Definitions
- the present invention relates to a new process for the preparation of 14,17 ⁇ -etheno- and 14,17 ⁇ -ethano-16 ⁇ , 17ß-steroid diols and their derivatives of the general formula I,
- ST for the rest (ABC rings) of a steroid molecule AB for a CC double or CC single bond
- Halogen atoms F, Cl, Br
- the DIELS-ALDER addition of ⁇ -acetoxyacrylonitrile to 1 yields the ethenonitrile 2, which after conversion into the 16-ketone 3 with sodium in liquid ammonia stereoselectively gives the ethenotriol 4.
- the desired ethanotriol 5 is obtained by catalytic hydrogenation of the etheno double bond.
- a disadvantage of this synthesis is the use of the highly toxic and expensive ⁇ -acetoxyacrylonitrile, a second in the complex method for reducing the ketone 3 with sodium in ammonia.
- the 14,17 ⁇ -etheno bridge in the compounds la is hydrogenated if desired, the ester groups present are saponified if desired, and then the free hydroxyl groups are then partially and / or successively or completely with a straight or branched chain alkanoyl chloride or bromide or a corresponding one if desired esterified the alkane carboxylic anhydride with 1 or 4 to 10 carbon atoms or with benzoyl chloride.
- an estratriene derivative which is optionally substituted in the A, B and / or C ring is preferably reacted according to the invention.
- a compound of the general formula II to be used preferably has in the 3-position a straight-chain or branched-chain alkanoyloxy radical having 1 or 4 to 10 carbon atoms, in particular the acetyloxy radical, or in the 3-position a saturated or unsaturated one , straight-chain hydrocarbonoxy radical with 1 or 2 to 10 carbon atoms or branched-chain hydrocarbonoxy radical with 3 to 10 carbon atoms, in particular the methoxy radical.
- the substituent R "on the oxygen atom of the C-17 atom represents a straight-chain, saturated alkanoyl radical having 2 to 5 carbon atoms, in particular the acetyl radical.
- 3,17-Diacetoxy-estra-l, 3,5 (10), 14,16-pentaen and 17-acetoxy-3-methoxy-estra-l are very particularly suitable as compounds of the general formula ⁇ for the new process , 3.5 (10), 14.16-pentaen.
- vinyl esters with a straight-chain or branched-chain saturated alkanoyl radical with 1 or 4 to 20 carbon atoms or vinyl benzoate are suitable, the alkanoyl radical or the benzoyl radical with one or more halogen atoms (F, Cl , Br) can be substituted.
- vinyl esters of the general formula m The following, practically non-toxic and commercially available vinyl esters may preferably be mentioned as vinyl esters of the general formula m:
- the vinyl acetate (vinyl acetate) is particularly noteworthy, since it is manufactured on an industrial scale and is therefore extremely inexpensive to obtain (approx. 10 DM / 1).
- the vinyl ester of the general formula DI is reacted as dienophu in a cycloaddition with the diene of the general formula D (DiELS-ALDER reaction).
- DI dienophu
- D diene of the general formula D
- the reaction of 3,17-di-acetoxy-estra-1,3,5 (10), 14,16-pentaen (1) with vinyl acetate is given as an example in the scheme below.
- the ethenotriol triacetate 6 can thus be obtained directly; a complex step such as the difficult reaction of the 16-ketone 3 with sodium in liquid ammonia is eliminated.
- the triol 5 can be obtained by catalytic hydrogenation to ethanotriol triacetate 7 and its saponification.
- Compounds 6 and 7, like triol 5, are compounds of general formula I.
- Compounds 5, 6 and 7 (or their analogous compounds if another compound of general formula D was used as compound 1 or a vinyl ester other than vinyl acetate ) can be converted into other compounds of the general formula I by conventional organic chemistry processes.
- the 3-, 16- and 17-alkanoyloxy or hydroxy groups have different reactivities.
- the compound of the general formula D has an alkanoyloxy radical or a hydrocarbonoxy radical in the 3-position, the 3-hydroxy group is released by saponification or ether cleavage with a LEWIS acid using conventional methods, and the esterification or etherification thereof to other compounds of the general formula I leads.
- the cycloaddition is carried out at higher temperatures in order to improve the reactivity of the vinyl ester component.
- a high-boiling solvent such as. As mesitylene, xylene or toluene, preferably under pressure, which sets itself in the closed reaction vessel.
- the typical reaction conditions for the addition of vinyl acetate (boiling point: 72-73 ° C.) to 3,17-diacetoxy-estra-1,3,5 (10), 14,16-pentaen (1) are given here as an example :
- Reaction temperature 180 - 200 ° C
- pressure approx. 8 - 10 bar.
- the yield of the DiELS-ALDER adduct 6, which forms stereo- and regioselectively under these conditions, is approximately 50% of theory.
- a solution of 25.0 g of 3,17-diacetoxy-estra-l, 3,5 (10), 14,16-pentaen in 75 ml of vinyl acetate is in a pressure vessel in an oil bath for 3 days at 190 ° C and 2 days at 215 ° C heated.
- the reaction mixture is evaporated in vacuo.
- the residue, 45.1 g of oily product, is chromatographed on silica gel: (diameter of the column 7 cm, filling height 35 cm, particle size 0.015-0.04 mm).
- a suspension of 1.0 g of 17-acetoxy-3-methoxy-estra-l, 3.5 (10), 14.16-pentaen in 1 ml of xylene is mixed with 2 ml of vinyl acetate and in a pressure vessel in an oil bath at 190 ° for 11 days C. heated. The reaction mixture is evaporated in vacuo. The residue, 2.10 g of oily product, is chromatographed on silica gel (diameter of the column 4.5 cm, filling height 20 cm, particle size 0.015-0.04 mm).
- a solution of 2.9 g of 3,16 ⁇ , 17ß-triacetoxy-14,17 ⁇ -ethano-estra-l, 3,5 (10) -triene in 30 ml of methanol is mixed with 8.5 ml of 2N sodium hydroxide solution and 60 min at 60 ° C. touched.
- the reaction mixture is then neutralized with 17 ml of 1N hydrochloric acid, mixed with 15 ml of deionized water and stirred for 15 minutes.
- the crystallized product is washed with water and dried.
- the yield is 2.06 g of 14,17 ⁇ -ethano-estra-l, 3,5 (10) -trien-3.16 ⁇ , 17ß-triol. Melting point 324 ° C.

