Description
BACKGROUND OF THE INVENTION
This invention relates to oxobicyclononane derivatives defined according to the structure: ##STR2## wherein R represents methyl or ethyl; one of the dashed lines represents a carbon-carbon single bond or a carbon-carbon double bond; N and P each represents 0 or 1; the sum of N and P being equal to 1; with the proviso that when N is 1, the dashed line at the "2-3" position is a carbon-carbon single bond and the dashed line at the "6-7" position is a carbon-carbon double bond and uses thereof in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles.
Also covered by this invention are the precursor formates defined according to the structure: ##STR3## wherein the dashed lines, N and P are defined, supra.
Materials which can provide strawberry aromas with green banana topnotes are highly desirable in the art of perfumery. Many of the natural substances which provide such fragrance nuances and contribute the desired nuances to perfumery compositions are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.
The prior art contains a large number of teachings regarding the use of organic carbonates in augmenting or enhancing the aroma of perfumes. Thus, U.S. Pat. No. 4,033,993 discloses the use of organic carbonates defined according to the structure: ##STR4## wherein R.sub.1 is a moiety having from 8 to 12 carbon atoms selected from the group consisting of alkylcyclohexyl, alkenylcyclohexyl, alkynylcyclohexyl and cycloalkyl and R.sub.2 is a moiety selected from the group consisting of alkyl having from 1 to 5 carbon atoms, alkenyl having from 2 to 5 carbon atoms and alkynyl having from 2 to 5 carbon atoms. U.S. Pat. No. 4,033,993 describes, for example, methyl-1-ethynycyclohexyl carbonate having a fruity, herbal complex odor and distinct fragrance of dill. In addition, U.S. Pat. No. 4,033,993 describes methyl cyclooctyl carbonate as having a herbal, natural and complex fragrance which is distinguished by a strong and long clinging flowery jasmine scent and further indicates its use in jasmine perfume compositions. U.S. Pat. No. 4,033,993 describes the preparation of the compounds defined according to the structure: ##STR5## according to the reaction: ##STR6## wherein R.sub.1 and R.sub.2 are defined as above.
In addition, U.S. Pat. No. 4,080,309 describes the perfume use of the carbonates defined according to the structure: ##STR7## wherein R.sub.1 ' is a moiety having from 8 to 12 carbon atoms selected from the group consisting of alkylcyclohexyl, alkenylcyclohexyl, alkynylcyclohexyl and cycloalkyl and R.sub.2 ' is a moiety selected from the group consisting of alkyl having from 1 to 5 carbon atoms, alkenyl having from 2 to 5 carbon atoms and alkynyl having from 2 to 5 carbon atoms. Described in U.S. Pat. No. 4,080,309 are also such compounds as methyl cyclooctyl carbonate and the use thereof in jasmine perfume formulations. As is the case in U.S. Pat. No. 4,033,993, the carbonates of 4,080,309 are indicated to be prepared according to the reaction: ##STR8##
4-Cyclooctenyl alkyl carbonates defined according to the structure: ##STR9## wherein R.sub.4 is methyl or ethyl and reaction products including a major proportion of said 4-cyclooctenyl alkyl carbonates and a minor proportion of bicyclooctanyl carbonates having the structure: ##STR10## wherein R.sub.5 is methyl or ethyl and uses thereof in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles are described in U.S. Pat. No. 4,452,730 issued on June 5, 1984.
Tricyclodecane carbonates having the structures: ##STR11## are described as having fruity (apple), anisic-like aromas with dry, hay-like and berry-like undertones.
However, nothing in the prior art describes the oxobicyclononane derivatives of our invention or the organoleptic utilities thereof.

