable work performed relating to substances which can be used to impart (modify, augment or enhance) fragrances to (or in) various consumable materials. These substances are used to diminish the use of natural materials, some of which may be in short supply and to provide more uniform properties in the finished product.

Long-lasting, fresh, green bean, rosey, citrus, petitgrain-like, fruity, anisic, green, raw potato-like, twiggy, herbaceous, sweet, sweaty, green pea-like, chocolate-like, carrot-like and creamy aroma nuances with galbanum topnotes and anther-like and anise-like undertones are desirable in several types of perfume compositions, perfumed articles and colognes.

The perfume use of norbornene alcohol and ester derivatives having the structures: ##STR3## wherein R.sub.1 is C.sub.1 -C.sub.4 alkyl is disclosed in U.S. Pat. No. 3,860,635 particularly at Example XV at column 16 thereof. Such compounds and the synthesis thereof are also disclosed by Bobyleva, Zh. Org. Kh. Volume 13, No. 10, pages 2085-92, October 1977.

In addition, ethers of norbornene derivatives having the structures: ##STR4## are disclosed as well as the process for preparing same according to the reaction: ##STR5## in Shield, Can. J. Chem. Volume 49, 1971, page 1142.

U.S. Pat. No. 3,927,116 indicates the utility of certain vinyl norbornyl ethers having the structure: ##STR6## wherein R.sub.2 represents C.sub.1 -C.sub.4 alkyl as being intermediate for the preparation of detergents at column 9 lines 10-15. No indication in U.S. Pat. No. 3,927,116 of the use of such compounds in perfumery, for augmenting or enhancing the aroma of perfumes, perfumed articles and colognes, is suggested either implicitly or explicitly in U.S. Pat. No. 3,927,116.

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1(A) is the GLC profile for the reaction product produced according to Example I(A) and contains starting material having the structure: ##STR49## as well as reaction products: ##STR50## Reference 1 indicates the peak of this GLC profile which consists of the compound having the structure: ##STR51## Reference 2 indicates the peak of the GLC profile which consists essentially of the compound having the structure: ##STR52## Reference 3 indicates the peak of the GLC profile which consists essentially of the compound having the structure: ##STR53##

The instant invention relates to the use for augmenting or enhancing the aroma of perfumes, perfumed articles and colognes of compunds having the generic structures: ##STR54## either taken alone or in admixture wherein R represents C.sub.3 -C.sub.6 alkyl; aralkyl; hydroxy alkyl; and alkoxy alkyl.

These compounds as a group have long lasting, fresh, green bean, rosey, citrus, petitgrain-like, fruity, anisic, green, raw potato-like, twiggy, herbaceous, sweet, sweaty, green pea-like, chocolate-like, carrot-like and creamy aroma nuances with galbanum topnotes and anther-like and anise-like undertones.

The compounds of our invention may be prepared by reacting ethylidene norbornene having the structure: ##STR55## with ROH, and alcohol wherein R represents C.sub.3 -C.sub.6 alkyl; aralkyl; hydroxy alkyl; and alkoxy alkyl in the presence of a catalyst which is either a mineral acid or a Lewis acid. Examples of mineral acid catalysts are sulfuric acid, phosphoric acid, para-toluene sulfonic acid, methane sulfonic acid and acid ion-exchange resin. Examples of Lewis acid which can be use as catalysts are boron trifluoride etherate, aluminum chloride, zinc chloride, stannic chloride, stannouse chloride, zinc bromide, diethyl aluminum chloride, ethyl aluminum dichloride, ethyl aluminum dibromide and diethyl aluminum bromide. The reaction preferably takes place in the presence of an inert sorvent such as tetrahydrofuran, toluene or benzene. The reaction may take place in the absence of the inert solvent and in the presence of an excess of the alcohol reactant, the excess of the alcohol reactant being used as the "solvent".

