The novel process of the invention for the preparation of the compounds of the formula ##STR27## wherein R.sub.1, R.sub.2 and X have the above definition and R.sub.1 ' and R.sub.1 " are each alkyl or one is hydrogen and the other is alkyl or each are --CN or one is alkyl and the other is --CN comprises reacting a compound of the formula ##STR28## wherein R.sub.1, R.sub.2 and X have the above definitions after optionally reacting the same with a protective agent for functional groups with a strong base and/or an alkyl halide or tosyl cyanide or with an alkyl halide and then tosyl cyanide. followed by removal of any protective groups, if necessary.
The process for the preparation of compounds of the formula ##STR29## corresponding to the formula ##STR30## comprises reacting a compound of formula II with a reducing agent to obtain a compound of the formula ##STR31## and reacting the latter with an aromatization acid agent to obtain the compound of formula I.sub.B.
The process for the preparation of compounds of the formula ##STR32## wherein Re, R.sub.1, R.sub.2 and X have the above definitions comprises reacting a compound of formula II with an aromatization agent which is then saponified and optionally reacted with an alkylation agent or an acylation agent.
The process for the preparation of a compound of the formula ##STR33## wherein R.sub.1, R.sub.2 and X have the above definitions comprises reacting a compound of formula II with a reducing agent.
The process for the preparation of a compound of the formula ##STR34## wherein Ra, R.sub.1, R.sub.2 and X have the above definitions comprises reacting a compound of formula II with a formylation agent to obtain a compound of the formula ##STR35## and reacting the latter with an acylation agent or an amine of the formula ##STR36## wherein R.sub.a ' and R.sub.a " have the above definitions.
The process for the preparation of a compound of the formula ##STR37## wherein R.sub.1, R.sub.2 and X have the above definitions comprises reacting a compound of formula III with hydroxylamine.
The process for the preparation of a compound of the formula ##STR38## wherein R.sub.1, R.sub.2 and X have the above definitions and R.sub.f is hydrogen or alkyl comprises reacting a compound of formula I.sub.E with a base to obtain the compound of formula I.sub.A ' wherein R.sub.f is hydrogen and if desired, reacting the latter with a strong base and an alkyl halide to obtain the compound of formula I.sub.A ' wherein R.sub.f is alkyl.
When the compounds of formula II contain one or more groups capable of reacting with a reactant such as an alkyl halide, the groups preferably are protected with a group known in the literature. This is particularly important when the group ##STR39## contains a 17.beta.-ol and this group is preferably protected by tetrahydropyranyl by reacting the compound of formula II with dihydropyran.
The strong bases used are preferably alkali metal alcoholates such as potassium tert.-butylate but equally useful are alkali metal amides such as sodium amide or lithium amide prepared in situ. The alkyle halide is preferably an iodide such as methyl iodide and if gem dialkylation in the 2-positions is desired, at least two equivalents of the strong base are used and the reaction is effected in an excess of alkyl iodide. Monoalkylation is obtained when only one equivalent of the strong base is used. Generally, the .alpha.- and .beta.-isomers may be separated by conventional techniques such as chromatography.
The addition of two cyano groups in the 2-position is effected with tosyl cyanide whose preparation is described in Chem. Com., 1968, p. 440 and is used as in Tetrahedron Letters No. 50 (1981), p. 5011. The addition of an alkyl halide and then tosyl cyanide yields the compounds wherein one of R.sub.1 ' and R.sub.1 " is alkyl and the other is --CN and may be effected under the preceding conditions.
The eventual removal of the protective groups may be effected by the classical methods for instance, acid hydrolysis, preferably hydrochloric acid may be used to remove the tetrahydropyranyl group.
The reducing agent to prepare the compound of formula II.sub.1 is preferably an alkali metal borohydride such as sodium borohydride and the reaction is preferably effected in an alkanol such as methanol or ethanol. The armoatization agent for the preparation of compounds of formula I.sub.B.sbsb.1 is preferably an acyl halide such as acetyl bromide or acetic anhydride or a mixture thereof.