Bei den beschriebenen Verbindungen handelt es sich um wertvolle pharmazeuti¬ sche Wirkstoffe. Sie stellen hochaktive, oral wirksame Estrogene dar. Besonderes Interesse besitzt die Verbindung 14,17α-Ethano-estra-l,3,5(10):trien-3,16α,17ß-triol (5). Diese wird bisher gemäß nachfolgender Syntheseroute ausgehend von dem Pentaendiacetat 1, erhalten:

Die DIELS-ALDER- Addition von α-Acetoxyacrylnitril an 1 liefert das Ethenonitril 2, das nach der Überführung in das 16-Keton 3 mit Natrium in flüssigem Ammoniak stereoselektiv das Ethenotriol 4 ergibt. Durch katalytische Hydrierung der Etheno-Doppelbindung erhält man das gewünschte Ethanotriol 5.The DIELS-ALDER addition of α-acetoxyacrylonitrile to 1 yields the ethenonitrile 2, which after conversion into the 16-ketone 3 with sodium in liquid ammonia stereoselectively gives the ethenotriol 4. The desired ethanotriol 5 is obtained by catalytic hydrogenation of the etheno double bond.
Ein Nachteil dieser Synthese besteht in der Verwendung des hochgiftigen und teuren α-Acetoxyacrylnitrils, ein zweiter in der aufwendigen Methode zur Reduktion des Ketons 3 mit Natrium in Ammoniak.A disadvantage of this synthesis is the use of the highly toxic and expensive α-acetoxyacrylonitrile, a second in the complex method for reducing the ketone 3 with sodium in ammonia.

worin ST" für den Rest (A-B-C-Ringe) eines Steroidmoleküls sowie R" für einen gerad- oder verzweigtkettigen, gesättigten Alkanoylrest oder für den Benzoylrest stehen, mit einem Vinylester der allgemeinen Formel III,It has now been found that it is possible to use a diene compound of the general formula II in which ST "stands for the rest (ABC rings) of a steroid molecule and R" stands for a straight-chain or branched-chain, saturated alkanoyl radical or for the benzoyl radical, with a vinyl ester of the general formula III,

Aus den zahlreichen, vorstehend genannten Vinylestern ist das Vinylacetat (Essigsäure- vinylester) besonders hervorzuheben, da es im großtechnischen Maßstab hergestellt wird und somit äußerst preisgünstig erhältlich ist (ca. 10 DM/1).
Bei den neuen Verfahren wird der Vinylester der allgemeinen Formel DI als Dienophü in einer Cycloaddition mit dem Dien der allgemeinen Formel D zur Reaktion gebracht (DiELS- ALDER-Reaktion). Als Beispiel ist im nachstehenden Schema die Umsetzung von 3,17-Di- acetoxy-estra-l,3,5(10),14,16-pentaen (1) mit Vinylacetat angegeben.Of the numerous vinyl esters mentioned above, the vinyl acetate (vinyl acetate) is particularly noteworthy, since it is manufactured on an industrial scale and is therefore extremely inexpensive to obtain (approx. 10 DM / 1). In the new processes, the vinyl ester of the general formula DI is reacted as dienophu in a cycloaddition with the diene of the general formula D (DiELS-ALDER reaction). The reaction of 3,17-di-acetoxy-estra-1,3,5 (10), 14,16-pentaen (1) with vinyl acetate is given as an example in the scheme below.

