Description
Fremgangsmåte til fremstilling av a,p-umettede ketosteroider som ved (5-carbonatoniet har en methylgruppe. Process for the production of a,p-unsaturated ketosteroids in which the (5-carbonatonium) has a methyl group.
Fra tysk patentskrift nr. 1 023 764 er From German patent document no. 1 023 764 is
det kjent at man kan fremstille a,(3-umet-tede ketosteroider som bærer en methylgruppe på carbonatomet i (3-stillingen, ved termisk spaltning av pyrazoliner som kan fåes ved tilleiring av diazomethan til car-bon-til-carbon-dobbeltbindingen i a,(3-umettede ketoner. Den termiske spaltning av sådanne pyrazoliner er imidlertid en prosess som er vanskelig å beherske ved ut-førelse i industriell målestokk og i høyt vakuum. It is known that a,(3-unsaturated ketosteroids bearing a methyl group on the carbon atom in the (3-position) can be prepared by thermal cleavage of pyrazolines which can be obtained by adding diazomethane to the carbon-to-carbon double bond in a ,(3-unsaturated ketones. The thermal cleavage of such pyrazolines is, however, a process that is difficult to master when carried out on an industrial scale and in high vacuum.
Man har derfor bestrebet seg på å er-statte den termiske spaltning av vedkommende pyrazoliner med på sikrere måte ut-førbare arbeidsmåter og har for dette formål foreslått anvendelse av katalysatorer (se tyske patentskrifter nr. 1 096 353 og nr. Efforts have therefore been made to replace the thermal decomposition of the pyrazolines in question with methods that can be carried out in a safer manner and, for this purpose, the use of catalysts has been proposed (see German patent documents no. 1 096 353 and no.
1 107 663). Herved har det imidlertid vist 1,107,663). Hereby, however, it has shown
seg at bruken av de først anvendte sterkt sure katalysatorer som perklorsyre, fluor-borsyre eller bortrifluoridetherat oppløst i et egnet organisk oppløsningsmiddel visst-nok bevirker den ønskede nitrogenavspalt-ning allerede ved romtemperatur, men ved siden av de ønskede a,(3-umettede (3-methylketosteroider fortrinnsvis frembringer dannelse av de med disse isomere a,|3-methylen-ketosteroider. It can be seen that the use of the first used strongly acidic catalysts such as perchloric acid, fluoroboric acid or boron trifluoride etherate dissolved in a suitable organic solvent certainly causes the desired nitrogen decomposition already at room temperature, but next to the desired α,(3-unsaturated ( 3-methylketosteroids preferentially produce formation of those with these isomeric α,|3-methylene ketosteroids.
Der ble nu funnet at man allikevel It was now found that one anyway
kan rette den katalytiske nitrogenavspalt-ning fra vedkommende pyrazoliner mot en helt overveiende dannelse av a,|3-umettede (3-methylketosteroider når man sørger for at denne spaltning foregår ikke på en sur can direct the catalytic nitrogen cleavage from the pyrazolines in question towards a predominantly formation of α,|3-unsaturated (3-methylketosteroids when it is ensured that this cleavage does not take place on an acidic
katalysator i homogen oppløsning, men på grenseflaten av et surt adsorpsjonsmiddel som er oppløst eller suspendert i et opp-løsningsmiddel som fortrinnsvis bare i liten grad eluerer pyrazolinet. Dette var ikke å forutse. catalyst in homogeneous solution, but on the interface of an acidic adsorbent which is dissolved or suspended in a solvent which preferably only elutes the pyrazoline to a small extent. This was not to be expected.
Særlig godt egnede adsorpsjonsmidler i fremgangsmåten ifølge oppfinnelsen er først og fremst de adsorpsjonsmidler som anvendes i adsorpsjonskromatografien som aluminiumoxyd, silikagel, blekejord, ione-utvekslere og lignende. Slike adsorpsjonsmidler må imidlertid når de ikke i seg selv reagerer surt, aktiveres ved syrebehand-ling på i og for seg kjent måte for å være virksomme for foreliggende oppfinnelses formål, og de må efter syrebehandlingen bibeholde en viss syregrad. Dette kontrolle-res hensiktsmessig ved å suspendere en prøve av det syrebehandlede og efterpå tør-rede adsorpsjonsmiddel i en bestemt mengde vann og bestemme suspensjonens pH-verdi før anvendelsen. Particularly suitable adsorbents in the method according to the invention are primarily the adsorbents used in adsorption chromatography such as aluminum oxide, silica gel, bleaching earth, ion exchangers and the like. Such adsorbents, however, when they do not themselves react acidly, must be activated by acid treatment in a manner known per se in order to be effective for the purposes of the present invention, and they must retain a certain degree of acidity after the acid treatment. This is conveniently checked by suspending a sample of the acid-treated and subsequently dried adsorbent in a specific amount of water and determining the pH value of the suspension before use.