The preferred saponification agent is an alkali metal base such as sodium hydroxide or potassium hydroxide, sodium amide, potassium tert.-butylate or lithium acetylide in ethylenediamine. The reaction is preferably effected in a lower alkanol such as methanol or ethanol.
Depending on the conditions used and for example if the compound contains a group such as ##STR40## with a reactive group like 17.beta.-ol, a partial acetylation of this group will occur resulting in a 17.beta.-ol product containing a variable percentage of 17.beta.-acetyloxy product and the two can be separated by the usual methods such as chromatography. When the starting compound of formula II contains a 17-one group in the pentagonal ring, it can be reduced with sodium borohydride for example.
The eventual alkylation can be effected by usual methods and the preferred alkylating agent is an alkyl halide such as alkyl iodide or an alkylsulfate, preferably methyl sulfate. The acylation may also be effected by known methods and is usually effected with an acyl halide. The reducing agent used to form the compounds of formula I.sub.C are preferably an alkali metal in liquid ammonia, preferably lithium but sodium is also useful.
Depending upon the amount of metal used, other portions of the molecule may be effected and for example, this is the case when the compound has the group ##STR41## containing a 17.alpha.-acetylenic group such as propynyl. The use of two moles of alkali metal results in a practically selective reduction of a 3-keto-.DELTA..sup.4,9 -steroid into a 3-keto-.DELTA..sup.5(10) -steroid. If a supplemental amount of reducing agent is used, there is simultaneously obtained a reduction of an acetylenic group into a trans olefin group, i.e. a 17-prop-1-ynyl into a 17.alpha.-prop-1-enyl. The separation of the two products may be effected by classical methods such as chromatography.
The formylation of the compounds of formula II is effected under known conditions such as by reaction with a formate such as alkyl formates, i.e. ethyl formate, in the presence of a strong base such as sodium hydride and the acylation of the compound of formula III is effected under known conditions as well. Preferably, the acylating agent is an acid anhydride or acid halide such as acetyl chloride and the reaction is effected in the presence of an acid receptor such as pyridine.
The reaction with an amine of the formula ##STR42## is effected under known conditions, preferably with heating. The reaction of the compound of formula III with hydroxylamine which is preferably in the form of an acid salt such as its hydrochloride is effected in a refluxing alkanol such as tert.-butanol. The hydrolysis of the compounds of formula I.sub.E is preferably effected with a base such as sodium hydroxide or potassium hydroxide, preferably in methanol. The alkylation of the compounds of formula I.sub.A ' when R.sub.f is hydrogen is effected under the usual conditions indicated above.
In a preferred mode of the invention, the starting materials of formula II have the group ##STR43## which is ##STR44## wherein R.sub.2 is methyl, R.sub.3 is --OH or ##STR45## and AlK.sub.9 is alkyl of 1 to 4 carbon atoms, R.sub.4 is alkenyl or alkynyl of 2 to 4 carbon atoms and R.sub.1 is ##STR46## or alkoxyphenyl wherein the alkyl has 1 to 4 carbon atoms and AlK.sub.11 and AlK.sub.12 are alkyl of 1 to 4 carbon atoms.
The novel process of the invention for the preparation of compounds of formula II comprises reacting a compound of the formula ##STR47## wherein K is a ketone blocked in the form of a ketal, thioketal, oxime or methyloxime and R.sub.1, R.sub.2 and X have the above definitions with a dehydration agent capable of freeing the ketone group to form a compound of the formula ##STR48##
The process of the invention is particularly useful for forming products of formula I' wherein X form a pentagonal ring of the formula ##STR49## wherein R.sub.2, R.sub.3, R.sub.4, Y and the dotted line in the 16,17-position have the above definition.
