Description

Verfahren zur Herstellung neuer Cyclohexanole Gegenstand der vorliegenden Erfindung ist die Herstellung des 2-Cyclohexyliden- und des 2-Cyclohexyli-(3'-piperidinopropyl)-cyclohexanols der Formeln und ihrer Salze. Die neuen Verbindungen sind starke Spasmolytika und gegenüber bekannten, vergleichbaren Verbindungen besonders gegen die Parkinsonsche Krankheit wirksam. Sie können als Heilmittel Verwendung finden.Process for the preparation of new cyclohexanols The present invention relates to the preparation of 2-cyclohexylidene and 2-cyclohexyli- (3'-piperidinopropyl) -cyclohexanol of the formulas and their salts. The new compounds are strong antispasmodics and, compared to known, comparable compounds, are particularly effective against Parkinson's disease. They can be used as a remedy.

Die genannten Cyclohexanole werden erhalten, wenn man N-[i-Halogenpropyl-(3)]-piperidin mit einem Metall und hierauf mit 2-Cyclohexylidencyclohexanon oder 2-Cyclohexylcyclohexanon umsetzt und gegebenenfalls das erhaltene 2-Cyclohexyliden-i-(3'-piperidinopropyl)-cyclohexanol hydriert. Als Metall wird besonders Magnesium, ferner aber auch Kadmium oder Zink verwendet. Bei dieser Umsetzung, z. B. mit Magnesium, bildet sich die entsprechende Organometallverbindung, die hernach mit den genannten Cyclohexanonen reagiert. Vorteilhaft wird dabei das Metall aktiviert, so beispielsweise Magnesium mit Hilfe geringer Mengen Jod oder eines Alkylhalogenids.The cyclohexanols mentioned are obtained when N- [i-halopropyl- (3)] - piperidine with a metal and then with 2-cyclohexylidenecyclohexanone or 2-cyclohexylcyclohexanone converts and optionally the 2-cyclohexylidene-i- (3'-piperidinopropyl) cyclohexanol obtained hydrogenated. Magnesium is used as the metal, but also cadmium or zinc used. In this implementation, e.g. B. with magnesium, the corresponding forms Organometallic compound which then reacts with the cyclohexanones mentioned. Advantageous the metal is activated, for example magnesium with the help of lower Amounts of iodine or an alkyl halide.

Verfahrensgemäß werden Metallverbindungen der obigen Cyclohexanole erhalten, die z. B. durch Umsetzung mit Mineralsäuren in die freien Cyclohexanole übergeführt -werden. Dabei erhält man gewöhnlich Salze dieser Basen, aus denen sich in üblicher Weise die freien Basen. gewinnen lassen. Von diesen können wiederum Salze hergestellt werden, z.- B. der Halogenwasserstoffsäuren, Schwefelsäure, Salpetersäure, Phosphorsäure, Rhodanwasserstoffsäure, Essigsäure, Propionsäure, Oxalsäure, Äpfelsäure, Citronensäure, Benzoesäure, Methansulfonsäure, Äthansulfonsäure, Oxyäthansulfonsäure, Benzolsulfonsäure oder Toluolsulfonsäure.According to the process, metal compounds of the above cyclohexanols are used received, the z. B. through implementation with mineral acids in the free Cyclohexanols are transferred. This usually results in salts of these bases, from which in the usual way the free bases. to let win. Of these you can in turn salts are produced, e.g. of the hydrohalic acids, sulfuric acid, Nitric acid, phosphoric acid, hydrofluoric acid, acetic acid, propionic acid, Oxalic acid, malic acid, citric acid, benzoic acid, methanesulfonic acid, ethanesulfonic acid, Oxyethanesulfonic acid, benzenesulfonic acid or toluenesulfonic acid.

