Description

Verfahren zur Darstellung von Aminen der Cyclopentanopolyhydrophenanthrenreihe Es wurde gefunden, daß man zu Aminen der Cyclopentanopolyhydrophenanthrenreihe in einfacher Weise dadurch gelangen kann, daß man solche Cyclopentanopolyhydrophenanthrenverbindungen, welche an dem fünfgliedrigen Ring eine-CO-CH,- Gruppe tragen, dem Abbau nach Beckmann unterwirft. Verfahrensgemäß behandelt man die Oxime der genannten Ketone mit umlagernden Mitteln, wie PCI., SOCI. usw. Da sich die Umlagerung bei den genannten Körpern mit außerordentlicher Leichtigkeit vollzieht, können die Amine in hoher Ausbeute und Reinheit erhalten werden. Beispiele i. i,3g Acetylpregnenolonoxim (Zersetzungspunkt um 1972) werden in io ccm Benzol mit 3,2g Thionylchlorid versetzt, wobei eine heftige Reaktion einsetzt und die Farbe der Lösung nach rot umschlägt. Die Lösung wird noch 2 Stunden unter Rückfluß erhitzt, danach im Vakuum eingeengt und der Rückstand in 135 ccm 96prozentigem Alkohol mit 3o ccm halbkonzentrierter Salzsäure 18 Stunden erhitzt. Darauf wird wieder eingeengt und nach Hinzufügen von Wasser ausgeäthert. Die wäßrige Lösung enthält das 3-Oxy-i7-aminoandrostenhydrochlorid; nach Zugabe von Natronlauge flockt das Amin aus. Die Mischung wird ausgeäthert und die ätherische Lösung getrocknet. Das Amin läßt sich aus Petroläther umlösen. Schmelzpunkt i64 bis z66,5" (unkorr.). Es enthält noch bis 1/2 Mol Kristallwasser. Aus ätherischer Lösung läßt es sich als Acetat fällen, Zersetzungspunkt 227,5'. Process for the preparation of amines of the cyclopentanopolyhydrophenanthrene series It has been found that amines of the cyclopentanopolyhydrophenanthrene series can be obtained in a simple manner by subjecting such cyclopentanopolyhydrophenanthrene compounds which have a -CO-CH, group on the five-membered ring to the Beckmann degradation. According to the method, the oximes of the ketones mentioned are treated with rearrangement agents, such as PCI., SOCI. etc. Since the rearrangement of the bodies mentioned takes place with extraordinary ease, the amines can be obtained in high yield and purity. Examples i. 1.3 g of acetylpregnenolone oxime (decomposition point around 1972) are mixed with 3.2 g of thionyl chloride in 10 cc of benzene, a vigorous reaction commencing and the color of the solution turning red. The solution is refluxed for a further 2 hours, then concentrated in vacuo and the residue is heated in 135 cc of 96 percent alcohol with 30 cc of half-concentrated hydrochloric acid for 18 hours. It is then concentrated again and, after adding water, is extracted with ether. The aqueous solution contains 3-oxy-i7-aminoandrostene hydrochloride; after adding sodium hydroxide solution, the amine flocculates. The mixture is extracted with ether and the ethereal solution is dried. The amine can be dissolved in petroleum ether. Melting point 164 to 66.5 "(uncorr.). It still contains up to 1/2 mole of water of crystallization. It can be precipitated as acetate from an ethereal solution, decomposition point 227.5 '.

3,9 g Acetylpregnenolonoxim werden in 30 ccm Benzol mit 9,6- Thionylchlorid 2 Stunden behandelt und der Rückstand der Reaktionslösung, wie oben beschrieben, mit 405 ccm 96prozentigem Alkohol und goccm halbkonzentrierter Salzsäure 18 Stunden hydrolysiert. Ausbeute an 3-Oxy-=7-aminoandrosten-A 5, 6-acetat 1,25 g.3.9 g of acetylpregnenolone oxime are treated with 9,6-thionyl chloride in 30 cc of benzene for 2 hours and the residue of the reaction solution is hydrolyzed, as described above, with 405 cc of 96 percent alcohol and half-concentrated hydrochloric acid for 18 hours. Yield of 3-oxy- = 7-aminoandrosten-A 5, 6-acetate 1.25 g.

6 g Acetylpregnenolonoxim werden mit 14,5 g Thionylchlorid und 45 ccm Benzol behandelt und der Rückstand in 61o ccm 96prozentigem Alkohol mit 13q. ccm halbkonzentrierter Salzsäurehydrolysiert. Ausbeutean3-Oxy-i7-aminoandrosten-A 5, 6-acetat i,92 g.6 g of acetylpregnenolone oxime with 14.5 g of thionyl chloride and 45 ccm benzene treated and the residue in 61o ccm 96 per cent alcohol with 13q. ccm of semi-concentrated hydrochloric acid hydrolyzed. Yield of 3-oxy-17-aminoandrosten-A 5, 6-acetate i, 92 g.

2. 3,1 g des Oxims von 3 .@cetylpregnanolon (Nadeln F. i13 °) «erden mit 5o ccm Benzol und iog Thionylchlorid 3 Stunden unter Rückfluß zum Sieden erhitzt. Nach dem Abdestillieren löst man den Rückstand in 3o ccm Benzol und 25o ccm 96prozentigem Äthanol auf und kocht nach Zusatz von 31 ccm konzentrierter Salzsäure und 31 ccm Wasser 18 Stunden lang unter Rückfluß. Man engt ein, gießt in verdünnte Natronlauge und äthert aus. Die Ätherlösung reagiert nach dem Waschen alkalisch. Die Ätherlösung wird mit Natriumsulfat getrocknet und eingeengt. Beim vorsichtigen Neutralisieren mit ätherischer Eisessiglösung kristallisiert das Aminacetat aus und kann abgesaugt werden. Das Aminacetat wird an der Luft klebrig und löst sich leicht in Wasser auf. Man löst in Methanol, gibt etwas Sodalösung und Wasser zu; nachdem Trübung -eingetreten ist, kristallisiert bald das freie Amin in langen feinen Nadeln aus. Durch Kochen mit etwas Tierkohle und nochmaliges Umlösen aus Methanol wird die Substanz rein erhalten. Schmelzpunkt 17q.°.2. 3.1 g of the oxime of 3. @ Cetylpregnanolone (needles at 13 °) "ground heated to boiling under reflux for 3 hours with 50 cc benzene and iog thionyl chloride. After distilling off, the residue is dissolved in 30 cc benzene and 25o cc 96 percent Ethanol and boils after the addition of 31 cc of concentrated hydrochloric acid and 31 cc Reflux water for 18 hours. It is concentrated and poured into dilute sodium hydroxide solution and ether out. The ether solution reacts alkaline after washing. The ethereal solution is dried with sodium sulfate and concentrated. When neutralizing carefully With an ethereal glacial acetic acid solution, the amine acetate crystallizes out and can be filtered off with suction will. The amine acetate becomes sticky in air and easily dissolves in water. Dissolve in methanol, add some soda solution and water; after turbidity has occurred is, the free amine soon crystallizes out in long fine needles. By cooking with a little animal charcoal and redissolving it from methanol, the substance becomes pure obtain. Melting point 17q. °.

Die nach-dem Verfahren gewinnbaren Amine lassen sich durch Oxydation nach an sich bekannten Methoden, z. B. über die Alkohole, in die zugehörigen Betone überführen.The amines which can be obtained by the process can be oxidized according to methods known per se, for. B. via the alcohols, in the associated concretes convict.
