Norpatchoulenol ist eine bekannte Verbindung, die beispielsweise in der französischen Patentpublikation Nummer 2 151 522 beschrieben ist. Norpatchoulenol ist eine sehr wichtige Riechstoffkomponente von Patchouli-Oel, in welchem es in sehr viel geringern Eonzen-Norpatchoulenol is a well-known compound, for example in the French patent publication Number 2 151 522 is described. Norpatchoulenol is a very important fragrance component of patchouli oil, in which there is much less concentration of

The ratio of the "two alcohols" is approximately 1: 100.
Das erfindungsgemässe Verfahren zur Herstellung von Norpatchoulenol (Formel I) ist dadurch gekennzeichnet, dass man die Säure der FormelThe inventive method for the production of Norpatchoulenol (formula I) is characterized in that one has the acid of the formula

Die oxidative. Decarboxylierung kann "beispielsweise mit Bleitetraacetat durchgeführt werden, wobei inerte organische oder polare koordinierende Lösungsmittel verwendet werden können, wie z.B. Benzol, Chlorbenzol, Chloroform, Dimethylformamid, Tetrahydrofuran, Acetonitril, Dioxan, Dimethylsulfoxid oder Pyridin. Die Reaktionsgeschwindigkeit hängt vom Lösungsmittel und von der Temperatur ab. Im allgemeinen wird man bestrebt sein, bei möglichst tiefen Temperaturen zu arbeiten, da damit Nebenreaktionen vermieden werden können. Die Temperatur kann aber im übrigen zwischen Raumtemperatur oder sogar darunter und der Rückflusstemperatur des Reaktionsgemisches liegen.The oxidative. Decarboxylation can be carried out, for example, with lead tetraacetate, with inert organic or polar coordinating solvents can be used, such as benzene, chlorobenzene, chloroform, Dimethylformamide, tetrahydrofuran, acetonitrile, dioxane, dimethyl sulfoxide or pyridine. The speed of response depends on the solvent and the temperature. In general one will strive for as deep as possible Temperatures to work, since side reactions can be avoided. The temperature can, however, between Room temperature or even below and the reflux temperature of the reaction mixture.
Vorzugsweise verwendet man für die erfindungsgemässe Reaktion Kupfer(II)acetat als Katalysator. Die Reaktion wird auch durch Basen, wie z.B. Pyridin, sowie durch Salze wie Lithiumacetat, katalysiert.Preference is given to using copper (II) acetate as catalyst for the reaction according to the invention.

Zu einer Lösung von 500 mg der Säure II, 200 mg Kupfer(II)-acetat und 1 ml Pyridin in 50 ml Benzol gi"bt man 800 mg Bleitetraacetat und erhitzt dann das Gemisch 30 Minuten zum Rückfluss. Nach dem Abkühlen fügt man 1,2-Propandiol zu und extrahiert mit Aethyläther. Die Verdampfung des Lösungsmittels ergibt ein OeI, das an SiOp ehromat ographiert wird. Man erhält so 300 mg eines Produktes, das auf Grund der dünnschichtchromatographischen, IE- und NMR-Analyse mit natürlichem Norpatchoulenol identisch ist.To a solution of 500 mg of acid II, 200 mg of copper (II) acetate and 1 ml of pyridine in 50 ml of benzene 800 mg of lead tetraacetate are added and the mixture is then refluxed for 30 minutes. After cooling 1,2-propanediol is added and the mixture is extracted with ethyl ether. Evaporation of the solvent gives an oil which is ographed on SiOp ehromat. You get 300 mg of a product that, due to the thin-layer chromatographic, IE and NMR analysis with natural norpatchoulenol is identical.
Die Säure II kann wie folgt erhalten werden:The acid II can be obtained as follows:
36 Stunden vor der Verabreichung von Patchoulol werden Kaninchen in Metabolismus-Käfige verbracht und dort 24 Stunden nüchtern gehalten. Dann erhält jedes Kaninchen (Albino, ca. 3 kg) 1 g Patchoulol (oder 1,5 bzw. 2 g je nach dem Versuch) als Suspension in 20 ml einer 1^-igen Carboxymethylcellulose-Lösung, anschliessend 25 ml Wasser. Die Verabreichung erfolgt am mit Nembutal (30 mg/kg) anästhesierten Tier. Nachher kann das Tier nach Belieben V/asser und Nahrung aufnehmen. Der Urin wird alle 24 Stunden gesammelt.36 hours before patchoulol administration rabbits are placed in metabolism cages and fasted there for 24 hours. Then each rabbit receives (Albino, approx. 3 kg) 1 g patchoulol (or 1.5 or 2 g depending on the experiment) as a suspension in 20 ml of a 1 ^ -igen Carboxymethyl cellulose solution, then 25 ml of water. The administration is carried out on the animal anesthetized with Nembutal (30 mg / kg). Afterwards the animal can eat and drink at will Ingesting food. The urine is collected every 24 hours.
Der während 26 Stunden gesammelte urin wird mit lOfo-lgev Salzsäure auf ein pH von 4,5 angesäuert. Dann fügt man 6 ml (ß-D-Glucuronid)-glucuronidase (Sue d'Helix Pomatia de I1Industrie Biologique Francaise) zu, lässt 24 Stunden bei 370C stehen und säuert dann auf pH = 1 an. Nach Sättigung mit NaCl wird die Lösung mit Aethylather extrahiert.The urine collected over the course of 26 hours is acidified to a pH of 4.5 with 10fo-lgev hydrochloric acid. Then 6 ml (β-D-glucuronide) -glucuronidase (Sue d'Helix Pomatia de I 1 Industrie Biologique Francaise) are added, left to stand at 37 ° C. for 24 hours and then acidified to pH = 1. After saturation with NaCl, the solution is extracted with ethyl ether.

