R~* er et hydrogenatom eller en i a- eller (3-stilling stående alkylgruppe med 1 til 4 carbonatomer. ;Forbindelsene med den generelle formel I har en sterk affinitet til gestagenreseptoren uten selv å ha gestagen aktivitet. De er konkurrerende antagonister av progesteron (anti-gestagener) og er egnet til utløsning av aborter, da de fortrenger det til opprettholdelse av svangerskapet nød-vendige progesteron fra reseptoren. Forbindelsene er derfor verdifulle og interessante med henblikk på deres anvendelse som terapeutisk aktive forbindelser. ;Tilsvarende forbindelser i estranrekken er allerede beskrevet som antigestagent virksomme forbindelser i Fertility and Sterility 40 (1982), side 253. ;De hittil kjente struktur-virkningsforhold for konkurrerende progesteron-antagonister tyder på at en 1,3-diaksial anordning av llfi-arylrest og 133-alkylgruppe er tvingende nødvendig for utfoldelsen av antigestagen aktivitet. Desto mer overraskende er den sterke og selektive antagonistiske virkning av 13a-alkylgonaner av formel I hvor en helt annen molekyltopografi sammenlignet med estranrekken, oppvises. ;Til erkjennelse av den antigestagene virkning av forbindelsene ifølge oppfinnelsen ble den abortive virkning i en tidligere fase post nidation (forsøk I) og i en fremskreden fase post nidtation (forsøk II) undersøkt. ;Forsøkene ble utført på hunnrotter i en vekt på ca. ;200 g. Etter parring ble svangerskapsbegynnelsen sikret ved påvisning av spermier i vaginalavstrykninger. Dagen for spermiepåvisningen regnes som dag 1 av graviditeten (= d 1 p.c.). ;Behandlingen av dyrene med den forbindelse f.eks. opp-løsningsmidlet som skal undersøkes, skjer efter nidation av blastocystene fra d 5 p.c. til d 7 p.c. (forsøk I) hhv. ;d 13 p.c. til d 15 p.c. (forsøk II). På d 9 p.c. hhv. ;d 17 p.c. ble dyrene avlivet og deres uteri undersøkt på implantater og resorpsjonssteder. Av alle uteri ble det tatt bilder. Mangelen på implantater ble bedømt som abort. ;Som antigestagener ble følgende undersøkt: ;A: 113-(4-dimethylaminofenyl)-17&-hydroxy-17a-propynyl-4,9- estradien-3-on (referanseforbindelse). ;B: 113-(4-dimethylaminofenyl)-173~hydroxy-17a-(3-hydroxy-propyl)-13a-methyl-4,9-gonadien-3-on (ifølge oppfinnelsen) . ;C: 113-(4-dimethylaminofenyl)-17a-hydroxy-173~(3-hydroxy-propyl)-13a-methyl-4,9-gonadien-3-on (ifølge oppfinnelsen) . ;Forsøksforbindelsene ble oppløst i en benzylbenzoat-ricinusoljeblanding (forhold 1:4). Bæremiddelvolumet pr. enkeltdose utgjorde 0,2 ml. Behandlingen skjedde subcutant (s.c .) . ;Forbindelsene B og C ifølge oppfinnelsen virker ved tidlig gravide rotter i doseringer på = 1,0 mg/d fullstendig abortfremkallende (abortrat: 4/4). I motsetning til dette oppviser referanseforbindelsen A maksimal abortutløsning (antigestågen) virkning først ved doser på = 3,0 mg/d (tabell 1) . ;Ved en fremskreden fase av svangerskapet (d 13 - 15 p.c.) utgjør prosentsatsen for komplette aborter ved 3 ganger dag-lig s.c. tilføring av 3,0 mg/d for B 35,4%, for C 52,3% og for sammenligningsforbindelsen A 3,5% (tabell 2). ;13a-alkylgonaner med den generelle formel I kan finne anvendelse i form av farmasøytiske preparater. Fremstill-ingen av preparatene skjer ved i og for seg kjente galeniske metoder ved blanding med organisk eller uorganisk inert bæremateriale som er egnet for enteral, percutan eller par-enteral anvendelse. ;Doseringen av virkestoffene ifølge oppfinnelsen ligger hos mennesker ved ca. 10 til 1000 mg pr. dag. ;Alkylgruppene i R<1> og R<11> i den generelle formel I skal inneholde 1 til 4 carbonatomer, idet methyl- og ethylgruppen ;er foretrukket. ;Analogifremgangsmåten