Description
Procédé pour la préparation de composés carbonylés polycycliques
Le brevet principal No 497360 a pour objet un procédé pour la préparation des composés de formule:
EMI1.1
lequel consiste à oxyder le thuyopsène de formule:
EMI1.2
par a) un peracide, ou b) un dérivé oxydé d'un élément de transition pour obtenir directement le composé
I, ou c) l'oxygène gazeux en présence de radiations actiniques, l'intermédiaire II de formule:
EMI1.3
formé étant alors isomérisé par un acide, pour obtenir I. La formule I représente une cétone tricyclique, la thuyopsanone; elle comprend différents isomères configurationnels dont l'existence résulte de la présence de centres d'asymétrie.
On a trouvé que les composés de formule I, qui sont particulièrement stables en milieu alcalin, sont doués de propriétés organoieptiques intéressantes et sont utilisés avantageusement dans la préparation de parfums et produits parfumés.
On a maintenant trouvé que si les composés de formule:
EMI1.4
sont obtenus par oxydation du thuyopsène au moyen d'un peracide on peut opérer par un procédé caractérisé en ce que:
a) l'on sépare par cristallisation du mélange réactionnel contenant les composés de formule I déjà formés un glycol monoacylé de formule:
EMI1.5
dans laquelle R représente le reste acyle dérivé du peracide utilisé;
b) l'on chauffe ledit solide aux alentours de son point d'ébullition pour donner un mélange de thuyopsanone et des alcools de formule:
EMI1.6
c) on isomérise les alcools de formule II au moyen d'un agent acide pour fournir la thuyopsanone pure.
li est également possible d'utiliser le glycol monoacylé III, obtenu selon le procédé décrit sous lettre a), comme produit de départ pour la préparation d'un com posé de formule I: ledit glycol est alors saponifié en diol correspondant qui, après traitement par un agent acide, est converti en thuyopsanone.
L'exemple suivant sert à illustrer l'invention d'une manière plus détaillée. Dans ledit exemple, les températures sont indiquées en degrés centigrades.
Exemple:
Préparation de la (-)-thuyopsanone-(3)
et de l'(-)-sothuyopsanone-(3)
a) Chauffage de l'acétate du glycol:
L'acétate du glycol (long), préparé suivant la méthode décrite au paragraphe c), a été soumis à 2 distillations successives entre 145 et 1600. Par titration d'une aliquote du produit distillé on a constaté que la quantité théorique d'acide acétique a été libérée. On a lavé le distillat jusqu'à neutralité, puis on l'a soumis à l'analyse chromatographique en phase gazeuse qui a mis en évidence l'existence d'un mélange environ 1:1 de thuyopsanone (2 isomères) et de l'alcool de formule IIa.
EMI2.1
Ce mélange a été utilisé sans autre dans la suite des opérations. Rendement pratiquement quantitatif.
b) Isomérisation du composant de formule lia:
Le mélange de thuyopsanone et de l'alcool lia (130 g) préparé suivant la méthode décrite au paragraphe a) a été dissous dans 160 ml d'alcool. 50 ml de H2SO4 (50 o/o) ont été ajoutés et la solution a été agitée 4 heures à 400.
En cas de trouble, on a dilué avec encore un peu d'alcool. On a dilué à l'eau et extrait à l'éther de pétrole (50-7oe). Après le traitement habituel de l'extrait, on a obtenu par distillation 120 g de thuyopsanone pratiquement pure contenant la (-)-thuyopsanone-(3) et l'(-)-isothuyopsanone dans un rapport approximativement 1:1.
(-)-thuyopsanone-(3): F. 680. Spectre U.V. (EtOH): 2010A (e = 339,9), 2830 A (e = 28,5). Spectre RMN (Varian HA-100): 0,64 (3vs), 1,2 (3H,d, J = 0,7 cps), 1,1 et 1,2 (2 X 3H,s), 0,6-0,8 (2H, bande large), 1,3-1,9 (7H), 2,1-2,3 (2H,d, J = 1,5 cps), 2,3-2,55 (1H, bande large) 6 ppm.
(-)-isothuyopsanone-(3): F. 38-400; [2n0 = - 1560 (cl14).
Analyse: Calculé pour C15H24O:
C 81,76 o/o H 10,98 O/o ; Trouvé : C 81,930/o H 10,87 .
Spectre U.V. (EtOH): 2020 (8 = 353,8), 2870 A (e = 23,3). Spectre RMN (Varian HA-100) : 0,64 (3H,s), 1,1 (3bd, J = 0,7 cps), 1,1 et 1,2 (2 X 3H,s), 0,2-0,6 (2H, -bande large), 1,2-1,8 (7H), 2,05-2,2 (2H,d J= 1,6 cps), 2,45-2,75 (1H, bande large) 6 ppm.
L'acétate du glycol de formule:
EMI2.2
utilisé comme produit de départ pour la préparation indiquée ci-dessus peut être préparé ainsi:
c) A un mélange en agitation contenant 3565 g de thuyopsène naturel, 10 litres de toluène et 350 g d'acétate de soude anhydre, on a ajouté, entre 18 et 35O, 4210 g d'acide peracétique à 39,5 O/o . Pendant l'addition qui a duré 5 h, on a contrôlé la température de réaction au moyen d'un bain refroidissant. On a lavé la solution de réaction jusqu'à neutralité et on l'a concentrée sous pression réduite. On a obtenu 4480 g de produit qu'on a abandonné au froid pendant la nuit. On a essoré 1880 g de l'acétate du glycol brut.
Les eaux mères, après séparation de l'acétate, ont été purifiées par fractionnement et ont fourni un mélange contenant 17,5 oxo de thuyopsanone, F. 680, et 82,5 O/o d'isothuyopsanone, F. 400.
