The general formula (A) represents cyclic cedrene acetal, wherein crimped lines represent alpha-and beta-conformations, R and R1 are the groups as disclosed in the specification, and the compounds are novel. No matter in pure forms or used as three-dimensional isomer compounds, the compounds have the odor characteristics of ambergris and has dispersing and strengthening effects. The effects strengthen various fragrances and prolong the fragrant effect. Thus, the compounds can be beneficially used as perfume or the components of perfume mixtures or essential oil to aromatize cosmetics and industrial products. The compounds in the general formula A usually are conveniently prepared by converting cedrene epoxide (depending on selected reaction conditions) obtained from cedrene into the mixture of isomerized cedrene and diols or individually converting into the mixture of diastereomer cedrene and diols, and then making the mixture react with aliphatic carboxy compounds under the condition of acid catalysis without diluting agents or adding hydrated reagents in aprotic solvent.
Description
The secretory product of animal, gland and other organ-tissue intensive odor characteristics attracted people several thousand deeply.From ancient times, when the fragrance of dispersing is to interrelate with magic originally, and thereby when being used for the purpose of religion and culture, had multiple other application, for example as medicine.In the beginning of this century, Long Yanxiang, Moschus and civet are to occur as composition valuable in the perfume.Therefore, nineteen twenty for the middle period, carried out measuring the analytical work first that dragon prolongs the structure of fragrant main fragrance matter.Then, early thirties has been seen synthetic its work of preparation of technical scale for the first time.Product natural, the plant and animal source can not satisfy for the ever-increasing demand of spices again.Satisfy the ever-increasing demand of high quality spices, smell quality, the stability in technology is used, skin-friendliness, environment protection Harmony toughness also for example can only be by the chemosynthesis of spices.
In order to reach stable environmental balance, wish product on the one hand, if may, constitute by reproducible raw material, on the other hand, be biodegradable.A kind of such natural matter that can obtain in a large number is a cedrene, and it is present in various types of cdear forests.
Before 20 years, prepared a series of (α)-cedrene (1) secondary products and described aromatic property.At its works " spices and sense of smell " (" Riechstoff und Geruchsinn ") [Fragrance and Sense of Smell] (Springer-Verlag, Berlin 1990, ISD-N3-540-52560-2, page 170-172) in, G.Ohloff sums up a series of commercial spices and is derived out by α-Xue Songxi (1).In " spices and seasoning chemistry " (" Perfume andFlavor Chemicals ") (No.593-600,602), S.Arctander has described several by cedrene deutero-spices.
By epoxidation, allylation, esterification and etherificate, the derivative that can be obtained by α cedrene (1) is warm woody odor type (warm-woody odor type) spices from sense organ, has some also to have the effect that dragon prolongs odor type.
According to above-mentioned prior art, in depth studied this field of flavor chemistry especially.Except some had the cedrene derivative of spices character, known had the derivative of large quantities of above-mentioned sesquiterpenes not have or do not have substantially the sense of smell characteristic.For this reason, wondrous especially part is, in this cedrene derivative field, (wherein wave molding is represented α-and β-conformation, R might to have found the compound of the novelty of general formula A as described herein

The invention still further relates to the preparation method of the compound of general formula A, wherein, cedrene epoxide by the cedrene preparation, depend on the selection of reaction conditions, be converted into the mixture of epimeric cedrene glycol, or individually be converted into the mixture of non-mapping cedrene glycol (3a/b), and itself and aliphatic carbonyl compounds under the acid catalysis condition without thinner or in aprotonic solvent, adding under the condition of entry binding reagents and react.
The compound for preparing general formula A, adopt known method the epoxide (2) that (-)-α-Xue Songxi (1) is converted into (-)-α-Xue Songxi (to be seen that organic chemistry puts into practice (Organileum substantially with peracetic acid treatment, Organisch-Chemisches Grundpraktikum[BasicPractical Organic Chemistry]), VEB Deutscher Verlag derWissenschaften, Berlin, 1986, Order No.5714576, page 568).The epoxide (2) that will be obtained by cedrene is converted into the mixture of epimerization glycols (3) with known method (Houben-Weyl) then, and according to different working conditions, this diol mixture has different isomeric distribution and odor effect.Its structure is determined according to the result of NMR.
The ring acetal of the novelty of general formula A, prepared by reacting with aliphatic aldehyde and ketone and acid catalyst use all kinds of SOLVENTS with a kind of known method itself by the glycol (3) that occurs with purified or the form that is rich in or occur as equilibrium mixture, solvent for example is toluene, hexanaphthene, naphtha fraction or diethyl ether.
Epoxide 2a that these epimers are pure and 2b can be converted into non-mapping glycol 3a-f separately or as mixture (depending on working condition).Depend on selected reaction conditions, therefore epimerization epoxide 2a can obtain diastereomeric glycol 3a/b/c/d/e/f/g/h by different amounts than producing with 2b after opening epoxide, and they equally also are different amount ratios.Still constant substantially with aldehyde and reactive ketone neutral body chemistry ratio, therefore the mixing acetal of the novelty of this general formula A is the form of non-enantiomer mixture in this case.
The novelty of these general formulas A is mixed acetal, no matter be respective pure form or as stereoisomer mixture, each all has primary spices character, and can use as spices and perfume oil composition with purified form or as mixture of diastereomers valuably.Fig. 2