ifølge oppfinnelsen er kjenne-tegnet ved at en forbindelse med den generelle formel: ;17 5 hvor R , R" og R er som ovenfor angitt, og Z er en ethylen-eller 2,2-dimethylpropylengruppe, bestråles med ultrafiolett lys, og det ved UV-bestråling erholdte 13-episteroid med den generelle formel: ;hvor R 1, R 2 , R 5og Z er som ovenfor angitt, på i og for seg kjent vis ved nucleofil addisjon på 17-ketonet, spaltning av 3-ketalbeskyttelsen og vannavspaltning fra 4,5-stillingen, overføres til forbindelsene med den generelle formel I. ;Ved bestråling med ultrafiolett lys overføres 133-alkylsteroidene med den generelle formel II i godt utbytte til 13-episteroidene (13a-alkylsteroider) med den generelle formel III. Forbindelsene av generell formel IT kan fremstilles som beskrevet i US patentskrift 4 233 296 og 4 386 085. ;Det gode utbytte av omvandlingsproduktet er overraskende. Det har riktignok lenge vært kjent at 17-oxosteroider av normalrekken ved UV-bestråling er overførbare til 13-episteroider (A. Butenandt et al., Ber. Deutsch. Chém. Ges. 74, 1308 (1941)); men man får imidlertid alltid blandinger av utgangsmateriale og epimerisert forbindelse, bestrålings-tidene utgjorde flere timer, og utbyttet var overordentlig lavt. Derfor har også søkingen etter en alternativ, kjemisk tilgang på 13-epi-rekken stadig vært aktuell som et tidligere arbeide av Barton et al., J.C.S. Perkin I, 2163 (1977), viser. Dette alternativ er imidlertid ikke egnet til fremstilling av forbindelser av type I. Det ble funnet at bestrålingen av forbindelsene av type II under bestemte betingelser tar et vesentlig gunstigere forløp enn i rekken av 11-usubstituerte 17-oxosteroider. Således utgjør de gjennomsnittlige be-strålingstider bare 10 - 30 minutter, og utbyttet på 13-episteroid ligger mellom 60 - 80%. Bestrålingsproduktene kan eventuelt omsettes videre uten kromatografisk rensing. En vesentlig forutsetning for et godt utbytte er det riktige valg av oppløsningsmiddel, konsentrasjonen av substratet som skal bestråles og den nøyaktige overholdelse av bestrål-ingsvarigheten. Disse parametere må bestemmes spesielt for hvert nytt substrat. ;Bestrålingen utføres med det fulle lys av en Hg-høy-trykkslampe i kvartsglassapparaturen. Temperaturen på reak-sjonsoppløsningen innstilles på ca. 25°C, konsentrasjonen av oppløsningen utgjør 0,1 - 1,0 vekt%. Som oppløsningsmiddel anvendes fortrinnsvis tetrahydrofuran og dioxan, men også upolare aprotiske oppløsningsmidler som hexan, cyclohexan, benzen, toluen og blandinger derav, kan anvendes. Bestrål-ingsvarigheten utgjør ca. 10 - 50 minutter. ;De på denne måte erholdte 13-episteroider III overføres ved de vanlige prosesser ved nucleofil addisjon på 17-ketonet og etterfølgende reaksjoner til sluttforbindelsen med den generelle formel I. Den nucleofile addisjon på III forløper i alminnelighet under dannelse av to mulige, isomere former ved C-17 som imidlertid er lett skillbare ved kromatografi eller fraksjonert krystallisasjon. I mange tilfelle er begge isomerer farmakologisk virksomme selv om det foreligger forskjeller i virkningsstyrken. ;Den nucleofile addisjon av acetylen (ethyn) eller propyn skjer ved hjelp av et middel som avgir gruppen -C=CH eller -CsC-CH^. Slike midler er f.eks. alkalimetallacetylider som f.eks. kalium- og lithiumacetylid, hhv. -methylacetylid. ;Den metallorganiske forbindelse kan også dannes in situ og bringes til reaksjon med 17-ketonet med formel III. Således kan man f.eks. i et egnet oppløsningsmiddel la acetylen og et alkalimetall, særlig kalium, natrium eller lithium, innvirke på 17-ketonet i et egnet oppløsningsmiddel