3 g Chromsäureanhydrid/Pyridin-Komplex werden in 50 ml Methylenchlorid, enthaltend 6 Tropfen Pyridin, gelöst. Man fügt dann die lösung von 460 mg des Glykols IV in 10 ml Methylenchlorid zu und rührt 4 Stunden bei Raumtemperatur. Das Reaktionsgemiseh wird filtriert und der Niederschlag mit 50 ml Methylenchlorid gewaschen. Die vereinigten Filtrate werden gewaschen;4 mal mit je 10 ml einer 5^-igen wässerigen Sodalösung, 3 mal mit je 10 ml einer 10?&-igen Salzsäurelösung, 2 mal mit je 10 ml einer gesättigten wässerigen Natriumbicarbonatlösung und schliesslich 2 mal mit je 10 ml Wasser. Die organische Lösung wird über Natriumsulfat getrocknet, dann filtriert. Nach Destillation des Lösungsmittels erhält man 465 mg des Aldehyds V, der sich durch Chromatographie an einer SiOp-Kolonne reinigen lässt. Der gereinigte Aldehyd V kann durch folgende Daten charakterisiert werden:3 g of chromic anhydride / pyridine complex are dissolved in 50 ml of methylene chloride containing 6 drops of pyridine. The solution of 460 mg of glycol IV in 10 ml of methylene chloride is then added and the mixture is stirred for 4 hours at room temperature. The reaction mixture is filtered and the precipitate is washed with 50 ml of methylene chloride. The combined filtrates are washed; 4 times with 10 ml each of a 5 ^ aqueous Soda solution, 3 times with 10 ml each of a 10% hydrochloric acid solution, 2 times with 10 ml each of a saturated aqueous sodium bicarbonate solution and finally 2 times with 10 ml each Water. The organic solution is dried over sodium sulfate, then filtered. After distillation of the solvent 465 mg of aldehyde V are obtained, which is determined by chromatography can be cleaned on a SiOp column. The cleaned one Aldehyde V can be characterized by the following data:

Zu einer Lösung von 440 mg Silbernitrat in 1 ml Wasser gibt man unter Rühren eine Lösung von 200 mg Natriumhydroxid in 1 ml Wasser, dann die Lösung von I46 mg des Aldehyds Y in 0,5 ml Pentan. Man rührt 30 Minuten bei Raumtemperatur und erwärmt dann während 2 Stunden. Nach dem Abkühlen filtriert man und wäscht den Niederschlag mit 10 ml warmem Wasser. Die vereinigten Eiltrate werden 2 mal mit je 5 ml Aethylather von 220B angesäuert. Man fügt Natriumchlorid bis zur Sättigung der Lösung zu und extrahiert 3 mal mit je 10 ml Aethyläther.To a solution of 440 mg of silver nitrate in 1 ml of water, a solution of 200 mg of sodium hydroxide in 1 ml of water is added with stirring, then the solution of 146 mg of aldehyde Y in 0.5 ml of pentane. The mixture is stirred for 30 minutes at room temperature and then heated for 2 hours. After cooling, it is filtered and the precipitate is washed with 10 ml of warm water. The combined Eiltrate are acidified twice with 5 ml of ethyl ether of 22 0 B twice. Sodium chloride is added until the solution is saturated and it is extracted 3 times with 10 ml of ethyl ether each time.

Die vereinigten Aetherphasen werden mit gesättigter ITatriumchloridlösung gewaschen und dann über Natriumsulfat getrocknet. Fach Filtration wird das Lösungsmittel abdestilliert, Man erhält 110 mg der Säure II mit folgenden charakteristischen physiko-chemiechen Konstanten:The combined ether phases are washed with saturated sodium chloride solution and then over sodium sulfate dried. Subject filtration, the solvent is distilled off. 110 mg of acid II are obtained with the following characteristics physico-chemical constants:
