Photochemical preparation of polycycloalkyl oxyalkanes and oxyalkenes

BACKGROUND OF THE INVENTION
East Indian sandalwood oil has heretofore been available only from East Indian sandalwood trees (age-60-80 years). This oil and various individual components of the oil are highly valued perfume bases and are used in large quantities by the perfume industry. The oil, however, is expensive and is in limited and sometimes sporadic, supply. For this reason, a continuous effort has been made to synthesize the various components of sandalwood oil or similar synthetic materials which possess odors similar to the desirable woody fragrance of sandalwood oil.
Synthetic bicyclo(2.2.1) heptanes and the processes for preparing these compounds represent a portion of an extensive scientific effort to prepare compounds having the valuable characteristics of sandalwood. Other processes and compounds relating to the synthesis of synthetic sandalwood oil components are described in the following U.S. Patents:

I. subjecting oil of turpentine to an intense oxidation step comprising continuously insufflating air through said oil at a temperature of about 70.degree. C while agitating said oil and irradiating said oil with ultraviolet light in the presence of:
a. From 0.05 to 0.5 percent by weight of a promoter selected from the group consisting of organic salts and complexes of nickel, vanadium, tungsten, tantalum, niobium, rhenium, tellurium and selenium, and
b. In the presence of from 1 to 10 percent by weight of at least one catalyst selected from the group consisting of:

A paper by Michel Pfau entitled "Photochemistry in the Field of Monoterpenes and Related Compounds" (The Flavour Industry, February, 1972, Page 89-103) discloses, interalia the following reaction sequence: ##STR18##
The compounds described and processes described and the above cited prior art do not suggest the compounds and processes of the instant invention. Indeed nothing in the prior art sets forth such strong sandalwood fragrances as the compounds of the instant invention and no process in the prior art teaches such a commercially feasible process as is set forth herein.
Thus, a complex multi-step process for producing the compound having the structure: ##STR19## is taught by Colonge et al., Bull.Soc.Chim.France 1966, pp. 374-376 ("Synthese de Santatols") and a complex process for producing compounds having the generic structure: ##STR20## is taught in U.S. Pat. No. 3,390,197.