i nærvær av en alkohol eller i nærvær av ammoniakk. Alkalimetallet kan også bringes til innvirkning i form av f.eks. methyl-eller butyllithium. Som oppløsningsmiddel er særlig dialkyl-ether, tetrahydrofuran, dioxan, benzen og toluen egnet. ;17-ethynyl-17-hydroxyforbindelsene lar seg hydratisere ;i alkoholisk oppløsning under kvikksølvkatålyse til 17-acetyl-17-hydroxyforbindelsene (Chem. Ber. 111 (1978) 3086 - 3093). ;Innføringen av 3-hydroxypropan, hhv. 3-hydroxypropen i 17-stillingen, skjer ved omsetning av 17-ketonet med metal-liserte derivater av propargylalkohol, f.eks. med l-lithium-3-tetrahydropyran-2'-yloxy-propyn-1, til 17-(3-hydroxy-l-propynyl) -17-hydroxyforbindelsene , som derpå hydreres til 17-(3-hydroxypropyl-, hhv. 3-hydroxypropenyl)-17-hydroxy-forbindelsene . Hydrogeneringen må utføres under betingelser som bare tillater angrep på C-C-trippelbindingen uten å av-mette den tetrasubstituerte 9(10)-dobbeltbinding. Innføring av de homologe hydroxyalkan- og hydroxyalken-grupper av generell formel -CH=CH-(CH2)n0H eller -CH2~CH2-(CH2)n0H skjer på tilsvarende måte med homologer av propargylalkohol. Dette skjer f.eks. ved hydrogenering ved værelsetemperatur og normaltrykk i oppløsningsmidler som methanol, ethanol, propanol, tetrahydrofuran (THF) eller eddikester under tilsetning av edelmetallkatalysatorer som platina eller palladium. ;Forbindelsen med den Z-konfigurerte dobbeltbinding i hydroxypropenylgruppen oppstår ved hydrogenering av den acetyl-eniske trippelbinding med en desaktivert edelmetallkatalysator (J. Fried, J.A. Edwards: Organic Reactions in Steroid Chemistry, Van Nostrand Reinhold Company 1972, side 134, og H.O. House: Modern Synthetic Reactions 1972, side 19). Som desaktiverte edelmetallkatalysatorer kommer eksempelvis 10% palladium på bariumsulfat i nærvær av et amin eller 5% palladium på calciumcarbonat under tilsetning av bly(II)-acetat på tale. Hydreringen avbrytes etter opptagelse av en ekvivalent hydrogen. ;Forbindelsen med den E-konfigurerte dobbeltbinding i hydroxypropenylgruppen dannes ved reduksjon av den acetylen-iske trippelbinding på i og for seg kjent vis. I littera-turen er en hel rekke metoder til overføring av alkyner til trans-olefiner beskrevet, eksempelvis ved reduksjon med natrium i flytende ammoniakk (J. Am." Chem. Soc. 6_3 (1941) 216), med natriumamid i flytende ammoniakk (J. Chem. Soc. 1955, 3558), med lithium i lavmolekylære aminer (J. Am. Chem. Soc. Il (1955) 3378), med boraner (J. Am. Chem. Soc. 93. ;(1971) 3395 og 9J (1971) 6560), med diisobutylaluminiumhydrid og methyllithium (J. Am. Chem. Soc. 8j) (1967) 5085) og særlig med lithiumaluminiumhydrid/alkoholat (J. Am. Chem. Soc. 89 (1967) 4245). En annen mulighet er reduksjonen av trippelbindingen med krom(II)-sulfat i nærvær av vann eller dimethylformamid i svakt surt miljø (J. Am. Chem. Soc. 8j> ;(1964) 4358) såvel som vanligvis reduksjonen ved innvirkning av overgangsmetallforbindelsene under forandring av oxyda-sjonstrinnet. ;Oppbyggingen av 17-cyanmethyl-sidekjeden skjer på i og for seg kjent vis fra 17-ketonet med den generelle formel III, f.eks. over 17-spiroepoxydet og spaltning av spiroepoxydet med HCN ifølge Z. Chem. 18 (1978) 259 - 260. Innføring av cyanalkansidekjeden -(CH2)n~CH2CN med n = 1 - 3 skjer eksempelvis ved addisjon av Li-(CH2)n~CH2CN på 17-ketonet. ;Også innføringen av 17-hydroxyacetyl-sidekjeden skjer på i og for seg kjent vis, eksempelvis ifølge den i J. Org. Chem. 4_7 (1982), 2993 - 2995, beskrevne metode. ;Frie hydroxygrupper i 17-stillingen kan på i og for ;seg kjent vis forestres. ;Etter omsetning (nucleofil