Disse hittil ukjente enoletere har These hitherto unknown enolets have

uventede biologiske egenskaper, som er unexpected biological properties, which are

bedre enn egenskapene til de frie ketoner. better than the properties of the free ketones.

Disse egenskaper beskrives nærmere neden-for. These properties are described in more detail below.

Fremgangsmåten ifølge oppfinnelsen The method according to the invention

er karakterisert ved at man omsetter etylenoleteren av et tilsvarende A4-3-keto-steroid med en alkohol ROH, hvor R har is characterized by reacting the ethylene ether of a corresponding A4-3-keto-steroid with an alcohol ROH, where R has

den ovenfor nevnte betydning i nærvær av en sur katalysator. the above meaning in the presence of an acid catalyst.

Den sure katalysator, som benyttes ved ombytningsreaksjonen, kan være en av de til dannelse av enoletere vanlig anvendte syrer, slik som toluensulfonsyre eller en annen syre av samme art, slik som benzensulfonsyre eller naftalensulfonsyrer eller antrakinonsulfonsyrer. Som katalysator kan også anvendes en Lewissyre, slik som SnCl4, SbCl5 eller salter av organiske baser med mineralsyrer, slik som pyridinhydro-klorid. The acid catalyst, which is used in the exchange reaction, can be one of the acids commonly used for the formation of enol ethers, such as toluenesulfonic acid or another acid of the same kind, such as benzenesulfonic acid or naphthalene sulfonic acids or anthraquinonesulfonic acids. A Lewis acid, such as SnCl4, SbCl5 or salts of organic bases with mineral acids, such as pyridine hydrochloride, can also be used as a catalyst.

Ombytningsreaksjonen forløper i al-minnelighet i et organisk fortrinnsvis ikke polart oppløsningsmiddel. Det anvendes fortrinnsvis oppløsningsmidler som benzen, cykloheksan, isooktan eller tetrahydrofuran. Også halogenholdige oppløsningsmid-ler, slik som etylenbromid, kloroform og tetrakloretan kan anvendes alene eller i blanding med et av de ovenfor nevnte opp-løsningsmidler. The exchange reaction generally takes place in an organic, preferably non-polar, solvent. Solvents such as benzene, cyclohexane, isooctane or tetrahydrofuran are preferably used. Halogen-containing solvents, such as ethylene bromide, chloroform and tetrachloroethane can also be used alone or in admixture with one of the above-mentioned solvents.

Reaksjonsblandingen som består av etylenoleteren av 3-keto-A4-steroidet, som er suspendert eller oppløst i et av den ovenfor nevnte oppløsningsmidler av alkoholen og som velges til utførelse av ombytningsreaksjonen, og av den sure katalysator, bringes til kokning i en kolbe forsynt med stigende eller fallende kjøler. Hvis blandin-gen destilleres en viss tid, fjernes all etanolen som danner seg under ombytningsreaksjonen ved medrivning eller ved azeo-trbpisk blanding med oppløsningsmidlet. Varigheten av destillasjonen avhenger na-turligvis av volumet av det anvendte opp-løsningsmiddel og av mengden av den om-satte etylenoleter. The reaction mixture consisting of the ethylene ol ether of the 3-keto-A4 steroid, which is suspended or dissolved in one of the above-mentioned solvents of the alcohol and which is chosen to carry out the exchange reaction, and of the acidic catalyst, is brought to boiling in a flask provided with rising or falling cooler. If the mixture is distilled for a certain time, all the ethanol formed during the exchange reaction is removed by entrainment or by azeotropic mixing with the solvent. The duration of the distillation naturally depends on the volume of the solvent used and on the quantity of the converted ethylene ether.

Minst 2/3 av oppløsningens begynnel-sesvolum skal avdestilleres. Man kan så være sikker på at etanolen er blitt fullkom-men avdestillert fra reaksjonsblandingen. Oppløsningsremanensen gjøres svakt alka-lisk ved tilsetning av en svak organisk base, f. eks. pyridin og konsentreres deretter til et lite volum. Man kan med fordel lette krystallisasjonen av enoleteren i remanensen ved tilsetning av metanol, etanol eller heksan. At least 2/3 of the initial volume of the solution must be distilled off. One can then be sure that the ethanol has been completely distilled from the reaction mixture. The solution residue is made slightly alkaline by adding a weak organic base, e.g. pyridine and then concentrated to a small volume. Crystallization of the enol ether in the residue can be facilitated by adding methanol, ethanol or hexane.