The photooxidation step is preferably carried out in an inert solvent such as methanol or a methanolbenzene mixture in the presence of a reaction sensitizer such as rose bengal and a base such as sodium hydroxide and potassium hydroxide. The photooxidation is carried out by bubbling oxygen through the reaction mass and the time of reaction as well as the rate of reaction is a function of the following variables:
1. Bubble size of oxygen;
2. Throughput of oxygen per unit of time;
3. Pressure;
4. Concentration of base in reaction mass; and
5. Concentration of UV sensitizer in reaction mass.
Higher pressures give rise to longer oxygen residence time thereby permitting shorter times of reaction and greater yields per unit time. Higher concentrations of reaction sensitizer give rise to faster reaction rates:up to sensitizer concentrations of 5 per liter and sensitizer:santalene hydrocarbon ratios 0.5:4, whereat increase in sensitizer concentration does not give rise to any material increase in reaction rate. It is preferable to carry out photooxidation reaction at a temperature of between 15.degree. C and 40.degree. C with room temperature being most convenient.
The epoxidation reaction on one or more of the santalene hydrocarbons, alpha-santalene, beta-santalene and/or epi-beta-santalene is preferably carried out using a peracid such as peracetic acid, perhthalic acid or perbenzoic acid. The reaction is also carried out using an alkali metal lower alkanoate such as sodium acetate in an inert solvent, e.g., methylene chloride. The reaction temperature is preferably -10.degree. C and +10.degree. C with a range of 0.degree.-5.degree. C being preferred. The mole ratio of peracid to santalene hydrocarbon is preferably 1:1 with excess of any reactant giving rise to increased recovery problems. At the end of the reaction, the reaction mass is quenched with water destroying any undesired unreacted peracid. The concentration of santalene in solvent is preferably between 10 and 20% by weight.
The resultant epoxidized santalenes may be used as such in perfumery, or they may be reduced or rearranged to allylic tertiary alcohols or allylic secondary alcohols.
Reduction with strong reducing agents such as lithium aluminum hydride will give rise to one or more tertiary alcohols, as is illustrated in Example III, infra. The reduction of the epoxide using lithium aluminum hydride is preferably carried out in an inert volatile solvent such as diethyl ether at reflux (35.degree. C and atmospheric pressure). It is preferable that the mole ratio of santalene epoxide: lithium aluminum hydride be about 1:1 since excess quantity of either reactant gives rise to high recovery costs and waste of reactant. At the end of the reaction the reaction mass is worked up by addition of an acid salt solution such as saturated ammonium chloride solution.
The rearrangement of the epoxide to the allylic tertiary alcohol is carried out using diphenyl diselenide and sodium borohydride, the mole ratio of diphenyl diselenide; sodium borohydride being preferred to be 1:2 and the mole ratio of sodium borohydride:diphenyl diselenide preferably being about 1:1. This reaction is preferably carried out in an inert anhydrous solvent at reflux temperature; preferably ethanol at 78.degree. C. The reaction mass is preferably refluxed for a period of from one up to five hours in order to ensure complete reaction.
Where it is desired to rearrange the santalene epoxide to form allylic secondary alchohols, the reagent used is a catalytic quantity of aluminum isopropoxide. The reaction is carried out at a temperature in the range of 80.degree. C up to 140.degree. C over a period of between 2 and 6 hours. The preferable ratio of aluminum isopropoxide:santalene epoxide is 1:10 with a range of 1:20 up to 1:5 being workable.
When each of the foregoing reactions is complete, the particular reaction mixture is "worked-up" using routine purification procedures including the unit operations of extractions, crystallization, preparative chromatographic techniques, drying and/or distillation.
The polycycloalkyl oxyhydrocarbons of our invention having key sandalwood oil aroma notes can be used to contribute warm, sandal-like aromas.
Although not found, or found to be existent in relatively low proportions in sandalwood oil, the compounds of our invention are each considered to be at primary sandalwood aroma contributors of all of the constituents of sandalwood oil. Indeed, the relative strength of their aromas ae several-fold that of any other known aroma contributors heretofore found in sandalwood oil; and these properties are unexpected.
As olfactory agents the polycycloalkyl oxyhydrocarbons of this 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, esters, 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 of 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 lowboiling 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 the effect of each ingredient. Thus, the polycycloalkyl oxyhdyrocarbons of this invention, can be used to alter the aroma characteristics of a perfume composition, for example, by highlighting or moderating the olfactory reaction contributed by another ingredient in the composition.
The amount of the polycycloalkyl oxyhydrocarbons of this invention which will be effective in perfume compositions depends on many factors, including the other ingredients, their amounts and the effects which ae desired. It has been found that perfume compositions containing as little as 0.5 percent of the polycycloalkyl oxyhydrocarbons of this invention, or even less, can be used to impart a sandalwood scent to soaps, cosmetics, and the other products. The amount employed can range up to 50% or higher and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and particular fragrance sought.
The polycycloalkyl oxyhydrocarbons of this invention can be used alone or in a perfume composition as an olfactory component in detergents and soaps, 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, as little as 0.01 percent of the polycycloalkyl oxyhydrocarbons will suffice to impart a warm sandalwood aroma. Generally, no more than 0.5 percent is required.
In addition, the perfume composition can contain a vehicle or carrier for the polycycloalkyl oxyhydrocarbons 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 or components for encapsulating the composition.