Verbindung der Verbindung der allgemeinen Formel I allgemeinen Formel ICompound of the compound of general formula I general formula I.
Das Ethenotrioltriacetat 6 ist somit auf direktem Wege erhältlich; ein aufwendiger Schritt wie die schwierige Reaktion des 16-Ketons 3 mit Natrium in flüssigem Ammoniak entfällt. Durch katalytische Hydrierung zum Ethanotrioltriacetat 7 sowie dessen Verseifung kann das Triol 5 erhalten werden. Die Verbindungen 6 und 7 stellen ebenso wie das Triol 5 Verbindungen der allgemeinen Formel I dar. Die Verbindungen 5, 6 und 7 (oder deren analoge Verbindungen, wenn eine andere Verbindung der allgemeinen Formel D als Verbindung 1 oder ein anderer Vinylester als Vinylacetat verwendet wurden) können nach gängigen Verfahren der organi¬ schen Chemie in andere Verbindungen der allgemeinen Formel I überführt werden. Die 3-, 16- und 17-Alkanoyloxy- bzw. -Hydroxygruppen weisen unterschiedliche Reaktivitäten auf.The ethenotriol triacetate 6 can thus be obtained directly; a complex step such as the difficult reaction of the 16-ketone 3 with sodium in liquid ammonia is eliminated. The triol 5 can be obtained by catalytic hydrogenation to ethanotriol triacetate 7 and its saponification. Compounds 6 and 7, like triol 5, are compounds of general formula I. Compounds 5, 6 and 7 (or their analogous compounds if another compound of general formula D was used as compound 1 or a vinyl ester other than vinyl acetate ) can be converted into other compounds of the general formula I by conventional organic chemistry processes. The 3-, 16- and 17-alkanoyloxy or hydroxy groups have different reactivities.
Weist die Verbindung der allgemeinen Formel D in der 3-Position einen Alkanoyloxyrest oder einen Kohlenwasserstoffoxyrest auf, so wird durch Verseifung bzw. Etherspaltung mit einer LEWIS-Säure nach gängigen Verfahren die 3-Hydroxygruppe freigesetzt, deren Vereste¬ rung oder Verätherung zu anderen Verbindungen der allgemeinen Formel I führt.If the compound of the general formula D has an alkanoyloxy radical or a hydrocarbonoxy radical in the 3-position, the 3-hydroxy group is released by saponification or ether cleavage with a LEWIS acid using conventional methods, and the esterification or etherification thereof to other compounds of the general formula I leads.
Die bevorzugte Reaktion elektronenreicher Diene mit elektronenarmen Dienophilen unter Bildung sechsgliedriger Carbocyclen gilt seit den ursprünglichen Arbeiten von DIELS und ALDER als der Prototyp der nach ihnen benannten Cycloaddition. In vielen Fällen erhöhen
elektronenspendende Liganden (z.B. -N(CH3)2. -OCH3, -CH3) im Dien und elektronenanzie¬ hende Liganden (z.B. -CN, -CO2CH3, -CHO, -NO2) im Dienophil die Reaktionsgeschwin¬ digkeit.The preferred reaction of electron-rich dienes with electron-poor dienophiles to form six-membered carbocycles has been the prototype of the cycloaddition named after them since the original work by DIELS and ALDER. In many cases, increase Electron donating ligands (eg -N (CH 3 ) 2. -OCH 3 , -CH 3 ) in the diene and electron-attracting ligands (eg -CN, -CO2CH3, -CHO, -NO 2 ) in the dienophile the reaction rate.
Es ist daher überraschend, daß es gelingt, die elektronenreiche Dienkomponente der allge¬ meinen Formel D mit dem elektronenreichen Dienophil der allgemeinen Formel DI unter DlELS-ALDER-Bedingungen zur Reaktion zu bringen.It is therefore surprising that it is possible to react the electron-rich diene component of the general formula D with the electron-rich dienophile of the general formula DI under DIELS-ALDER conditions.
Die Cycloaddition wird bei höheren Temperaturen durchgeführt, um die Reaktivität der Vinylesterkomponente zu verbessern. Man arbeitet mit dem reinen Vinylester oder unter Zusatz eines hochsiedenden Lösemittels, wie z. B. Mesitylen, Xylol oder Toluol, vorzugs¬ weise unter Druck, der sich im geschlossenen Reaktionsgefäß von selbst einstellt. Als Bei¬ spiel seien hier die typischen Reaktionsbedingungen für die Addition von Vinylacetat (Siedepunkt: 72-73 °C) an 3,17-Diacetoxy-estra-l,3,5(10),14,16-pentaen (1) angegeben:The cycloaddition is carried out at higher temperatures in order to improve the reactivity of the vinyl ester component. One works with the pure vinyl ester or with the addition of a high-boiling solvent, such as. As mesitylene, xylene or toluene, preferably under pressure, which sets itself in the closed reaction vessel. The typical reaction conditions for the addition of vinyl acetate (boiling point: 72-73 ° C.) to 3,17-diacetoxy-estra-1,3,5 (10), 14,16-pentaen (1) are given here as an example :
Reaktionstemperatur: 180 - 200 °C, Druck: ca. 8 - 10 bar.Reaction temperature: 180 - 200 ° C, pressure: approx. 8 - 10 bar.
Die Ausbeute des DiELS-ALDER-Adduktes 6, das sich unter diesen Bedingungen Stereo- und regioselektiv bildet, beträgt ca. 50 % der Theorie.The yield of the DiELS-ALDER adduct 6, which forms stereo- and regioselectively under these conditions, is approximately 50% of theory.
