Description
Verfahren zur Herstellung von 4-Halogen-3-keto-d 4-steroiden In der Hauptpatentschrift wird ein Verfahren be schrieben und beansprucht zur Herstellung von in 4- Stellung substituierten Steroidverbindungen der For mel I
EMI0001.0007
worin R (H)OH, (H)OCOCH3, O, (H)COCH3, (H)COCH20H, (H)COCH20COCH3 oder (OH)COCH20COCH3, R' H2, (H)OH oder O, und R" OH, Br,
Cl oder F bedeuten.
Bei diesem Verfahren wird ein 4,5-Epoxy-3-keto- steroid der Formel
EMI0001.0019
in einem organischen Lösungsmittel mit Mineralsäuren behandelt.
Nach dem besagten Verfahren können auch neue Steroidderivate der Formel I, die eine starke anabole Wirkung mit einer geringen androgenen Wirkung auf weisen, hergestellt werden, wobei jedoch als Aus gangsstoffe nur die ss-Formen der 4,5-Epoxyde ver wendet werden können.
Es wurde nun gefunden, dass die Steroide der Formel I, worin R (H)OH, (H)OR"', O, (CH3)OH, R' H2, (H)OH, O, R" Cl, F und R"' einen Acylrest bedeuten, auch aus der a-Form oder einer Mischung der a- und ss-Form der 4,5-Epoxyde hergestellt wer den können, wenn man diese in einem inerten orga nischen Lösungsmittel,
vorzugsweise in reinem Chloroform oder in Äthanol enthaltendem Chloro- form, mit wasserfreiem Chlorwasserstoff oder Pyri- diniumchlorid zu einem 4 -Chlor - 3 - keto - 44 - steroid oder mit wasserfreiem Fluorwasserstoff zu einem 4-Fluor-3-keto-44-steroid umsetzt.
Es ist demgemäss mit Hilfe des vorliegenden er findungsgemässen Verfahrens möglich, die 4-Chlor- und 4-Fluor-Steroide direkt aus dem Gemisch der 4,5,B- und 4,5a-Epoxyde herzustellen, das man durch Behandeln der 3-Keto-44-steroide mit alkalischem Wasserstoffsuperoxyd erhält, wobei man, neben der Vereinfachung des Verfahrens, eine beträchtliche Er höhung der Ausbeuten erzielt.
Die erfindungsgemäss- hergestellten Verbindun gen zeigen eine starke anabole Wirkung auf die Pro- teinsynthese, aber keine wesentliche androgene Wir kung, während die beiden genannten Wirkungen bei den bisher in der Therapie verwendeten Steroiden stets mit gleicher Intensität auftreten.
Es ist nunmehr möglich, von der anabolen Wir kung Gebrauch zu machen, ohne dass gleichzeitig die sexuelle Aktivität angeregt wird, was sehr wertvoll ist für die Behandlung von Schwächezuständen, Osteoporose, Magerkeit, Rekonvaleszenten, Früh geburten, Unterentwicklung und Senilität. Die erfindungsgemässen neuen Produkte zeigen auch die anderen Eigenschaften der bisher verwen deten Anabolika, indem sie verwendbar sind zur Behandlung von Mammacarcinom, gewissen Funk tionsstörungen der Ovarien usw.
<I>Beispiel 1</I> 4-Chlor-testosteron
EMI0002.0005
15 g eines in 375 ml Chloroform gelösten Ge misches von 4f,5-Epoxy-ätiocholan-17/1-ol-3-on und 4a,5-Epoxy-androstan-17f-ol-3-on wird während etwa 2 Stunden bei Zimmertemperatur mit einem Strom von gasförmigem HCI behandelt.
Die Chloroformlösung wird mit Natriumbicar- bonatlösung und Wasser gewaschen, getrocknet und das Lösungsmittel abdestilliert.