addisjon) av 17-ketonet blir forbindelsene med formel III behandlet til vannavspaltning under dannelse av 4(5)-dobbeltbindingen og til samtidig ketalspaltning og fjerning av eventuelt tilstedeværende ytterligere med syre avspaltbare beskyttelsesgrupper med syre eller en annen sur ioneutbytter. ;Den sure behandling skjer på i og for seg kjent vis idet forbindelsen med formel III som inneholder en 3-ketal-gruppe og en 5a-hydroxygruppe og en eventuelt O-beskyttet 17-(3-hydroxypropyl)-gruppe, oppløses i et med vann blandbart oppløsningsmiddel, som vandig methanol, ethanol eller aceton, og at man lar katalytiske mengder av mineral- eller sulfonsyre, som saltsyre, svovelsyre, fosforsyre, perklor-syre eller p-toluensulfonsyre eller en organisk syre, som eddiksyre, innvirke så lenge på oppløsningen inntil vann er avspaltet og beskyttelsesgruppene er fjernet. Omsetningen, som forløper best ved temperaturer fra 0 til 100°C, kan også foretas med en sur ioneutbytter. Forløpet av omsetningen kan følges med analytiske metoder, f.eks. ved tynnskikts-kromatografi på uttatte prøver. ;Eksempel 1 ;a) En oppløsning av 2,0 g 11(3- (4-dimethylaminofenyl)-3, 3-(2,2-dimethylpropan-l,3-dioxy)-5a-hydroxy-9(10)-estren-17-on ;(smp. 143-145°C) i 300 ml absolutt tetrahydrofuran (THF) bestråles i 16 minutter ved 25°C med en Hg-høytrykkslampe (Philips HPK 125, neddykningslampe, kvartsglassreaktor). Derpå avdestilleres oppløsningsmidlet i vakuum, og residuet kromatograferes over aluminiumoxyd (Merck, nøytral, trinn III) med hexan/eddiksyreester. Man får 1,46 g 113-(4-dimethylaminofenyl)-3,3-(2,2-dimethylpropan-l,3-dioxy)-5a-hydroxy-13a-methyl-9(10)-gonen-17-on som farveløs olje. ;b) Absolutt THF (248 ml) mettes med acetylen ved 5°C ved 30 minutters innledning. Derpå tildryppes langsomt 51 ml av ;en 15%-ig oppløsning av n-butyllithium i hexan, og det om-røres i ytterligere 15 minutter under isvannkjøling. En opp-løsning av 2,7 g 113-(4-dimethylaminofenyl)-3,3-(2,2-dimethyl-propan-l, 3-dioxy)-5a-hydroxy-13a-methyl-9-gonen-17-on i 40 ml absolutt THF tildryppes i løpet av 15 minutter til suspensjonen av lithiumacetylidet, og det omrøres i ytterligere 2 timer ved værelsetemperatur. For opparbeidelse helles i isvann og ekstraheres med eddiksyreester. Det således erholdte råprodukt (2,85 g) anvendes uten ytterligere rensning i det følgende trinn. c) 2,8 g av det under b) erholdte råprodukt suspenderes i 29 ml 70%-ig vandig eddiksyre og omrøres i 3 timer ved 50°C. ;Etter avkjøling fortynnes med ca. 100 ml vann, og det innstilles ved tilsetning av konsentrert vandig NH^-oppløsning på en pH-verdi på 10,5. Etter ekstraksjon med eddiksyreester får man en oljeaktig isomerblanding som skilles ved søyle-kromatografi på kiselgel med hexan/eddiksyreester. Man får i elueringsrekkefølge: 1. 530 mg 113-(4-dimethylaminofenyl)-17a-ethynyl-173-hydroxy-13a-methyl-4,9-gonadien-3-on med smp. 120-123°C (eddiksyreester/diisopropylether) og 2. 1,33 g 113-(4-dimethylaminofenyl)-173~ethynyl-17a-hydroxy-13a-methyl-4,9-gonadien-3-on med smp. 201-204°C (eddiksyreester). d) En suspensjon av 1,02 g kvikksølvoxyd (HgO, rødt) i 20 ml vann blir etter tilsetning av 0,87 ml konsentrert svovelsyre omrørt i 30 minutter ved 60°C. 9 ml av denne kvikksølvsaltoppløsning helles i en oppløsning av 3,25 g 113-(4-dimethylaminofenyl)-173-ethynyl-17ct-hydroxy-13a-methyl-4,9-gonadien-3-on i 32 ml iseddik. Derpå omrøres i 2 timer ved 60°C. Til opparbeidelse heller man den avkjølte reak-sjonsoppløsning i isvann, innstiller ved tilsetning av konsentrert vandig NH^-oppløsning en pH-verdi på 10,5 og ekstraherer med ethylacetat. Det således