In a preferred mode of the process of the invention, the dehydration agent capable of freeing the ketone group is a sulfonic acid resin in the acid form such as a commercial sulfonic acid resin based on polystyrene or a styrene-divinylbenzene polymer but equally useful are inorganic acids such as sulfuric acid or hydrochloric acid in a lower alkanol or perchloric acid in acetic acid or a sulfonic acid such as p-toluene sulfonic acid.
It goes without saying that when one of R.sub.3 or R.sub.4 in the compounds of formula II obtained above is --OH, the compounds of formula II may be reacted with an etherification agent or an esterification agent which is one of those discussed above.

The novel antiglucocorticoid compositions of the invention are comprised of an antiglucocorticoidally effective amount of at least one compound of formula I and its non-toxic, pharmaceutically acceptable acid addition salts and an inert pharmaceutical carrier. The compositions may be in the form of tablets, dragees, gelules, granules, suppositories, ovules, injectable solutions or suspensions, pommades, creams and gels prepared in the usual fashion.
Examples of suitable excipients are talc, arabic gum, lactose, starch, magnesium stearate, cacao butter, aqueous and non-aqueous vehicles, fatty bodies of animal or vegetable origin, paraffinic derivatives, glycols, diverse wetting agents, dispersants and emulsifiers and preservatives.
The compositions are useful to principally counter effect secondary effects of glucocorticoids and are useful for the treatment of troubles due to a hypersecretion of glucocorticoids, especially against aging in general and especially against hypertension, atherosclerosis, osteoporosis, diabetics, obesity as well as immuno-suppressive effects and insomnia.
The study of the products on hormonal receptors shows that they possess progestomimetic or antiprogestomimetic activity or androgen or antiandrogen activity. The compounds of formula I which possess antiprogestomimetic activity are useful as original contraceptives or as interruption of pregnancy agents. They may also be useful for inducing regular cycles in females and more generally in warm-blooded females.
The products may be administered during periods or when progesterone discharges an essential physiological role which is notably during the luteal phase of the cycle at the moment of nidation or implantation of the embryo and during the pregnancy. One method of contraception of the invention consists of administering to the female at least one of the products of formula I or its salts 1 to 5 days before the end of the cycle. The products are preferably administered orally or in the vagina but may also be administered parenterally or endonasally.
The compounds of formula I possessing antiprogestomimetic activity are equally useful against hormonal irregularities and by other means they present an interest in the treatment of hormonodependent tumors. Their action against hypophysial secretions make the compounds useful in menopause.
The compounds are equally useful for the synchronization of estrus in larger animals such as bovines and sheep and are useful for controlling the fertility of household pets such as cats and dogs.
Certain compounds of formula I also present progestomimetic properties and are useful for the treatment of amenorrhea, of dysmenorrhea and luteal insufficiencies.
The compounds of formula I possessing antiandrogenic activity are useful in the treatment of hypertrophies and prostate cancer, of hyperandrogenia, of anemia, hirsutism and of acne as well as male contraception.
Certain of the compounds of formula I possess estrogenic properties and are useful for the treatment of troubles due to a hypofolliculinia such as amenorrhea, dysmenorrhea, repeated abortions, premenstrual troubles as well as for the treatment of menopause.
Certain of the compounds of formula I possess antiestrogenic properties and are useful for the treatment of mammalogy carcinoma and its meta stases.

The novel method of the invention for inducing antiglucocorticoid activity in warm-blooded animals, including humans, comprises administering to warm-blooded animals an antiglucocorticoidally effective amount of at least one compound of formula I and their non-toxic, pharmaceutically acceptable acid addition salts. The compounds may be administered orally, rectally, parenterally or topically and the usual daily dose is 0.15 to 0.150 mg/kg depending upon the compound, the condition treated and the method of treatment.
The antiprogestomimetic compositions of the invention contain a physiologically active quantity of at least one product of formula I and its pharmaceutically acceptable acid addition salts as antiprogestomimetics.
These compositions may be adminstered via the digestive tract, parenterally or locally, particularly in the vagina or via the endonasal route. They may be in the form of a simple tablet or lozenges, gelatin capsules, granulated, suppositories, ovules, injectable preparations, ointments, creams or gels which are prepared according to the usual methods.