Der Rückstand wird aus Benzol oder wässrigem Methanol kristallisiert, wobei man 9 g nadelförmiger Kristalle vom Schmelzpunkt 186-188 C erhält. Aus der Mutterlösung erhält man weitere 3,2 g eines bei 180-184 C schmelzenden Produktes. A",ax 256 m,u, e <I>=</I> 13160.
Zum gleichen Ergebnis gelangt man, wenn man anstelle von Chloroform Methylenchlorid, welches 3 ö Methanol enthält, verwendet bzw. wenn die Sättigung mit gasförmigem HCl während 2 Stunden bei -8 C erfolgt.
<I>Beispiel 2</I> 4-Chlor-testosteron-acetat 2g 4a,5-Epoxyandrostan-17ss-ol-3-on-acetat, Schmelzpunkt 170-172 C, gelöst in 50 ml wasser freiem Chloroform, werden während 2 Stunden bei Zimmertemperatur mit wasserfreiem HCt behandelt, wobei die Lösung ohne weiteres Dunkeln blassgelb wird. Sie wird dann neutral gewaschen und einge dampft. Der Rückstand wird aus Methanol umkri stallisiert, wobei man 1,5 g 4-Chlor-testosteron-acetat, Schmelzpunkt 226-228 C, erhält.
<I>Beispiel 3</I> 4-Chlor-testosteron-acetat 1 g 4a,5-Epoxy-androstan-17f-ol-3-on-acetat wird mit 15 ml einer 1,2-n-Lösung von Pyridiniumchlorid in Chloroform während 8 Stunden zum Sieden er hitzt.
Die entstehende Lösung wird mit verdünnter Salzsäure, verdünnter Natriumbicarbonatlösung und Wasser gewaschen und schliesslich eingedampft. Man erhält 4-Chlor-testosteron-acetat <B>in</B> beinahe quanti tativer Ausbeute. <I>Beispiel 4</I> 4-Chlor-1 7a-tnetlzyl-testosteroii

Nach 15minutenlangem Stehen wird die Lösung mit Wasser gewaschen, getrocknet und das Lösungsmittel abdestilliert. Der Rückstand wird durch Chromato- graphieren an 90 g Florisil fraktioniert, wobei die ein zelnen Fraktionen mit Äther eluiert und aus Äther umkristallisiert werden. Man erhält 2,2 g 4-Chlor- 17a-methyl-testosteron, Schmelzpunkt 148-150" C, 256 m < i., e = 14000.
<I>Beispiel 5</I> 4-Chlor-adrenosteron

Hierauf fügt man 2-n- Natronlauge zu, bis die Lösung schwach sauer rea- giert.
Der Niederschlag wird abgetrennt, mit Wasser gewaschen und getrocknet, worauf man das Lösungs mittel abdestilliert. Durch Umkristallisieren aus Äther erhält man 190 mg 4-Fluor-testosteronacetat, Schmelz punkt 178-180 C, A",ax = 241 my, E <I>=</I> 11670.

Process for the preparation of 4-halo-3-keto-d 4-steroids In the main patent specification a process is described and claimed for the preparation of steroid compounds of the formula I substituted in the 4-position
EMI0001.0007
where R (H) OH, (H) OCOCH3, O, (H) COCH3, (H) COCH20H, (H) COCH20COCH3 or (OH) COCH20COCH3, R 'H2, (H) OH or O, and R "OH, Br,
Cl or F mean.
In this process, a 4,5-epoxy-3-keto steroid of the formula
EMI0001.0019
treated in an organic solvent with mineral acids.
According to the said process, new steroid derivatives of the formula I, which have a strong anabolic effect with a low androgenic effect, can be prepared, but only the ss forms of 4,5-epoxides can be used as starting materials.