erholdte oljeaktige råprodukt krystalliseres fra methylenklorid/diisopropyl-ether. Man får 2,37 g 113-(4-dimethylaminofenyl)-17a-hydroxy-13a-methyl-18,19-dinor-4,9-pregnadien-3,20-dion med smp. 224-225°C. e) En suspensjon av 2,3 g 113-(4-dimethylaminofenyl)-17a-hydroxy-13a-methyl-18,19-dinor-4,9-pregnadien-3,20-dion i 58 ml toluen blir etter tilsetning av 11/6 ml acetanhydrid og 5,8 g 4-dimethylaminopyridin omrørt i 20 timer ved 25°C. Derpå helles i mettet NaHCO^-oppløsning og ekstraheres med ethylacetat. Råproduktet kromatograferes på 200 g silicagel med hexan/ethylacetat. Etter krystallisasjon av hovedfraksjonen fra hexan/ethylacetat får man 1,71 g 17ct-acetoxy-113-(4-dimethylaminofenyl)-13a-methyl-18,19-dinor-4,9-pregna-dien-3,20-dion med smp. 194-195°C. ;Eksempel 2 ;a) En oppløsning av 1,8 g 113-(4-diethylaminofenyl)-3,3-(2,2-dimethylpropan-l,3-dioxy)-5a-hydroxy-9-estren-17-on ;(smp. 223-226°C) i 300 ml THF bestråles under betingelsene i eksempel la) i 26 minutter. Etter kromatografi av råproduktet får man 1,58 g 113-(4-diethylaminofenyl)-3,3-(2,2-dimethyl-propan-l ,3-dioxy)-5a-hydroxy-13a-methyl-9-gonen-17-on som en farveløs olje. ;b) Av 3,94 g 3-tetrahydropyran-2<1->yloxy-l-propyn i 85 ml absolutt THF og 23,1 ml av en 15%-ig oppløsning av n-butyllithium i hexan fremstilles ved 0°C den lithiumorganiske forbindelse. Derpå tildryppes en oppløsning av 3,53 g av det under 2a) beskrevne produkt i 71 ml absolutt THF og omrører i 4 timer ved værelsetemperatur. Reaksjonsoppløsningen helles derpå i isvann og ekstraheres med eddiksyreester. Råproduktet (3,85 g) 113-(4-diethylaminofenyl)-3,3-(2,2-dimethylpropan-1,3-dioxy)-13a-methyl-17a-[3-(tetrahydropyran-2-yloxy)-1-propynyl]-9-gonen-5a,173-diol og 113-(4-diethyl-aminof enyl) -3,3-(2,2-dimethylpropan-l,3-dioxy)-13a-methyl-173-[3-(tetrahydropyran-2-yloxy)-1-propynyl]-9-gonen-5a,17a-diol blir uten ytterligere rensning anvendt til hydrogener ingen. c) 3,85 g av det under 2b) erholdte råprodukt blir, i 95 ml ethanol etter tilsetning av 400 mg 10%-ig palladiumkull, hydrogenert ved værelsetemperatur og normaltrykk.

R~* is a hydrogen atom or an alkyl group in the a- or (3-position) with 1 to 4 carbon atoms. The compounds of the general formula I have a strong affinity for the progestogen receptor without themselves having progestogen activity. They are competitive antagonists of progesterone (anti-gestagens) and are suitable for triggering abortions, as they displace the progesterone necessary for the maintenance of pregnancy from the receptor. The compounds are therefore valuable and interesting with a view to their use as therapeutically active compounds. Corresponding compounds in the estran series are already described as antigestagen active compounds in Fertility and Sterility 40 (1982), page 253. ;The hitherto known structure-activity relationships for competitive progesterone antagonists suggest that a 1,3-diaxial arrangement of 11fi-aryl residue and 133-alkyl group is imperative necessary for the unfolding of antigestagen activity All the more surprising is the strong and selective antagonistic action a v 13a-alkylgonanes of formula I where a completely different molecular topography compared to the estran series is exhibited. In recognition of the antigestagen effect of the compounds according to the invention, the abortive effect in an earlier phase post nidation (experiment I) and in an advanced phase post nidtation (experiment II) was examined. The experiments were carried out on female rats weighing approx. ;200 g. After mating, the onset of pregnancy was ensured by detection of sperm in vaginal