Excipients which may be employed are talc, gum arabic, lactose starch, magnesium stearate, cocoa butter, animal and vegetable fats, paraffin derivatives, glycols, various wetting agents, dispersants, emulsifiers and preservatives.
The antiprogestomimetic compositions of the invention have remarkable properties as may be seen in the pharmacological tests which are described later.
The antiprogestomimetic compositions of the invention are used essentially to induce menses in female warm blooded animals.
The induction of menses during the luteal phase of the cycle and particularly at the end of the luteal phase permits the use of the compositions of the invention as contraceptives.
The antiprogrestomimetic compositions according to the invention may be equally used as agents to interrupt pregnancy since experiments with animals have demonstrated them to be abortive at any period of gestation.
The new method of the invention consists of inducing the menses in warm blooded female animals including women and is characterised in that one administers a quantity of antiprogestomimetic compound which is physiologically active such as a product of formula I.
But it is understood that the essential role of progesterone is assigned during the luteal phase of the cycle at the moment of implantation of the embryo and during pregnancy.
The use of an antiprogestomimetic as an inducer of menstruation has been proposed, for example, in the tenth World Health Organization report page 80 and later in Chemtech, September 1977 page 566.
The method of utilization of this product is equally suggested as "post-coital and once-a-month drugs" in the report in WHO and in the expression "when taken monthly . . . will induce menstruation" in the Chemtech article.
Meanwhile before the products of formula I, no product having the required pharmacological properties for such a utilization had been synthesized.
The method of contraception according to the invention consists of administring to the woman about 10 mg to 1 gram of the product for 1 to 5 days preferably at the end of the menstrual cycle. Preferably one takes about 25 to 200 mg of the product per day.
Preferably the product is adminstered orally. Administration of the product via the vagina is equally suitable.
The method of using the products of the invention to interrupt pregnancy consists in administering to warm blooded females at least a physiolgically active amount of the product of formula I.
One administers an amount on the order of about 50 mg to 1 gram per day of the product for 1 to 5 days toward the end of the menstrual cycle. Preferably 200 mg to about 500 mg is used in women.
The preferred manner of administration of this product is orally or via the vagina.
The products of formula I can be used in synchronizing the fertile periods of animals particularly cattle and sheep. They can alsobe used to control the fertility of pets like dogs or cats.
Finally, the products of formula I, which have anti-androgen activity can be used for human contraception.
The compounds of formula A and especially of formula A' used to prepare the compounds of formula B or B" are generally known compounds which can be prepared by reacting the corresponding .DELTA..sup.5(10),9(11) steroids with an epoxidation agent selective for the 5(10) double bond, for example with hydrogen peroxide in the presence of hexachloroacetone or hexafluoroacetone as described in French patent No. 2,423,486. The new compound, 3,3-[1,2-ethanediyl-bisoxy]-17.alpha.-(prop-1-yny)-5.alpha.,10.alpha.-epoxy-.DELTA..sup.9(11) -estrene-17.beta.-ol is prepared in the Example.

PHARMACOLOGICAL STUDY
I. Activity of products on hormonal receptors
A. Mineralcorticoidal receptor of kidneys of the rat
Male Sprague-Dawley EOPS rats weighing 140 to 160 g surrenalectomized 4 to 8 days previously were killed and their kidneys were perfused in situ with 50 ml of a buffer (10 mM of Tris 0.25M of Saccharose and sufficient hydrochloric acid for a pH of 7.4). The kidneys were then removed, decapsulated and homogenized at 0.degree. C. with a polytetrafluoroethylene-glass Potter (1 g of tissue per 3 ml of buffer). The homogenate was centrifuged for 10 minutes at 800 g at 9.degree. C.