It has now been found that the steroids of the formula I, wherein R (H) OH, (H) OR "', O, (CH3) OH, R' H2, (H) OH, O, R" Cl, F and R "'mean an acyl radical, also from the a-form or a mixture of the a- and ss-form of the 4,5-epoxides who can, if they are in an inert organic solvent,
preferably in pure chloroform or in chloroform containing ethanol, with anhydrous hydrogen chloride or pyridinium chloride to form a 4-chloro-3-keto-44-steroid or with anhydrous hydrogen fluoride to form a 4-fluoro-3-keto-44-steroid .
It is accordingly possible with the help of the present inventive method to prepare the 4-chloro and 4-fluoro steroids directly from the mixture of 4,5, B- and 4,5a-epoxides, which is obtained by treating the 3-keto -44-steroids obtained with alkaline hydrogen peroxide, which, in addition to simplifying the process, achieved a considerable increase in yields.
The compounds produced according to the invention show a strong anabolic effect on protein synthesis, but no significant androgenic effect, while the two mentioned effects always occur with the same intensity with the steroids previously used in therapy.
It is now possible to use the anabolic effect without stimulating sexual activity at the same time, which is very valuable for the treatment of weaknesses, osteoporosis, leanness, convalescents, premature births, underdevelopment and senility. The new products according to the invention also show the other properties of the previously used anabolic steroids in that they can be used for the treatment of breast cancer, certain functional disorders of the ovaries, etc.

0.2 g of a mixture of 4 / 3,5-epoxy-etio-cholan-3,11,17-trione and 4a, 5-epoxy-androstan-3,11,17-trione (obtained by epoxidizing 0.2 g of adrenosterone with H, 0., and NaOH) are dissolved in 15 ml of chloroform and 1.5 ml of ethanol and treated with anhydrous HCl for 30 minutes. The solution is then worked up in the usual way and the residue is recrystallized from ether.
90 mg of 4-chloro-adrenosterone, melting point 175-177 C, i ", a, = 255 m, ci., E <I> - </I> 11630 are obtained.
<I> Example 6 </I> 4-Flcior-testosterone-acetate
EMI0002.0070
Dissolve 1 g of a mixture of 4ss, 5-epoxy-ätiocholan-17ss-ol-3-on-acetate and 4a, 5-epoxy-androstane-17ss-ol-3-on-acetate in 30 ml of chloroform and 30 ml of absolute ethanol and treated with anhydrous HF for 1 hour. 2N sodium hydroxide solution is then added until the solution reacts slightly acidic.
The precipitate is separated off, washed with water and dried, whereupon the solvent is distilled off. Recrystallization from ether gives 190 mg of 4-fluoro-testosterone acetate, melting point 178-180 C, A ", ax = 241 my, E <I> = </I> 11670.
<I> Example 7 </I> 4-fluoro testosterone propionate
EMI0003.0014
Using the same procedure as in Example 6, starting from a mixture of 4ss, 5-epoxy-ätiocholan-17ss-ol-3-one-propionate and 4a, 5-epoxy-androstane-17ss-ol-3-one-propionate , which after recrystallization from petroleum ether shows a melting point of 128-130 C, A ", a @ = 243 my, e <I> = </I> 12 300.
The products that can be produced by the process according to the invention show the following pharmacological action: 4-chloro-testosterone propionate increases the weight of M. levator ani from 5 to 27 mg; 4-chloro-testosterone from 5 to 19 mg; the 4-chloro-17a-methyl-testosterone from 9.8 to 24.5 mg; the 4-fluoro testosterone propionate from 7.9 to 20 mg.
The 4-chloro testosterone propionate increases the weight of the prostate from 6.7 to 43 mg (ratio of anabolic to androgenic effects = 0.61); the 4-chloro-testosterone from 6.7 to 31.5 mg (the ratio given above is 0.57); the 4-chloro-17a-methyl-testosterone from 4.2 to 48.7 mg (the ratio given above is 0.35); the 4-fluoro-testosterone propionate from 5.2 to 39.2 mg (the ratio given above is 0.35).
