HZC H C C-C H=C H-CH -CH c OH H3C CH3 as having a :sweet, oily-herbaceous, warm odor with floral-balsamic undertones some resemblance to Labdanum notes" Arctander further states that this secondary alcohol has been suggested for use in perfume compositions as a a modifier in various types of floral and non-floral fragrances. It blends well with Labdanum, Lavender, Lavandin, Clary Sage, etc. and it has a refreshing effect upon Rose types. It performs pleasantly with the eliphatic aldehydes into refreshing notes varying from Pine to Rose, and it was at one time used in several types of detergent fragrances. It is produced by reduction of betaionone with sodium alcoholate or by Meerwein-Ponndorf-Verley reduction.

THE INVENTION It has now been discovered that novel aroma imparting compositions having leathery, green, orris, seashore, mimosa, clary sage, woody, fruity, ionone character with a slight musky nuance characteristics may be provided by the utilization of 4-(2,6,6-trimethyl-l ,3- cyclohexadien-l-yl)-2-butanol and/or 4-(6,6-dimethyl- Z-methylene-3-cyclohexen-l-yl)-2-butanol and/or acetates thereof having the generic structure:

wherein R is acetyl or hydrogen and wherein one of the dashed lines represents a carbon-carbon double bond, and the other dashed line represents a carbon-carbon single bond. Thus, the 4-(2,6,6-trimethyl-1,3-cyclohexadien-l-yl)-2-butanol and/or 4-(6,6-dimethyl-2-methylene-3-cyclohexen-l-yl)-2-butanol and/or acetate thereof of our invention are capable of supplying aroma notes usually lacking in many perfumery materials, e.g., orris" and clary sage.

The 4-(2,6,6-trimethyl-1,3-cyclohexadien-1-yl)-2- butanol and/or 4-(6,6-dimethyl-2-methylene-3- cyclohexen-l-yl)-2-butanol and/or acetates thereof may be prepared by first forming dihydro-a-ionol from dihydro-a-ionone according to the following reaction:

l Ll Dlethyl ether The reaction is preferably carried out in an inert solvent such as diethyl ether at reflux temperatures, e.g., theboiling point of the solvent at atmospheric pressure.

The dihydro-a-ionol is then esterified via normal 5 6 esterification procedures according to the following The resulting product, consisting of 70-90% cyclohexreaction: adiene derivative and 30-10% of methylen'e-cyclohex- O ll to form the acetate which is, in turn, dehydrogenated, ene derivative may be used as a perfumery ingredient, using quinoline, preferably in an inert solvent such as as-is or it may be separated (e.g., using gas-liquid chloroform, at temperatures of the order of 5 C up to chromatography techniques) or it may be saponified to +l0C at atmospheric pressure, according to the folthe corresponding alcohol mixture using standard salowing reaction: ponification techniques thus:

I O r t O r i i I" O The saponification is carried using a base (e.g., KOH one NaOH) preferably in.-an alcohol solvent medium (e. g.,=;.

ethanol) at ambient conditions (although temperatures of 50C-60C will cause the saponification' 'reaction to process more rapidly). F

The resulting product, consisting of 70-90% cyclohexadiene derivative and 30-10% methylene cyclohexene derivative may be used in perfumery "a s-is or it may be separated (e.g., using gas-liquid chromatogra phy techniques).

4-(2,6,6-trimethyl-l ,3-cyclohexadien-1-yl)-2- butanol and/or 4-(6,6-dimethyl-2-methylene-3- cyclohexen-l-yl)-2-butanoland/or 4-(2,6,6-trimethyll,3-cyclohexadien-l-yl)-2-butyl acetate and/or4-(6,6-'

When used as an olfactory component of a perfumed "article as little as l'parts per million of the 4-(2,6,6-

tate and an auxiliary perfume ingredient including, for example, alcohols, aldehydes, nitriles, esters, cyclic evaporation; and (d) topnotes which are usually low boiling fresh smelling materials.

In perfume compositions, the individual component will contribute its particular olfactory characteristics but the over-all effect of the perfume composition will be the sum of the effects of each of the ingredients. Thus, 4-(2,6,6-trimethyl-1,3-cyclohexadien-l-yl)-2- butanol and/or 4-(6,6-dimethyl-2-methylene-3- cyclohexen-l-yl)-2-butanol and/or 4-(2,6,6-trimethyla l,3-cyclohexadien-l-yl)-2-butyl acetate a'nd/or 4'-'(6,6-

dimethyl-2-methylene-3-cyclohexen-1-yl)-2-butyl acetate can be used to alter the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.

The amount of the 4-(2,6, 6-trimethyl-l,3-cyclohexadien-l -yl)-2-butanol and/or 4-(6,6-dimethyl-2-methylene-3-cyclohexen-l-yl)-2-butanol and/or 4-(2,6,6- trimethyl-l ,3-cyclohexadien-l-yl)-2-butyl acetate and- /or 4-(6,6-dimethyl-2-methylene-3-cyclohexen-lyl)-2- butyl acetate of our invention which will be effective in perfume compositions depend on 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 0.05% or 4-(2,6,6- trimethyl-l ,3-cyclohexadienl -yl)-2-butanol and/or 4-(6,6-dimethyl-2-methylene-3-cyclohexen-l -yl )-2- butanol and/or 4-(2,6,6-trimethyl-.l,3-cyclohexadienl-yl)-2-butyl acetate and/or 4-(6,6-dimethyl-2- methylenecyclohexen-l -yl)-2-butyl acetate or even less canbe used to impart a floral, seashore, clary sage, orrisy type scent odor to soaps, cosmetics and other products. The amount employed can range up to 80% of the fragrance components and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.