After elimination of the fixation of tritiated aldosterone with glucocorticoid receptor, 21-methyl-.DELTA..sup.1,4,6 -pregnatriene-20-yne-11.beta.,17.beta.-diol-3-one fixed only with the glucocorticoid receptor was added to the supernatant at a final concentration of 10.sup.-6 M. The suprenatant was ultracentrifuged at 105,000 g for 60 minutes and 0.degree. C. and aliquoits of the resulting surnageant were incubated at 0.degree. C. with a constant concentration (T) of tritiated aldosterone in the presence of increasing concentrations (0-2500.times.10.sup.-9 M) of cold aldosterone or the cold test product. After a time (t) of incubation, the concentration of tied tritiated aldosterone (B) was measured by the technique of adsoprtion on carbon dextran.
B. Androgen receptor of prostate of rats
Male Sprague-Dawley EPOS rats weighing of 160 to 200 g were castrated and 24 hours later, the animals were killed. The prostates were removed, weighed and homogenized at 0.degree. C. with a polytetrafluoroethylene-glass Potter with a buffered TS solution (Tris, 10 mM, 0.25M Saccharose, HCl-pH of 7.4) using 1 g of tissue per 5 ml of TS. The homogenate was then ultracentrifuged at 105,000 g for 60 minutes at 0.degree. C. and aliquoits of the resulting supernatant were incubated at 0.degree. C. for 2 hours with a constant concentration (T) of product P or 17.alpha.-methyl-.DELTA..sup.4,9,11 -estratriene-17.beta.-ol-3-one in the presence of increasing concentration (0-1,000.times.10.sup.-9 M) of either cold P, cold testosterone or the test compound. The concentration of tied tritiated (B) was measured for each incubate by the technique of adsorption on carbon-dextran.
C. Progestogen receptor of the uterus of rabbits
Immature rabbits weighing about 1 kg received a cutaneous application of 25 .mu.g of estradiol and the animals were killed 5 days later. The uterus was removed, weighed and homogenized at 0.degree. C. with a polytetrafluoroethylene-glass Potter, in a buffered TS solution [Tris 10. mM, 0.25M of saccharose, HCl-pH of 7.4] with 1 g of tissue per 50 ml of TS. The homogenate was ultracentrifuged at 105,000 g for 90 minutes at 0.degree. C. and aliquoits of the resulting supernatant were incubated at 0.degree. C. for a time (t) with a constant concentration (T) of tritiated product R or 17,21-dimethyl-19-nor-.DELTA..sup.4,9 -pregnadiene-3,20-dione in the presence of increasing concentrations (0 to 2500.times.10.sup.-9 M) of either cold R, cold progesterone or cold test compound. The concentration of tied tritiated R (B) was then measured for each incubate by the technique of adsoprtion on carbon-dextran.
D. Gluocorticoid receptor of thymus of rats
Male Sprague-Dawley EPOS rats weighing 160 to 200 g were surrenalectomized and the animals were killed 4 to 8 days later. The thymus were removed and homogenized at 0.degree. C. in a buffered TS solution of 10 mM, Tris, 0.25M of Saccharose, 2 mM of dithiothreitol HCl for a pH of 7.4 using a polytetrafluoroethylene-glass Potter at a rate of 1 g of tissue per 10 ml of TS. The homogenate was ultracentrifuged at 105,000 g for 90 minutes at 0.degree. C. and aliquoits of the resulting surnageant were incubated at 0.degree. C. for a time (t) with a constant concentration (T) of tritiated dexamethasone in the presence of an increasing concentration (0 to 2500.times.10.sup.-9 M) of either cold dexamethasone or cold test product. The concentration of tied tritiated dexamethasone (B) was measured for each incubate by the adsorption on carbon-dextran technique.