swabs. The day of the sperm detection is considered day 1 of the pregnancy (= d 1 p.c.). ;The treatment of the animals with that connection e.g. the solvent to be examined occurs after nidation of the blastocysts from d 5 p.c. to d 7 p.c. (experiment I) or ;d 13 p.c. to d 15 p.c. (attempt II). On d 9 p.c. respectively ;d 17 p.c. the animals were euthanized and their uteri examined for implants and resorption sites. Photographs were taken of all uteri. The lack of implants was judged as abortion. As antigestagens, the following were investigated: A: 113-(4-dimethylaminophenyl)-17β-hydroxy-17α-propynyl-4,9-estradien-3-one (reference compound). ;B: 113-(4-dimethylaminophenyl)-173~hydroxy-17a-(3-hydroxy-propyl)-13a-methyl-4,9-gonadien-3-one (according to the invention). ;C: 113-(4-dimethylaminophenyl)-17a-hydroxy-173~(3-hydroxy-propyl)-13a-methyl-4,9-gonadien-3-one (according to the invention). ;The test compounds were dissolved in a benzyl benzoate-castor oil mixture (ratio 1:4). The carrier volume per single dose was 0.2 ml. The treatment took place subcutaneously (s.c.). ;Compounds B and C according to the invention act in early pregnant rats in dosages of = 1.0 mg/d as completely abortive (abortion rate: 4/4). In contrast, the reference compound A exhibits maximal abortifacient (antigestagen) action only at doses of = 3.0 mg/d (Table 1). At an advanced stage of pregnancy (d 13 - 15 p.c.) the percentage of complete abortions with 3 times daily s.c. addition of 3.0 mg/d for B 35.4%, for C 52.3% and for the comparison compound A 3.5% (Table 2). ;13a-alkylgonanes of the general formula I can find use in the form of pharmaceutical preparations. The preparations are made by per se known galenic methods by mixing with organic or inorganic inert carrier material which is suitable for enteral, percutaneous or parenteral use. ;The dosage of the active substances according to the invention is in humans at approx. 10 to 1000 mg per day. The alkyl groups in R<1> and R<11> in the general formula I must contain 1 to 4 carbon atoms, the methyl and ethyl groups being preferred. The analogous method according to the invention is characterized by the fact that a compound with the general formula: 17 5 where R , R" and R are as indicated above, and Z is an ethylene or 2,2-dimethylpropylene group, is irradiated with ultraviolet light, and the 13-episteroid obtained by UV irradiation with the general formula: where R 1 , R 2 , R 5 and Z are as indicated above, in a manner known per se by nucleophilic addition on the 17-ketone, cleavage of 3- the ketal protection and water removal from the 4,5-position are transferred to the compounds of the general formula I. ;On irradiation with ultraviolet light, the 133-alkylsteroids of the general formula II are transferred in good yield to the 13-episteroids (13a-alkylsteroids) of the general formula III. The compounds of general formula IT can be prepared as described in US patents 4,233,296 and 4,386,085. only to 13-episteroids (A. Butenandt et al., Ber. Deutsch. Chem. Ges. 74, 1308 (1941)); however, one always obtains mixtures of starting material and epimerized compound, the irradiation times were several hours, and the yield was exceedingly low. Therefore, the search for an alternative, chemical approach to the 13-epi series has also been relevant as a previous work by Barton et al., J.C.S. Perkin I, 2163 (1977), shows. However, this alternative is not suitable for the preparation of compounds of type I. It was found that the irradiation of the compounds of type II under certain conditions takes a significantly more favorable