Die Erfindung wird in den nachstehenden Beispielen beschrieben. Zwischen Gewichtsteil und Volumteil besteht die gleiche Beziehung wie zwischen Gramm und Kubikzentimeter. Beispiel i 12,o Gewichtsteile Magnesium werden mit wenig absolutem Äther übergossen. Hierauf gibt man zur Einleitung der Reaktion Äthylbromid und hernach 46,8 Gewichtsteile N-[i-Chlorpropyl-(3)]-piperidin in 25 Volumteilen absolutem Benzol und 75 Volumteilen absolutem Äther unter Rühren und leichtem Erwärmen ziemlich rasch zu. Nach vierstündigem Rühren in einem Wasserbad von 50° werden in kleinen Portionen 42,8 Gewichtsteile 2-Cyclohexyhdencyclohexanon zugesetzt und das . Reaktionsgemisch noch weitere 5 Stunden bei 50° gehalten. Dann versetzt man das Reaktionsprodukt mit verdünnter Salzsäure, wobei aus der salzsauren Lösung das kristalline, schwerlösliche Hydrochlorid des 2-Cyclohexylideni-(3'-piperidinopropyl)-cyclohexanols- der Formel ausfällt. Nach dem Umkristallisieren @ aus Alkoholessigester schmilzt es bei 223 bis 225°. Durch Schütteln des Hydrochlorids mit Äther und Pottasche läBt sich die Base gewinnen, die unter 0,07 mm Druck bei 146 bis 1q.8° siedet.The invention is described in the following examples. The relationship between part by weight and part by volume is the same as that between grams and cubic centimeters. Example 12.0 parts by weight of magnesium are doused with a little absolute ether. Ethyl bromide is then added to initiate the reaction, followed by 46.8 parts by weight of N- [i-chloropropyl- (3)] piperidine in 25 parts by volume of absolute benzene and 75 parts by volume of absolute ether, with stirring and gentle heating. After four hours of stirring in a water bath at 50 ° 42.8 parts by weight of 2-Cyclohexyhdencyclohexanon are added in small portions and that. The reaction mixture was kept at 50 ° for a further 5 hours. The reaction product is then mixed with dilute hydrochloric acid, the crystalline, sparingly soluble hydrochloride of 2-cyclohexyliden- (3'-piperidinopropyl) -cyclohexanols- of the formula from the hydrochloric acid solution fails. After recrystallization @ from alcohol acetic ester, it melts at 223 to 225 °. By shaking the hydrochloride with ether and potash, the base can be obtained, which under 0.07 mm pressure boils at 146 to 1 ° 8 °.

6,4 Gewichtsteile 2-Cyclohexyliden-i-(3'-piperidinopropyl)-cyclohexanolhydrochlorid werden in 16o Volumteilen Alkohol mit 0,5 Gewichtsteil Platinoxyd und Wasserstoff geschüttelt, bis zur Aufnahme der berechneten Menge. Nach Absaugen vom Katalysator wird der Alkohol unter vermindertem Druck abdestilliert und der Rückstand mit Pottaschelösung und Äther behandelt. Aus dem Äther gewinnt man das 2-Cyclohexyl-i-(3'-piperidinopropyl)-cyclohexanol der Formel das unter 0,07 mm Druck bei 152 bis 153° siedet. Aus der Base wird mit alkoholischer Salzsäure das bei 231 bis 233° schmelzende Hydrochlorid gewonnen. Beispiel e Man arbeitet wie im Beispiel i, verwendet aber an Stelle des 2-Cyclohexylidencyclohexanons 43,o Gewichtsteile 2-Cyclohexylcyclohexanon und erhält dann direkt das 2-Cyclohexyl-i-(3'-piperidinopropyl)-cyclohexanol.6.4 parts by weight of 2-cyclohexylidene-i- (3'-piperidinopropyl) cyclohexanol hydrochloride are shaken in 160 parts by volume of alcohol with 0.5 part by weight of platinum oxide and hydrogen until the calculated amount is absorbed. After the catalyst has been filtered off with suction, the alcohol is distilled off under reduced pressure and the residue is treated with potash solution and ether. 2-Cyclohexyl-i- (3'-piperidinopropyl) -cyclohexanol of the formula is obtained from the ether that boils under 0.07 mm pressure at 152 to 153 °. The hydrochloride, which melts at 231 to 233 °, is obtained from the base with alcoholic hydrochloric acid. Example e The procedure is as in Example i, but instead of the 2-cyclohexylidenecyclohexanone, 43.0 parts by weight of 2-cyclohexylcyclohexanone are used, and 2-cyclohexyl-i- (3'-piperidinopropyl) cyclohexanol is then obtained directly.