E. Estrogen receptor of uterus of mice
Immature female mice 18 to 21 days old were killed and the uterus were removed and homogenized at 0.degree. C. with a polytetrafluoroethylene-glass Potter in a buffered TS solution consisting of 10 mM, Tris, 0125M Saccharose, HCl for a pH of 7.4 at a rate of 1 g of tissue per 25 ml of TS. The homogenate was then ultracentrigued at 105,000 g for 90 minutes at 0.degree. C. and aliquoits of the resulting tritiated were incubated at 0.degree. C. for a time (t) with a constant concentration (T) of tritiated estradiol in the presence of increasing concentrations (0 to 1000.times.10.sup.-9 M) of either cold estradiol or cold test compound. The concentration of tied tritiated estradiol (B) was measured for each incubate by the technique of adsorption on carbon-dextran.
The calculation of the relative affinity of concentration (ARL) was identical for all of the above receptor tests. One traced the following two curves: the percentage of tied tritiated hormone B/T as a function of the logarithm of the cold hormone concentration and B/T as a function of the logarithm of the concentration of the cold test product. One determined the line of the equation. ##EQU1##
B/T max. is the percentage of tied tritiated hormone for an incubation of the hormone at concentration T B/T min. is the percentage of tied tritiated hormone for an incubation of the tritiated hormone at a concentration (T) in the presence of a large excess of cold hormone (2500.times.10.sup.-9 M).
The intersection of the I.sub.50 line and the curves permits one to determine the concentrations of the cold hormone of the reference (CH) and the cold test compound (CX) which inhibit by 50% the tieing of tritiated hormone with the receptor. The relative affinity of tieing (ARL) of the test product was determined by the equation: ##EQU2## The results are reported in the following Table.

CONCLUSION
The tested compounds and especially those of Examples 2, 5,19,25,31,32 and 37 present a very remarkable affinity for glucocorticoid and progestogen receptors as well as a slightly moderate affinity for androgen receptors. These results lead to the conclusion that the products do not have any mineralcorticoid and estrogen receptors and present an agonist or antagonistic activity to glucocorticoids, progestogens and androgens. Moreover, the products of Examples 13 and 14 present an agonist or antagonistic activity to estrogens.
II. Anti-inflammatory Activity
The anti-inflammatory activity of the compound of Example 4 was determined by the classical granuloma test by a modification of the Meier et al test [Experientia, Vol. 6 (1950), p. 469] in which normal female Wistar rats weighing 100 to 110 g received an implantation of 2 pellets of cotton weighing 10 mg each under the thorax skin. The subcutaneous treatment which began immediately after the implantation for 2 days was 2 injections per day. 16 hours after the last injection, the animals were killed and the pellets together with the granuloma tissue formed were weighed in the fresh state and after 16 hours at 60.degree. C. The weight of the granuloma was obtained by subtracting the initial weight of the cotton. The thymus was also removed and weighed to determine the thymolytic activity of the test product.
At a subcutaneous dose of 50 mg/kg, the product of Example 19 did not show any glucocorticoidal anti-inflammatory activity or thymolytic activity.
III. Antiglucocorticoidal Activity
The test used was that of Dausse et al [Molecular Pharmacology, Vol. 13 (1977), p. 948-955] entitled "The relationship between glucocorticoid structure and effects upon thymocytes" for mice thymocytes. The thymocytes of surrenalectomized rats were incubated at 37.degree. C. for 3 hours in a nutritive medium containing 5.times.10.sup.-8 M of dexamethasone in the presence or absence of the test compound at different concentrations. Tritiated uridine was added and incubation was continued for one hour. The incubates were cooled and treated with a 5% trifluoroacetic acid solution and the mixture was filtered with Whatman GF/A paper. The filter was washed 3 times with a 5% trifluoroacetic acid solution and retained radioactivity on the filter was determined. Glucocorticoids and especially dexamethasone provoked a lessening of incorporation of tritiated uridine and the tested compounds, especially those of Examples 1,2,5,10,19,21,23,25,26,29,31,35 and 37 opposed this effect as can be seen from the following Table.

CONCLUSION
The products of the invention used alone do not provoke any effect of the glucocorticoid type at doses provoking an anti agonist effect and the tested products present a very remarkable antiglucocorticoid activity and are devoid of any glucocorticoid activity.