THE INVENTION
The present invention provides compounds having the structure: ##STR33## wherein Z represents alkoxy carbonyl or formyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein M and Q each represents 0 or 1 with the proviso that the sum of M+Q is 1 and with the further proviso that M is 1 when the dashedd line at the "2-3" position is a carbon-carbon single bond and the dashed line at the "5-6" position is a carbon-carbon double bond and Q is 1 when the dashed line at the "5-6" position is a carbon-carbon single bond and the dashed line at the "2-3" position is a carbon-carbon double bond including the genuses having the structures: ##STR34## wherein R represents methyl or ethyl; N and P each represents 0 or 1; each of the dashed lines represents a carbon-carbon single bond or a carbon-carbon double bond with the provisos:
(i) the sum of N+P=1;
(ii) when N is 1 the dashed line at the "2-3" position is a carbon-carbon single bond and the dashed line at the "6-7" position is a carbon-carbon double bond and when P is 1 the dashed line at the "6-7" position is a carbon-carbon single bond and the dashed line at the "2-3" position is a carbon-carbon double bond.
The compounds covered by the genus having the structure: ##STR35## (carbonates) have utilities in perfumery; that is, in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles including solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, cosmetic compositions, hair preparations and perfumed polymers. The compounds covered by the genus having the structure: ##STR36## are useful as intermediates or precursors in forming the genus having the structure: ##STR37##
The compounds defined according to the genus: ##STR38## have a strawberry aroma with green banana topnotes.
The present invention also provides an economically efficient process for synthesizing the compounds defined according to the structure: ##STR39## by first reacting bicyclononadiene having the structure: ##STR40## with formic acid according to the reaction: ##STR41## and then reacting the resulting formate compound with the carbonate having the structure: ##STR42## (wherein R represents methyl or ethyl) according to the reaction: ##STR43##
The bicyclononene formate is formed from bicyclononadiene by reaction of bicyclononadiene with formic acid. The reaction is carried out at reflux conditions for a period sufficient to yield a product containing greater than 80% bicyclononene formate. The mole ratio of formic acid:bicyclononadiene may vary between about 2:1 up to about 7:1 with a preferred mole ratio of between 5.5:1 and 6:1 of formic acid:bicyclononadiene. At the end of the reaction the reaction product, the bicyclononene formate is distilled. The crude reaction product contains the compounds having the structures: ##STR44## with the majority of the mixture being the compounds having the structures: ##STR45## The compound having the structure: ##STR46## is separated out from the reaction mass by fractional distillation leaving the compounds having the structures: ##STR47##
These compounds may be separated from one another whereby the group of compounds having the structures: ##STR48## may be separated from the group of compounds having the structures: ##STR49## by preparative liquid chromatography. However, from a practical standpoint the fractional distillation product is sufficient for the purposes of use of the resulting bicyclononenyl formates as intermediates in preparing carbonates which are subsequently useful in perfumary.
The resulting mixture of compounds having the structures: ##STR50## is then reacted with either diethyl carbonate or dimethyl carbonate defined according to the structure: ##STR51## wherein R represents methyl or ethyl in the presence of an alkali metal alkoxide catalyst such as sodium methoxide, sodium ethoxide, sodium isopropoxide, potassium t-butoxide as well as other metal alkoxides such as aluminum isopropoxide. The reaction temperature may vary between 50.degree. C. and 90.degree. C. with a preferred reaction temperature of between 60.degree. and 80.degree. C.
The mole ratio of dialkyl carbonate to bicyclononenyl formate may vary from about 2:1 up to about 4:1 with a preferred mole ratio of about 2.8:1. The concentration of alkali metal alkoxide or other metal alkoxide in the reaction mass may vary from about 0.03 moles per liter up to about 0.5 moles per liter with a preferred concentration of alkali metal alkoxide or other metal alkoxide in the reaction mass being about 0.05 moles per liter. At the end of the reaction the reaction mass is quenched with weak acid such as acetic acid. The reaction mass is then fractionally distilled thereby recovering a mixture of carbonates having the structures: ##STR52## with the major (e.g., greater than 75%) portion of carbonates having the structures: ##STR53## The group of carbonates having the structures: ##STR54## may be separated by preparative liquid chromatography from the group of carbonates having the structures: ##STR55## However from a practical standpoint it is preferable not to so separate the fractional distillation products but to use such fractional distillation products "as is" for their organoleptic properties in perfumery, e.g., augmenting or enhancing the aroma of perfume compositions, perfumed articles and colognes.