Til utførelse av spaltningen ifølge oppfinnelsen suspenderes det tørre sure adsorpsjonsmiddel i et likeledes tørt organisk oppløsningsmiddel ved omrøring eller ryst-ning. Det pyrazolin som skal spaltes til-føres enten i finpulverisert tilstand eller oppløst i suspensjonen av det sure adsorpsjonsmiddel. Man omrører eller ryster derpå inntil nitrogenutviklingen opphører, fraskiller adsorpsjonsmidlet og behandler det med et best mulig eluerende oppløs-ningsmiddel for å oppløse resterende reak-sjonsprodukter fra adsorpsjonsmidlet. Re-aksjonsproduktene isoleres derpå ved for-dampning av oppløsningsmidlet og renses om nødvendig på vanlig måte. To carry out the cleavage according to the invention, the dry acidic adsorbent is suspended in a similarly dry organic solvent by stirring or shaking. The pyrazoline to be split is supplied either in a finely powdered state or dissolved in the suspension of the acidic adsorbent. One then stirs or shakes until nitrogen evolution ceases, separates the adsorbent and treats it with the best possible eluting solvent to dissolve remaining reaction products from the adsorbent. The reaction products are then isolated by evaporation of the solvent and, if necessary, purified in the usual way.
Det er bemerkelsesverdig at spalt-ningsmetoden ifølge oppfinnelsen også kan anvendes på sådanne pyrazoliner som er-faringsmessig ikke lar seg spalte under anvendelse av den tidligere foreslåtte spalt-ningsmetode, som f. eks. diazomethantillei-ringsproduktene av A^-ketosteroider. Slike forbindelser er i virkeligheten A<2->pyrazoliner (i det infrarøde område: sterke C = N-bånd ved 6,45 \ i, mot rødt forskjøvne («rotverschobene») keto-bånd ved 6,96 \ i — som følge av konjugasjon til 3-ketogruppen — til forskjell fra de A<1->pyrazoliner som dannes ved tilleiring av diazomethan til A1'4',<i->ketosteroider eller A<1>(<5->20-ketosteroider — i det infrarøde område svakt N = N-bånd ved 6,4—6,45 [ i, keto-bånd i det nor-male område). Denne forskjell i konstitu-sjonen kan være grunnen til at spaltningen under de hittil anvendte betingelser ikke inntreffer. Det antas at der ved hjelp av adsorpsjonsmidlet primært oppstår en annen pyrazolinforbindelse av A<2->pyrazo-linene, en forbindelse som er lett spaltbar. It is noteworthy that the cleavage method according to the invention can also be applied to such pyrazolines which experience-wise cannot be cleaved using the previously proposed cleavage method, such as e.g. the diazomethane addition products of A^-ketosteroids. Such compounds are in reality A<2->pyrazolines (in the infrared region: strong C = N bands at 6.45 \ i, against red-shifted ("rotverschobene") keto bands at 6.96 \ i — as a result of conjugation to the 3-keto group — in contrast to the A<1->pyrazolines which are formed by addition of diazomethane to A1'4',<i->ketosteroids or A<1>(<5->20-ketosteroids — in that infrared region weak N = N-band at 6.4-6.45 [i, keto-band in the normal range).This difference in the constitution may be the reason why the cleavage does not occur under the conditions used so far. It is believed that with the aid of the adsorbent, another pyrazoline compound of the A<2->pyrazolines, a compound which is easily cleavable, is primarily formed.
Utgangsmaterialene for fremgangsmåten ifølge oppfinnelsen kan være sub-stituert på hvilkensomhelst måte. Således kan de ha substituenter bestående av frie eller forestrede OH-grupper eller frie eller i funksjonell henseende endrede ketogrup-per, eller halogenatomer. Som forestrede hydroxylgrupper kommer der fortrinnsvis i betraktning hydroxylgrupper som er forestret med alifatiske, alicycliske, aralifa-tiske, aromatiske eller heterocycliske car-boxylsyrer med fra 1 til 11 carbonatomer i molekylet, f. eks. med eddiksyre, kloreddik-syre, propionsyre, smørsyre, diethyleddik-syre, ønanthsyre, caprylsyre, undecylen-syre, cyclopentylpropionsyre, ravsyre, phe-nyleddiksyre, furancarbonsyre, fenoxy-eddiksyre, caprinoyleddiksyre og benzoe-syre. The starting materials for the method according to the invention can be substituted in any way. Thus, they can have substituents consisting of free or esterified OH groups or free or functionally altered keto groups, or halogen atoms. Esterified hydroxyl groups preferably include hydroxyl groups which are esterified with aliphatic, alicyclic, araliphatic, aromatic or heterocyclic carboxylic acids with from 1 to 11 carbon atoms in the molecule, e.g. with acetic acid, chloroacetic acid, propionic acid, butyric acid, diethylacetic acid, enanthic acid, caprylic acid, undecylenic acid, cyclopentylpropionic acid, succinic acid, phenylacetic acid, furancarboxylic acid, phenoxyacetic acid, caprinoyacetic acid and benzoic acid.