The following examples I-LXXII are given to illustrate embodiments of the invention as it is presently preferred to practice it. It will be understood that these examples are illustrative, and the invention is not to be considered as restricted thereto except as indicated in the appended claims. It is to be understood that unless otherwise stated all parts, proportions and percentages are by weight. Examples A-D are given herein to set forth methods for preparing raw materials useful as reactants in carrying out the procedures of Examples I-LXXII.
EXAMPLE A
PREPARATION OF MIXTURE OF ALPHA-SANTALENE, BETA-SANTALENE AND EPI-BETA-SANTALENE
a. Saponification of Sandalwood Oil
Into a 50 gallon reaction vessel equipped with agitator, reflux cooling heat exchange, internal steam heating coils and baffles is placed 95 pounds of methyl alcohol. With stirring, 5 pounds of sodium hydroxide flakes are added to the methanol. 100 pounds of sandalwood oil E.I. are then added to the reaction mass which is then heated to reflux (71.degree. C) at atmospheric pressure. The reaction mass is then refluxed at 71.degree. C for a period of 6 hours. The methanol solvent is then stripped off while the pot temperature rises from 71.degree. C up to 100.degree. C. The reaction mass is then cooled to 80.degree. C, and 100 pounds of water are then added thereto. The reaction mass is then acidified to a pH of 5.5 with acetic acid after which it is washed with water thereby bringing the pH to 7.
b. Distillation of Saponified Sandalwood Oil
1,000 pounds of sandalwood oil saponified according to the procedure of part (a) supra is charged to a batch distillation apparatus of the same design as set forth in British Pat. No. 752,784 issued on July 11, 1956. The distillation column has a capacity of 200 gallons.
At 0 reflux and 360 mm Hg pressure, traces of water are removed from the saponified sandalwood oil.
At 3 mm Hg pressure, a head temperature of 80.degree.-100.degree. C, a pot temperature in the range of 155.degree.-160.degree. C, and a reflux ratio of 9:1, 100 pounds of distillate is collected at a distillation rate of 32 pounds/hour.
Two portions of the resulting distillate are then column chromatographed and fractionally distilled as follows:
Portion A-1
50 g of distillate are column chromatographed through 500 g of 5% deactivated SiO.sub.2 with 2 liters of isopentane yielding 35 g of hydrocarbon. This 35 g of hydrocarbon material is then distilled at 0.2 mm Hg pressure using a microvigreux column having a 2 inch head yielding the following fractions:

SYNTHESIS OF ALPHA-SANTALENE
10 grams (0.046 moles) of .pi.-bromotricyclene having the structure: ##STR61## prepared according to the process of Corey et al., J. Am. Chem. Soc. 79, 5773 (1957) in 500 ml of absolute diethyl ether is added to 70 g (2.9 moles) of magnesium in 100 ml of ether during 7 hours. The mixture is heated at reflux for an additional 1.5 hours. The Grignard reagent is filtered through a glass-wood plug into .gamma.,.gamma. -dimethylallyl mesitoate (12.8 g., 0.055 mole, b.p. 95.degree.-100.degree. (0.1 mm.)) in 50 ml of ether. The time required for the addition was 2 hours. The excess magnesium is rinsed with 100 ml of ether and the washing is also added to the ester. The mixture is allowed to stand at room temperature for 96 hours. At the end of this time, a fine white percipitate appears in considerable quantity. To the ether solution is added with stirring a saturated ammonium chloride solution, and stirring is continued until both aqueous and ether layers are clear. The ether solution is washed with 10% sodium hydroxide, water and dried over sodium sulfate. The crude oil (12 g) after evaporation of ether is dissolved in pentane and chromatographed on alumina. The product is eluted with pentane and distilled to give two fractions: no. 1, 1.29 g., b.p. 56.degree.-130.degree. (15-20 mm.), N.sup.25 D 1.4496; no. 2 2.81 g, b.p. 130.degree.-140.degree. (15-20 mm), n.sup.25 D 1.4820. The residue from the distillation which solidified is largely bi-.pi.-tricyclyl. Fraction 2 is redistilled, dissolved in pentane and chromatographed on alumina. The eluate is distilled and yields 1.7 g of oil, b.p. 116.degree.-120.degree. (8 .+-. 2 mm.), n.sup.25 D 1.4822; infrared absorption at 1670, 858 and 840 cm,.sup.- .sup.1 ; alpha.sup.26 D + 18.4.degree. , +17.2.degree. (pure liquid).
Anal. Caled. for C.sub.15 H.sub.24 : C, 88.15; H, 11.84, Found: C, 88.06; H, 12.17.
The above constants for synthetic alpha-santalene agree well with those reported for the purest sample yet isolated from natural sources which had b.p. 116 (6 mm.), n.sup.24 D 1.4855, alpha.sup.24.8 D + 6.60.degree..
EXAMPLE C
PREPARATION OF BETA-SANTALENE
To 400 ml of a freshly prepared 1.2 molar methyl lithium solution in diethyl ether under a nitrogen blanket in a 3-necked flask is added a solution of 2.54 g of endo-3-methyl-exo-3-(4-methyl-3-pentyl)-bicyclo-(2.2.1) heptanone- 2-prepared according to the process of Corey et al., J.Am.Chem.Soc., 84 2611 (1962) in 15 ml of diethyl ether. The mixture is refluxed for 90 hours, decomposed by dropwise addition of water and worked up by separation of the ether layers and evaporation to give an oily product (2.76 g) whose infrared spectrum showed no carbonyl absorption but strong absorption at 2.8u due to hydroxyl. A portion of the crude hydroxy compound (1.535 g) is dissolved in a mixture of 20 ml of methylene chloride and treated at -5.degree. with a solution of 5 ml of thionyl chloride in 5 ml of pyridine. After 10 minutes, 30 ml of pentane is added followed by 132 ml of 3 N hydrochloric acid. The pentane layer is separated, washed, dried and evaporated carefully after passage through a short column of alumina. Distillation of the residue affords 1.10 g of beta-santalene. The infrared and NMR spectra of this material are identical with that of beta-santalene of natural origin. The NMR spectrum (in carbon tetrachloride) shows a sharp peak due to tertiary methyl at 8.97, two peaks (not sharp) due to two methyl groups attached to double bond at 8.43 at 8.36 due to the two olefinic methylene protons (J.sub.H-C-H apparently almost 0) and a broader peak at ca. 5 due to the olefinic proton of the side chain. The characteristics peaks of epi-beta-santalene were completely lacking. Vapor phase chromatographic analysis of samples of the above product and purified natural beta-santalene on a 10 ft tricyanoethoxypropane (TCEP) column (25% on Chromasorb) at 135.degree. shows that these behave identically (and that each was free of epi-beta-santalene). Pure natural beta-santalene is obtained by small scale preparative gas chromatography on the 10 ft TCEP column.

