   Weitere Beispiele von Verbindungen der Formel I sind:   2,21-Dichloro-17a-hydroxy-D-homopregna-1,4-dien-3,11,20-    trion,   21-Chloro-17a-hydroxy-D-homopregna-1,4-dien-3,11,20-    trion,    21-Chloro-6a-fluoro-17a-hydroxy-D-homopregna-1,4-dien-

   Die Verbindungen der Formel I können erfindungsgemäss dadurch hergestellt werden, dass man in an sich bekannter Weise in einem D-Homosteroid der Formel
EMI2.2     
   worin R2, R6, R9, R17a und R21 die oben angegebenen Bedeutungen haben, die 11-Hydroxygruppe oxydiert.     



   Erwünschtenfalls wird ein erhaltenes D-Homosteroid der   Formens   
EMI3.1     
   won.n;R2,      RG,      RD    und   Rl7a    die oben genannten Bedeutungen haben: in 21-Stellung halogeniert.



     Erwünschtenfalls    wird eine 17a-Acyloxygruppe in einem   D-Homosteroid    der Formel I verseift.



     Däs:    erfindungsgemässe Verfahren der Oxydation der 11 Hydroxygruppe in einer Verbindung II kann z. B. mittels CrOs/Eisessig oder CrO3Pyridin oder Jones' Reagens vorgenommen werden.



   Die Halogenierung eines erhaltenen D-Homosteroids in 21-Stellung kann dadurch erfolgen, dass man eine solche Verbindung der Formel I, in der   R"1    Wasserstoff   ist, gewünsch-    tenfalls unter Schutz des   3-Keto-At.4-systems,    beispielsweise in Form eines 3-Enaminiumsalzes wie eines 3-Pyrrolidiniumenamins, in saurer Lösung mit elementarem Chlor, Brom oder Jod umsetzt.



   Die Verseifung einer Acyloxygruppe in einem Steroid der Formel I kann in an sich bekannter Weise z. B. mit wässrigmethanolischer Kalciumcarbonatlösung bewerkstelligt werden.



   Die Ausgangsstoffe können, soweit sie nicht bekannt oder nachstehend beschrieben sind, in Analogie zu bekannten oder in den Beispielen beschriebenen Methoden dargestellt werden.



   Verbindungen der Formel II mit einer   11a-Hydroxygrup-    pe können aus entsprechenden   11-unsubstituierten    Verbindungen mittels Mikroorganismen, die Steroide in 11a-Stellung hydroxylieren, erhalten werden.



   Die Verbindungen der Formel I sind endokrin, insbesondere anti-inflammatorisch sehr wirksam. Die hohe Wirksamkeit erscheint überraschend, nachdem bekannt war, dass das D-Homocortisonazetat nur   1/3    bis   1/2    der Hormonaktivität des Cortisonazetats aufweist (J. Am. Chem. Soc. 80, 3398).



   Die Verfahrensprodukte können als Heilmittel, z. B. in Form pharmazeutischer Präparate Verwendung finden, welche sie in Mischung mit einem für die enterale, perkutane oder parenterale Applikation geeigneten organischen oder anorganischen inerten Trägermaterial, wie z. B. Wasser, Gelatine, Gummi arabicum, Milchzucker, Stärke, Magnesiumstearat, Talk, pflanzliche Öle, Polyalkylenglykole, Vaseline usw. enthalten. Die pharmazeutischen Präparate können in fester Form, z. B. als Tabletten, Dragees, Suppositorien, Kapseln; in halbfester Form, z. B. als Salben; oder in flüssiger Form, z. B. als Lösungen, Suspensionen-oder Emulsionen, vorliegen. Gegebenenfalls sind sie sterilisiert und bzw. oder enthalten Hilfsstoffe, wie Konservierungs-, Stabilisierungs-, Netz- oder Emulgiermittel, Salze zur Veränderung des osmotischen Druckes oder Puffer.

  Sie können auch noch andere therapeutisch wertvolle Stoffe enthalten.



   Als Richtlinie für den Dosierbereich topischer Präparate kann etwa 0,01-1   O/o,    bei systemischen Präparaten etwa 0,1 bis 10 mg pro Applikationseinheit gelten.



   Die Herstellung der Arzneimittel kann in an sich bekannter Weise erfolgen, indem man die Verbindungen der Formel   1    mit zur therapeutischen Verabreichung geeigneten, nichttoxischen, an sich in solchen Präparaten üblichen festen und/ oder flüssigen Trägermaterialien, wie z. B. den vorstehend genannten, vermischt und gegebenenfalls in die gewünschte Form bringt.



   In den folgenden Beispielen sind die Temperaturen in Celsiusgraden angegeben.

Das Gemisch wird 40 Minuten bei Raumtemperatur unter Argon stehengelassen. Nach Zugabe von 5 ml MeOH wird die Lösung im Vakuum eingeengt, mit Methylenchlorid extrahiert, mit Wasser und verdünnter Kochsalzlösung gewaschen, getrocknet und eingedampft.