course than in the series of 11-unsubstituted 17-oxosteroids. Thus, the average irradiation times are only 10 - 30 minutes, and the yield of 13-episteroid is between 60 - 80%. The irradiation products can optionally be reacted further without chromatographic purification. An essential prerequisite for a good yield is the correct choice of solvent, the concentration of the substrate to be irradiated and the exact observance of the irradiation duration. These parameters must be determined specifically for each new substrate. ;The irradiation is carried out with the full light of a Hg high-pressure lamp in the quartz glass apparatus. The temperature of the reaction solution is set to approx. 25°C, the concentration of the solution amounts to 0.1 - 1.0% by weight. Tetrahydrofuran and dioxane are preferably used as solvents, but non-polar aprotic solvents such as hexane, cyclohexane, benzene, toluene and mixtures thereof can also be used. The irradiation duration amounts to approx. 10 - 50 minutes. ;The 13-episteroids III obtained in this way are transferred by the usual processes by nucleophilic addition to the 17-ketone and subsequent reactions to the final compound with the general formula I. The nucleophilic addition of III generally proceeds with the formation of two possible, isomeric forms by C-17 which are, however, easily separable by chromatography or fractional crystallization. In many cases, both isomers are pharmacologically active, even if there are differences in potency. ;The nucleophilic addition of acetylene (ethyne) or propyne takes place with the aid of an agent which emits the group -C=CH or -CsC-CH^. Such funds are e.g. alkali metal acetylides such as e.g. potassium and lithium acetylide, respectively -methylacetylide. The organometallic compound can also be formed in situ and reacted with the 17-ketone of formula III. Thus, one can e.g. in a suitable solvent allow acetylene and an alkali metal, especially potassium, sodium or lithium, to act on the 17-ketone in a suitable solvent in the presence of an alcohol or in the presence of ammonia. The alkali metal can also be brought into effect in the form of e.g. methyl or butyllithium. Dialkyl ether, tetrahydrofuran, dioxane, benzene and toluene are particularly suitable as solvents. The 17-ethynyl-17-hydroxy compounds can be hydrated in alcoholic solution under mercury catalysis to the 17-acetyl-17-hydroxy compounds (Chem. Ber. 111 (1978) 3086 - 3093). ;The introduction of 3-hydroxypropane, respectively 3-hydroxypropene in the 17-position occurs by reaction of the 17-ketone with metalized derivatives of propargyl alcohol, e.g. with 1-lithium-3-tetrahydropyran-2'-yloxy-propyn-1, to the 17-(3-hydroxy-1-propynyl)-17-hydroxy compounds, which are then hydrogenated to 17-(3-hydroxypropyl-, respectively 3 -hydroxypropenyl)-17-hydroxy compounds. The hydrogenation must be carried out under conditions which only allow attack on the C-C triple bond without desaturating the tetrasubstituted 9(10) double bond. Introduction of the homologous hydroxyalkane and hydroxyalkene groups of general formula -CH=CH-(CH2)n0H or -CH2~CH2-(CH2)n0H occurs in a similar way with homologues of propargyl alcohol. This happens e.g. by hydrogenation at room temperature and normal pressure in solvents such as methanol, ethanol, propanol, tetrahydrofuran (THF) or acetic acid with the addition of noble metal catalysts such as platinum or palladium. ;The connection with the Z-configured double bond in the hydroxypropenyl group occurs by hydrogenation of the acetylenic triple bond with a deactivated noble metal catalyst (J. Fried, J.A. Edwards: Organic Reactions in Steroid Chemistry, Van Nostrand Reinhold Company 1972, page 134, and H.O. House: Modern Synthetic Reactions 1972, page 19). Deactivated noble metal catalysts include, for example, 10% palladium on barium sulphate in the presence of an amine or 5% palladium on calcium carbonate with the addition of lead(II) acetate. The hydrogenation is interrupted after absorption of an equivalent of hydrogen. The connection with the E-configured double bond in the hydroxypropenyl group is formed by reduction of the acetylenic triple bond in a manner known per se. In the literature, a whole series of methods for the transfer of alkynes to trans-olefins are described, for example by reduction with sodium in liquid ammonia (J. Am." Chem. Soc. 6_3 (1941) 216), with sodium amide in liquid ammonia ( J. Chem. Soc. 1955, 3558), with lithium in low molecular weight amines (J. Am. Chem. Soc. Il (1955) 3378), with boranes (J. Am. Chem. Soc. 93. ;(1971) 3395 and 9J (1971) 6560), with diisobutylaluminum hydride and methyllithium (J. Am. Chem. Soc. 8j) (1967) 5085) and especially with lithium aluminum hydride/alcoholate (J. Am. Chem. Soc. 89 (1967) 4245). Another possibility is the reduction of the triple bond with chromium(II) sulfate in the presence of water or dimethylformamide in a weakly acidic environment (J. Am. Chem. Soc. 8j> ;(1964) 4358) as well as usually the reduction by the action of the transition metal compounds under change of the oxidation step. The build-up of the 17-cyanmethyl side chain takes place in a manner known per se from the 17-ketone with the general formula III, e.g. over the 17-spiroepoxide o g cleavage of the spiroepoxide with HCN according to Z. Chem. 18 (1978) 259 - 260. Introduction of the cyanalkane side chain -(CH2)n~CH2CN with n = 1 - 3 takes place, for example, by addition of Li-(CH2)n~CH2CN to the 17-ketone. ;Also the introduction of the 17-hydroxyacetyl side chain takes place in a manner known per se, for example according to that in J. Org. Chem. 4_7 (1982), 2993 - 2995, described method. Free hydroxy groups in the 17-position can be esterified in a known manner. ;After reaction (nucleophilic addition) of the 17-ketone, the compounds of formula III are treated for water splitting to form the 4(5) double bond and for simultaneous ketal splitting and removal of any further acid-cleavable protective groups with acid or another acidic ion exchanger. The acid treatment takes place in a manner known per se as the compound of formula III, which contains a 3-ketal group and a 5a-hydroxy group and an optionally O-protected 17-(3-hydroxypropyl) group, is dissolved in a water-miscible solvent, such as aqueous methanol, ethanol or acetone, and allowing catalytic amounts of mineral or sulphonic acid, such as hydrochloric acid, sulfuric acid, phosphoric acid, perchloric acid or p-toluenesulphonic acid or an organic acid, such as acetic acid, to act for a long time on the solution until water is split off and the protecting groups are removed. The reaction, which proceeds best at temperatures from 0 to 100°C, can also be carried out with an acidic ion exchanger. The progress of the turnover can be followed with analytical methods, e.g. by thin-layer chromatography on withdrawn samples. ;Example 1 ;a) A solution of 2.0 g of 11(3-(4-dimethylaminophenyl)-3, 3-(2,2-dimethylpropane-1,3-dioxy)-5a-hydroxy-9(10)- estren-17-one; (m.p. 143-145°C) in 300 ml of absolute tetrahydrofuran (THF) is irradiated for 16 minutes at 25°C with a Hg high-pressure lamp (Philips HPK 125, immersion lamp, quartz glass reactor).