Den som utgangsstoff anvendte etylenoleter fås ved omsetning av et 3-keto-A4-steroid med ortomaursyreetylester. Det er ikke absolutt nødvendig å fremstille etylenoleteren særskilt og derpå etter rensning å underkaste den den ovennevnte ombytningsreaksjon. Reaksjonen kan også utføres i den oppløsning inneholdende etylenoleteren, som fås ved reaksjon mel-lom 3-keto-A4-steroidet og ortomaursyre-etylesteren. I så fall lar man et overskudd av den ønskede alkohol i nærvær av en sur katalysator i et ikke polart oppløsnings-middel innvirke på oppløsningen. Denne reaksjonen gir utbytter av enoleter, som overstiger de som fås, når man går ut fra ren 3-enoletyleter. The ethylene ether used as starting material is obtained by reacting a 3-keto-A4-steroid with ethyl orthoformate. It is not absolutely necessary to prepare the ethylene ether separately and then, after purification, subject it to the above-mentioned exchange reaction. The reaction can also be carried out in the solution containing the ethylene ether, which is obtained by reaction between the 3-keto-A4 steroid and the ethyl orthoformic acid ester. In that case, an excess of the desired alcohol in the presence of an acidic catalyst in a non-polar solvent is allowed to affect the solution. This reaction gives yields of enolets, which exceed those obtained when starting from pure 3-enole ethyl ether.

Enoleterene av progesteron og dennes 17-hydroksy- og acetoksyderivat utmerker seg ved verdifull gestagen virkning, idet de administrert per os er meget virksommere enn de tilsvarende A4-3-ketosteroider og fri for bivirkninger. Især utviser de ingen androgen virkning, ingen follikel-springshindring og fremkaller ingen hyp-nose. The enol ethers of progesterone and its 17-hydroxy and acetoxy derivative are distinguished by their valuable progestogenic effect, as they are much more effective when administered per os than the corresponding A4-3-ketosteroids and free of side effects. In particular, they exhibit no androgenic effect, no follicle-bursting inhibition and induce no hypo-nosis.

For å prøve den gestagene virkning av disse forbindelser i sammenlikning med de tilsvarende A4-3-ketoner ble det anvendt Claubergprøven, og den gestagene virkning betegnes med Mc. Phail indekset (The journal of Physiology, bind 83, 1935, side 145). To test the progestogenic effect of these compounds in comparison with the corresponding A4-3 ketones, the Clauberg test was used, and the progestogenic effect is denoted by Mc. The Phail index (The journal of Physiology, volume 83, 1935, page 145).

Resultatene av forsøkene er sammen-fattet i tabell I og II. The results of the experiments are summarized in Tables I and II.

Resultatene viser at 3-n-amylenoleter og 3-cyklopentylenoleter av progesteron er 10 henholdsvis 7 ganger virksommere enn progesteron, og 3-cyklopentyl- og n-amylenoleter av 17a-acetoksyprogesteron er 10 henholdsvis 4 ganger virksommere enn den tilsvarende A4-3-ketoforbindelse. The results show that 3-n-amylenol ether and 3-cyclopentylenol ether of progesterone are 10 and 7 times more effective than progesterone, and 3-cyclopentyl and n-amylenol ether of 17a-acetoxyprogesterone are 10 and 4 times more effective than the corresponding A4-3-keto compound .

Enoleterene av 17a-etinyl-19-nortesto-steron og deres ester har verdifulle biologiske egenskaper. Farmakologiske forsøk har vist at enolforetringen av 17|3-etinyl-19-nortestosteronet bevirker en fraskillelse av utgangsketonets gestagene og kontra-septive virkning. Især har cyklopentylenoleteren av 17a-etinyl-19-nortestosteronace-tat en forøket antiøstrogen og antikonsep-tionel virkning og en nedsatt progestesjo-nalverdi. The enol ethers of 17α-ethynyl-19-nortestosterone and their esters have valuable biological properties. Pharmacological experiments have shown that the enol esterification of 17|3-ethynyl-19-nortestosterone causes a separation of the starting ketone's progestogenic and contraceptive effects. In particular, the cyclopentylenol ether of 17α-ethynyl-19-nortestosterone acetate has an increased antiestrogenic and contraceptive effect and a reduced progestational value.