4-( 2,6,6-trimethyl- 1 ,3-cyclohexadienl -yl )-2- butanol and/or 4-(6,6-dimethyl-2-methylene-3- cyclohexen-l-yl)-2-butanol and/or 4-(2,6,6-trimethyll,3-cyclohexadien-l-yl)-2-butyl acetate and/or 4-(6,6-

by the instant invention, such materials can be comdimethyl-2-methylene-3 -cyclohexe,n l-'-yl):;2-butyl acetate are useful in perfume compositions as olfactorycomponents in detergents and soaps; space odorants and deodorants; perfumes; colognes; toilet water; bath preparations such as bath oils and bath solids; hair preparations such as lacquers, brilliantines, pomades andshampoo; cosmetic preparations such as creams,

trimethyl-l,3-cyclohexadien-1-yl)-2-butanol and/or 4-(6,6 dirnefhyl-2 tne'thylene-3-cyclohexen-l-yl) 2- butanol and/or "4-'(2,6,6'-'trimethyl-l ,3-cyclohexadienl-yl') 2-butyl acetate and/or 4-(6,6-di methyl-2 methy lene '3-cyclohe'xen 'l yl)-2'-butyl acetate will suffice 'to impart a low keyed floral, seashore, clary sage, orrisy character which is one of the key odor characteristics ofmimosa and orris perfume formulations. Generally, no more than 0.5% of 4-(2,6,6-trimethyl-l ,3- cyclohexadien-l-yl)-2-butanol and/or 4-(6,6-dimethyl- 2-methylene-3-cyclohexen-l-yl)-2-butanol and/or 4- (2,6,6-trimethyl-l,3-cyclohexadien l-yl)-2-butyl acetate and/or 4-(6,6-dimethyl-2-methylene-3-cyclohexen-l-yl)-2-butyl acetate based on. the ultimate end product is required in the perfume composition.

In addi tion, the perfume composition or fragrance composition of this invention contains a vehicle or carrier for the 4-(2,6,6-trimethyl-1,3-cyclohexadien-l-- yl)-2-butanol and/or 4-(6,6-dimethyl-2-methylene3- cyclohexen-l-yl)-2-butanol and/or 4-(2,6,6-trimethyll,3-cyclohexadien-l-yl)-2-butyl acetate and/or 4-(6,6- dimetlfyl-2-methylene-3-cyclohexen-l-yl)-2-butyl acetate. The vehicle can be a liquid such as an alcohol, a nontoxic alcohol, a non-toxic 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 (such as gelatine).

It will thus be apparent that 4-(2,6,6-trimethyl-l ,3- cyclohexadien-l-yl)-2-butanol and/or 4-(6,6-dimethyl- Z-methylene-3-cyclohexen-l-yl)-2-butanol and/or 4- (2,6,6-trimethyl-l,3-cyclohexadien-l-yl)-2-butyl acetate and/or 4-(6,6-dimethyl-2-methylene-3-cyclohexen-l-yl)-2-butyl acetate can be utilized to alter the sensory properties, particularly organoleptic properties such as flavor and/or fragrances of a wide variety of consumable materials.

(0. moles) The resulting mixture is cooled to 5C and 80 gm of bromine (0.5 moles) in 125 ml of chloroform is added to the reaction mass over a period of two hours, while maintaining the temperature thereof in the range of 0-5C. After bromine addition, the reaction mass is stirred for one hour at 5C and then allowed to warm up to room temperature. The chloroform solvent is then removed at reduced pressure and the resulting residue is heated using a steam bath for 3 hours, with N,N dimethylaniline. The reaction mass is then cooled and 30 ml pyridine is added. The reaction mass is then heated for a period of 30 minutes using the steam bath.

The resulting mixture is cooled and then added to a mixture of 600 ml n-pentane and 600 ml 5N hydrochloric acid. The resulting mixture now exists in two phases; an aqueous phase and an organic phase. The aqueous phase is extracted with three 100 ml portions of n-pentane. The pentane portions are combined with the organic phase and the resulting material is washed as follows:

i. Twice with 5N hydrochloric acid ii. Twice with 10% sodium bicarbonate solution iii. Twice with saturated sodium chloride solution The resulting material is then dried over anhydrous magnesium sulfate and evaporated yielding 94.3 gm of AA i1 crude. The crude materialis distilled on a microvigreaux columritat 9396C and a pressure of 0.6-0.9 mm Hg. IR, NMR; and mass spectral analyses yield the information that the material is a mixture of compounds having the structures:

The weight ratio of cyclohexadiene derivative: methy- Iene cyclohexene derivative is 65:18. This material has a woody, fruity, leathery, ionone, seashore, fatty aroma with a slight musky nuance.