The reaction temperature may vary from about 25.degree. C. up to 120.degree. C. with reflux temperature being preferred. The reflux temperature depends upon the pressure in the reactor and the particular solvent being used as well as its concentration. The mole ratio of acid catalyst to ethylidene norbornene may vary from about 1:99 up to about 1:10. The mole ratio of ethylidene nobornene reactant to ROH alcohol reactant may vary from about 1:1 up to about 1:2 with a mole ratio of 1:1.5 of norbornene: alcohol reactant being preferred. Thus, the reaction to produce the compounds of our invention may be shown thusly: ##STR56##

The compounds of our invention are usually prepared in admixture with compounds having the generic structure: ##STR57## being prepared along with compounds having the structure: ##STR58## These compounds, however, may be separated by distillation, extraction and preparative GLC techniques in order to yield separately compounds having the structure: ##STR59## and separate therefrom compounds having the structure: ##STR60##

In addition, the compounds having the structure: ##STR61## exist in isomeric forms and are produced in admixture. The mixture of these "endo" and "exo" and "cis" and "trans" isomers may be separated from one another by means of standard separation techniques including preparative GLC techniques whereby the individual isomers may be separated and then utilized individually. Structures of these isomers are as follows: ##STR62##

Specific examples of the compounds produced according to the foregoing process and useful for the practice of my invention are set forth in table I below.

The norbornyl ether derivative(s) and one or more auxiliary perfume ingredients, including, for example, hydrocarbons, alcohols, ketones, aldehydes, nitriles, esters, lactones, ethers other than said norbornyl ether derivative(s), hydrocarbons, synthetic essential oils and natural essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in citrusy and/or green woody and/or piney fragrances. Such perfume compositions usually contain (a) the main note or the "bouquet" or foundation stone of the composition; (b) modifiers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and (d) topnotes which are usually low boiling fresh smelling materials.

In perfume compositions, it is the individual components which contribute to their particular olfactory characteristics, however the over-all sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, one or more of the norbornyl ether derivative(s) of our invention can be used to alter, modify or enhance the aroma characteristic of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.

The amount of norbornyl ether derivative(s) of our invention which will be effective in perfume compositions as well as in perfumed articles and colognes depends upon many factors, including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.005% of norbornyl ether derivative(s) or even less (e.g. 0.002%) can be used to impart fresh, green bean, rosey, citrus, petitgrain-like, fruity, anisic, green, raw potato-like, twiggy, herbaceous, sweet, sweaty, green pea-like, chocolate-like, floral, carrot-like and creamy aroma nuances with galbanum topnotes and anther-like and anise-like undertones to soaps, cosmetics, detergents (including anionic, non-ionic, zwitterionic and cationic solid or liquid detergents) or other products. The amount employed can range up to 70% of the fragrance components and will depend upon considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.

The norbornyl ether derivative(s) of our invention are useful (taken alone or together with other detergents in perfume compositions) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath preparations such as lacquers brilliantines, pomades and shampoos; cosmetic preparations, such as creams, deodorants, hand lotions and sun screens; powders such as talcs, dusting powders, face powders and the like. As little as 0.25% of the norbornyl ether derivative(s) will suffice to impart an intense green, petitgrain-like, rosey and citrusy notes to citrusy, woody, floral and piney perfume formulations. Generally, no more than 5% of the norbonyl ether derivative(s) based on the ultimate end product is required to be used as is or in the perfume composition.

Furthermore, as little as 0.25% of the norbornyl ether derivative(s) will suffice to impart such aroma to perfumed articles per se, whether in the presence of other perfume materials or whether used by itself. Thus, the range of use of the norbornyl ether derivative(s) of our invention in perfumed articles may vary from 0.25% up to 5% by weight based on the total weight of the perfumed article.

In addition, the perfume composition or fragrance composition of our invention can contain a vehicle, or carrier for the norbornyl ether derivative(s). The vehicle can be a liquid such as a non-toxic alcohol, e.g. ethanol, a non-toxic glycol, e.g. propylene glycol or the like. The carrier can also be an absorbent solid, such as a gum, (e.g. gum arabic), or components for encapsulating the composition by means of coacervation (such as gelatin).

It will thus be apparent that the norbornyl ether derivative(s) of our invention can be utilized to alter, modify or enhance aroma of perfume compositions, colognes or perfumed articles.

Examples I-XI, following, serve to illustrate processes for specifically producing the norbornyl ether derivative(s) useful in our invention.

The following examples in general, serve to illustrate specific embodiments of our invention. It will be understood that these examples are illustrative and the invention is to be considered restricted thereto only as indicated in the appended claims. All parts and percentages given herewith are by weight unless otherwise specified.