(Den sure silikagel fremstilles av nøytral tørr silikagel ved suspensjon i IN saltsyre, frafiltrering av saltsyren efter 12 timer og tørring i 20 timer ved 120° C). 5 g of (A-"-pyrazolino)-4', 3' : 1,2a-andro-stan-17|3-ol-3-one is boiled under reflux cooling and stirring for 15 hours (overnight) in 750 ml carbon tetrachloride with 235 g of acidic silica gel (The acidic silica gel is prepared from neutral dry silica gel by suspension in IN hydrochloric acid, filtering off the hydrochloric acid after 12 hours and drying for 20 hours at 120° C).
Silikagelen frafiltreres og eftervaskes med ca. 2 liter eddikester. Filtratene blandes og inndampes til tørrhet. Det herved erholdte råprodukt veier 4,5 g (UV.: e^o = 8100, <e>2;)7 = 2700, N = 1 pst.) og oppvarmes på dampbad i iy2 time med 15 ml pyridin_ og 9 ml eddiksyreanhydrid. Den erholdte oppløsning blandes med isvann under om-røring. Blandingen ekstraheres med ether, og etherekstrakten vaskes først med IN saltsyre, derpå med natriumbikarbonat-oppløsning og sluttelig med vann. Ekstrak-tet tørres derpå over natriumsulfat og inndampes til tørrhet i vakuum. Residuet kromatograferes gjennom nøytral silikagel (10 pst. vann). Med methylenklorid isoleres i en første fraksjon 1 g av et blandet produkt og derpå 3,1 g rått 1-methyl-A<1->androsten-17(3-ol-3-on-17-acetat. The silica gel is filtered off and washed with approx. 2 liters of vinegar. The filtrates are mixed and evaporated to dryness. The crude product thus obtained weighs 4.5 g (UV.: e^o = 8100, <e>2;)7 = 2700, N = 1 per cent) and is heated on a steam bath for 1y2 hours with 15 ml of pyridine_ and 9 ml of acetic anhydride . The obtained solution is mixed with ice water while stirring. The mixture is extracted with ether, and the ether extract is first washed with 1N hydrochloric acid, then with sodium bicarbonate solution and finally with water. The extract is then dried over sodium sulphate and evaporated to dryness in vacuo. The residue is chromatographed through neutral silica gel (10% water). With methylene chloride, 1 g of a mixed product and then 3.1 g of crude 1-methyl-A<1->androstene-17(3-ol-3-one-17-acetate) are isolated in a first fraction.
Ved omkrystallisasjon fra isopropylether får man 2,2 g rent produkt med smeltepunkt 140—141° C. Recrystallization from isopropyl ether gives 2.2 g of pure product with a melting point of 140-141° C.
Eksempel 2. Example 2.

Blandingen avkjøles derpå, aluminiumoxydet frafiltreres og eftervaskes med ca. 2 liter eddikester. Efter inndampning av opp-løsningen omkrystalliseres der fra isopropylether. Det herved erholdte 1-methyl-A^androsten-np-ol-S-on smelter ved 150 —152° C. UV.: E2I() = 13 300. 4.0 g of (A<2>'-pyrazolino)-4', 3': 1,2a-androstan-17(3-ol-3-one is heated under reflux and stirring with 200 g of acidic aluminum oxide (preparation see below- for) and 400 ml of carbon tetrachloride for 3 days. The mixture is then cooled, the aluminum oxide is filtered off and washed with approx. 2 liters of acetic acid. After evaporation of the solution, it is recrystallized from isopropyl ether. 1-methyl-A^androsten-np-ol is thereby obtained -S-on melts at 150 —152° C. UV.: E2I() = 13,300.
For å få ytterligere mengder av for-bindelsen ekstraheres det frafiltrerte aluminiumoxyd varmt med eddikester. Eks-traktet inndampes til tørrhet og residuet blandes med den inndampede moderlut fra fremstillingen av den ovenfor angitte rene forbindelse. Man forestrer og kromatogra-ferer således som angitt i eksempel 1. Man får herved en ytterligere mengde 1-methyl-A<1->androsten-17(3-ol-3-on som 17-acetat. Forbindelsens smeltepunkt er 137—138° C. To obtain further amounts of the compound, the filtered aluminum oxide is extracted hot with vinegar. The extract is evaporated to dryness and the residue is mixed with the evaporated mother liquor from the preparation of the pure compound indicated above. It is thus esterified and chromatographed as indicated in example 1. This gives a further amount of 1-methyl-A<1->androsten-17(3-ol-3-one as 17-acetate. The compound's melting point is 137-138 °C.