EXAMPLE D
PREPARATION OF EPI-BETA-SANTALENE
The ketone, exo-3-methyl-endo-3-(4-methyl-3-pentenyl)-bicyclo-(2.2.1)-heptanone-2, prepared according to the process of Corey et al., J. Am. Chem. Soc., 84, 2611 (1962), dissolved in 10 ml of anhydrous ether is treated with 21.25 ml (0.034 mole) of 1.6 N methyllithium solution in ether at reflux under nitrogen for 5 days. This is cooled in an ice-bath, hydrolyzed with ice-water and worked up on the usual way to give 0.69 g (9.15%) of the desired hydroxy compound as a pale yellow liquid, showing infrared absorption at 2.71(w), 7.28(m) and 11.25(m) u. A portion of this product (0.223 g) dissolved in 5 ml of anhydrous pyridine and 1 ml of dry methylene chloride is cooled in an ice-salt bath below 0.degree., and treated with a cooled solution of 1 ml of pyridine and 1 ml of thionyl chloride. At the end of the addition, the brown mixture is kept at 0.degree. for 10 minutes and then diluted with 10 ml of pentane followed by 27 ml of 3 N HCl (efficient cooling). The product is extracted with pentane, filtered through a column of alumina using pentane and distilled to give 0.14 g (69%) of epi-beta-santalene as a colorless liquid. The compound showed infrared absorption (in carbon tetrachloride) at 3.2(w), 6.02(m) and 11.3(s) u and on vapor phase chromatography on a 10 ft tricyanoethoxypropane column (25% on Chromasorb) at 135.degree. with a helium flow rate of 33 ml./min. gives a retention time of 37 min. 20 sec. A mixture of the synthetic and the natural (isolated from natural beta-santalene sample) epi-beta-santalene gives a single peak with the same retention time under the above conditions while pure beta-santalene (both synthetic and natural) gave the retention time of 38 min. 55 sec. In the NMR spectrum (in carbon tetrahcloride) the exomethyl proton of the side chain shows up as a single peak at 8.38 and the three olefinic protons show up at 4.92 (side chain), 5.38 (terminal methylene) and 5.61 (terminal ethylene), respectively.
