9 EXAMPLE I Reaction:
Heat
ether One liter of diethyl ether is added to a three liter reaction flask equipped with reflux condenser, stirrer, thermometer, nitrogen purge, addition funnel and heating mantle. 10 Grams of lithium aluminum hydride is then added slowly to the diethyl ether. 130 Grams of dihy dro-a-ionone in 400 ml diethyl ether is then added to the lithium aluminum hydride-diethyl ether mass over a period of 1.5 hours. The rate of addition is adjusted to promote and continue refluxing. After the addition of other dihydro-a-ionone is complete, the reaction mass is refluxed using heat provided by a heating mantle. The reaction mass is thencooled to 5C and the eircess lithium aluminum hydrideis decomposed with 50 ml of water. I
The resulting precipitate is vacuum filtered and the aqueous layer is separated from the organic (ether) layer. The resulting organic phase is thenv washed twice with 100 ml portions of saturated aqueous sodium chloride solution, and dried over anhydrous magnesium sulfate. The ether is then evaporated yielding 110 gm. 5
residue, confirmed by IR analysis to bean alcohol having the structure:

Five 50 ml portions of 5% aqueous sodium carbonate solution; and i ii. Two 100 ml portions of saturated NaCl solution; The ether extracts are then dried over anhydrous magnesium sulfate, and evaporated leaving 121 gm. of residue, as ester having the structure: 1
EXAMPLE III PREPARATION OF DEl-IYDRODIHYDROIONOL ACETATE FROM DIHYDROIONOL ACETATE Reaction: f
(i) Dihydro-wlonol prepared according to the process of Example [1 (ii) Chloroform (iii) Quinoline 120.0 gm. (0.5 moles) 500 ml 65 m. (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.
EXAMPLE IV SAPONlFlCATlON OF DEHYDRODIHYDROIONOL ACETATE TO FORM DEHYDRODIHYDROIONOL Reaction:
The following materials are added to a two liter flask equipped with stirrer and thermometer:
The resulting mixture is stirred for a period of 15 hours and then neutralized with 80 ml of 5N hydrochloric acid. The ethyl alcohol is removed underreduced pressure at 50C and the reaction mass is then diluted with 200 ml of diethyl ether. The reaction mass is then washed with two 100 ml portions of saturated sodium chloride solution, after which the ether is evaporated yielding a 51.2 g of crude product. The crude product is distilled on a microvigreaux column at 89- 90C and a pressure of 0.7-1 mm Hg pressure to yield a mixture of compounds having the structures:
These structures are confirmed by GLC, mass spectral and IR analyses. The weight ratio of cyclohexadiene derivativezmethylene cyclohexene derivative is 65:18. The mixture is separableby means of GLC separation. The mixture as well as the two major individual components thereof have a leathery, green, seashore, orris, minosa, clary sage aroma with a slightly musky nuance.