L'acétate du glycol brut a été purifié par recristallisation dans l'éther de pétrole (50-700), F. 108-1090. Spectre RMN (CCl4) : 0,54 (3vs), 1,0 (3H,s), 1,1 (3H,s), 1,3 (3H,s), 2,0 (3H,s), 4,62 (1H,d de d, J=4 et 12cps) 6 ppm.
Process for the preparation of polycyclic carbonyl compounds
The main patent No 497360 relates to a process for the preparation of compounds of formula:
EMI1.1
which consists in oxidizing thuyopsene of formula:
EMI1.2
by a) a peracid, or b) an oxidized derivative of a transition element to directly obtain the compound
I, or c) gaseous oxygen in the presence of actinic radiation, intermediate II of formula:
EMI1.3
formed being then isomerized with an acid, to obtain I. Formula I represents a tricyclic ketone, thuyopsanone; it comprises different configurational isomers whose existence results from the presence of asymmetric centers.
It has been found that the compounds of formula I, which are particularly stable in an alkaline medium, are endowed with interesting organoieptic properties and are advantageously used in the preparation of perfumes and perfumed products.
It has now been found that if the compounds of formula:
EMI1.4
are obtained by oxidation of thuyopsene using a peracid, it is possible to operate by a process characterized in that:
a) a monoacylated glycol of formula is separated by crystallization from the reaction mixture containing the compounds of formula I already formed:
EMI1.5
in which R represents the acyl residue derived from the peracid used;
b) said solid is heated to around its boiling point to give a mixture of thuyopsanone and alcohols of formula:
EMI1.6
c) the alcohols of formula II are isomerized by means of an acidic agent to provide pure thuyopsanone.
It is also possible to use the monoacylated glycol III, obtained according to the process described under letter a), as starting material for the preparation of a compound of formula I: said glycol is then saponified into the corresponding diol which, after treatment by an acidic agent, is converted into thuyopsanone.
The following example serves to illustrate the invention in more detail. In said example, temperatures are given in degrees centigrade.
Example:
Preparation of (-) - thuyopsanone- (3)
and (-) - sothuyopsanone- (3)
a) Heating of the glycol acetate:
The glycol acetate (long), prepared according to the method described in paragraph c), was subjected to 2 successive distillations between 145 and 1600. By titration of an aliquot of the distilled product, it was found that the theoretical quantity of acid acetic has been released. The distillate was washed to neutrality and then subjected to gas chromatographic analysis which showed the existence of an approximately 1: 1 mixture of thuyopsanone (2 isomers) and alcohol of formula IIa.
EMI2.1
This mixture was used without further ado in the rest of the operations. Virtually quantitative yield.
b) Isomerization of the component of formula IIa:
The mixture of thuyopsanone and alcohol IIa (130 g) prepared according to the method described in paragraph a) was dissolved in 160 ml of alcohol. 50 ml of H2SO4 (50o / o) was added and the solution was stirred 4 hours at 400.
In the event of cloudiness, diluted with a little more alcohol. Diluted with water and extracted with petroleum ether (50-7oe). After the usual processing of the extract, 120 g of substantially pure thuyopsanone were obtained by distillation containing (-) - thuyopsanone- (3) and (-) - isothuyopsanone in an approximately 1: 1 ratio.
(-) - thuyopsanone- (3): F. 680. U.V. spectrum (EtOH): 2010A (e = 339.9), 2830 A (e = 28.5). NMR spectrum (Varian HA-100): 0.64 (3vs), 1.2 (3H, d, J = 0.7 cps), 1.1 and 1.2 (2 X 3H, s), 0.6 -0.8 (2H, broadband), 1.3-1.9 (7H), 2.1-2.3 (2H, d, J = 1.5 cps), 2.3-2.55 ( 1H, broadband) 6 ppm.
(-) - isothuyopsanone- (3): F. 38-400; [2n0 = - 1560 (c14).
Analysis: Calculated for C15H24O:
C 81.76 o / o H 10.98 O / o; Found: C 81.930 / o H 10.87.
UV Spectrum (EtOH): 2020 (8 = 353.8), 2870 A (e = 23.3). NMR spectrum (Varian HA-100): 0.64 (3H, s), 1.1 (3bd, J = 0.7 cps), 1.1 and 1.2 (2 X 3H, s), 0.2 -0.6 (2H, -brandband), 1.2-1.8 (7H), 2.05-2.2 (2H, d J = 1.6 cps), 2.45-2.75 ( 1H, broadband) 6 ppm.
Glycol acetate of formula:
EMI2.2
used as the starting material for the preparation indicated above can be prepared as follows:
c) To a stirring mixture containing 3565 g of natural thuyopsene, 10 liters of toluene and 350 g of anhydrous sodium acetate, between 18 and 35O, 4210 g of peracetic acid at 39.5 O / o were added. . During the addition, which lasted 5 h, the reaction temperature was controlled by means of a cooling bath. The reaction solution was washed until neutral and concentrated under reduced pressure. 4480 g of product were obtained which was left in the cold overnight. 1880 g of the acetate were filtered off from the crude glycol.
The mother liquors, after separation of the acetate, were purified by fractionation and gave a mixture containing 17.5 oxo of thuyopsanone, F. 680, and 82.5 O / o of isothuyopsanone, F. 400.
The crude glycol acetate was purified by recrystallization from petroleum ether (50-700), mp 108-1090. NMR spectrum (CCl4): 0.54 (3vs), 1.0 (3H, s), 1.1 (3H, s), 1.3 (3H, s), 2.0 (3H, s), 4 , 62 (1H, d of d, J = 4 and 12cps) 6 ppm.