As stated, supra, the oxobicyclononane derivatives of our invention can be used to contribute strawberry aromas with green banana topnotes to perfume compositions, perfumed articles and colognes with the perfumed articles being such materials as solid or liquid anionic, cationic, nonionic or zwitterionic detergents, perfumed polymers, fabric softener compositions, fabric softener articles, optical brighteners, fabric conditioners, hair preparations, shampoos and hair sprays. As olfactory agents the oxobicyclononane derivatives of our invention can be formulated into or used as components of a "perfume composition".
The term "perfume composition" is used herein to mean a mixture of organic compounds including, for example, alcohols, aldehydes, ketones, nitriles, ethers, lactones, esters other than the carbonates of our invention and frequently, hydrocarbons which are admixed so that the combined odors of the individual components produce a pleasant or desired fragrance. 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) top notes which are usually low-boiling, fresh-smelling materials.
In perfume compositions, the individual component will contribute its particular olfactory characteristics, but the overall effect of the perfume composition will be the sum of each of the effects of each of the ingredients. Thus, the individual compounds of this invention or mixtures thereof can be used to alter the aroma characteristics of the perfume composition, for example, by highlighting or moderating the olfactory reaction contributed by another ingredient in the composition.
The amount of oxobicyclononane derivative(s) of our invention which will be effective in perfume compositions 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 0.1% of the oxobicyclononane derivative(s) of our invention or even less and perfume compositions containing as much as 70% of one or more of the oxobicyclononane derivative(s) of our invention can be used to impart interesting, strawberry-like aromas with green banana topnotes to perfumed articles, perfume compositions and colognes. Such perfumed articles include fabric softener compositions, drier-added fabric softener articles, cosmetic powders, talcs, solid or liquid anionic, cationic, nonionic or zwitterionic detergents and perfumed polymers. The amount employed an range up to 70% as stated, supra and will depend on considerations of cost, nature of the end product and the effect desired on the finished product and particular fragrance sought.
Thus, one or more of the oxobicyclononane derivative(s) of our invention can be used alone or in a perfume composition as an olfactory component, in solid or liquid anionic, cationic, nonionic or zwitterionic detergents (including hand soaps) perfumed polymers (those which are microporous and those which are macroporous and contain particulate absorbent fillers such as talc), space odorants and deodorants; perfumes, colognes, toilet waters, bath salts, hair 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.
When used as an olfactory component of a perfumed article such as a microporous polymer or a macroporous polymer containing an absorbent filler or such as a solid or liquid cationic, anionic, nonionic or zwitterionic detergent or of a cosmetic powder, as little as 0.01% of one or more of the oxobicyclononane derivative(s) of our invention will suffice to provide an interesting strawberry-like aroma with green banana topnotes. Generally, no more than 0.8% of one or more of the oxobicyclononane derivative(s) of our invention is required. Thus, the range of oxobicyclononane derivative(s) in perfumed articles may vary from about 0.01% up to about 0.8%.
In addition, the perfume compositions of our invention can contain a vehicle or carrier for the oxobicyclononane derivative(s) of our invention alone or with other ingredients. The vehicle can be a liquid such as an alcohol such as ethanol, a glycol such as propylene glycol or the like. The carrier can be an absorbent solid such as a gum (e.g., xanthan gum or gum arabic) or components for encapsulating the composition as by coacervation using gelatin or by forming a polymeric shell around a liquid perfume center by means of the use of a urea formaldehyde prepolymer.
The following Examples I and II set forth processes for preparing the oxobicyclononane derivatives of our invention Examples following Example II set forth methods for using the oxobicyclononane derivatives of our invention for their organoleptic properties.
Unless otherwise indicated, all parts and percentages are by weight.
