Description
Verfahren zur Darstellung von A4,5-Androstenol-X7-on-3. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Darstellung des bereits bekannten, als Arzneimittel verwendbaren d",-Androstenol-17-on-3, das dadurch ge kennzeichnet ist, dass man d",- Androstenol- 17-on-3 einer Behandlung unterwirft, die die Verlagerung der Kohlenstoff - Kohlenstoff Doppelbindung in die 4,5-Stellung ohne in termediäre Absättigung der Doppelbindung in 5,6-Stellung bewirkt.
Die zur Erzielung einer derartigen intra- molekularen Umlagerung geeigneten Reak tionsmittel und Reaktionsbedingungen sind unter anderem beschrieben in Houben-Weyl, Methoden der organischen Chemie, z. Band, 2. Auflage (1922), Seite 470 ff. und Seite 756 ff.
So gelingt es zum Beispiel leicht, das A"6 <B>-</B> ungesättigte Keton in das entsprechende 4"5- ungesättigte Keton umzulagern, wenn man es für kurze Zeit in saurer oder alkalischer Lösung gelinde erwärmt, etwa in Alkohol unter Zusatz von verdünnter Mineralsäure oder verdünnter Alkalilauge; bei der Auf arbeitung der Reaktionslösung erhält man dann unmittelbar in fast quantitativer Aus beute das umgelagerte d"zi - ungesättigte Keton.
Auch das Erhitzen des 4,e ungesättigten Ketons mit oder ohne Lösungsmittel auf höhere Temperaturen, z. B. auf seinen Schmelzpunkt, führt zur Isomerisierung.
Ferner können als Kontaktstoffe, fein verteilte Metalle oder Metallverbindungen, wie z. B. Nickel, Platin, Aluminiumoxyd und dergleichen für die intramolekulare Um lagerung des A",-ungesättigten Ketons in das d4,5-ungesättigte Beton verwendet werden.
<I>Beispiel:</I> 10 mg A",-Androstenol-17-on-3 werden in 2 cm' Methanol gelöst, mit 2 Tropfen 5 n-Salzsäure versetzt und mit warmem Was ser angespritzt. Es kristallisieren lange Na deln vom Schmelzpunkt 154,5 bis<B>155,5'.</B> Eine Mischprobe mit Testosteron gab keine Depression.
Das Produkt besitzt starke physiologische Wirkung und kann auch zu physiologisch wirksamen Präparaten, wie den Estern, wei terverarbeitet werden.
Method for the preparation of A4,5-androstenol-X7-one-3. The subject of the present patent is a method for the preparation of the already known, usable as a medicament d ", - androstenol-17-one-3, which is characterized in that d", - androstenol-17-one-3 is subjected to a treatment which causes the shift of the carbon-carbon double bond in the 4,5-position without in termediary saturation of the double bond in the 5,6-position.
The reac tion agents and reaction conditions suitable for achieving such an intramolecular rearrangement are described, inter alia, in Houben-Weyl, Methods of Organic Chemistry, z. Volume, 2nd edition (1922), page 470 ff. And page 756 ff.
For example, it is easy to rearrange the A "6 <B> - </B> unsaturated ketone into the corresponding 4" 5-unsaturated ketone if it is heated gently for a short time in an acidic or alkaline solution, for example in alcohol Addition of dilute mineral acid or dilute alkali lye; When the reaction solution is worked up, the rearranged d "zi-unsaturated ketone is obtained immediately in almost quantitative yield.
The heating of the 4, e unsaturated ketone with or without a solvent to higher temperatures, e.g. B. to its melting point, leads to isomerization.
Furthermore, as contact materials, finely divided metals or metal compounds, such as. B. nickel, platinum, aluminum oxide and the like for the intramolecular order of the A ", - unsaturated ketone can be used in the d4,5-unsaturated concrete.
<I> Example: </I> 10 mg of A ", - androstenol-17-one-3 are dissolved in 2 cm of methanol, 2 drops of 5N hydrochloric acid are added and warm water is sprayed on. Long needles crystallize from a melting point of 154.5 to <B> 155.5 '. </B> A mixed test with testosterone gave no depression.
The product has a strong physiological effect and can also be further processed into physiologically active preparations such as the esters.
