United States Patent 3,234,093 6-CHLORO-LZa-METHYLENE-A -l7oL-HYDRQXY- PRQGESTERONE COMPQUNDS AND CQM- POSITIONS Rudolfi Wiechert, Berlin-Lichterfelde, Germany, assignor to 'Schering Aktiengesellschaft, Berlin, Germany No Drawing. Filed Apr. 24, 1962, Ser. No. 189,724 Claims priority, application Germany, Apr. 29, 1961, Sch 29,643 The portion of the term of the patent subsequent to Mar. 31, 1981-, has been disclaimed 12 Claims. (Cl. 161-74) The present invention relates to new progestational agents and treatments therewith, and more particularly to new 6-position halogenated l,2a-methylene-A -l7ahyd-roxyprogesterones which have an unusually high proge'stational action, even upon peroral administration, to these new compounds, methods of producing the same, progesta'tional compositions containing the same, and progestational treatments using these compounds.
lt is-a primary object of the present invention to provide a new series of compounds with progestational activity.
It is another object of the present invention to provide 6-position halogenated 1,Zu-methyIene-A -l7a-hydroxyprogesterone esters which have a remarkably high progestational activity.
It is yet another object of the present invention to provide for the production of these new compounds.
The present invention also has as its object the provision of progestational compositions containing the compounds of the present invention as the active ingredient thereof, and also the treatment of patients requiring progestational effect.
Other objects and advantages of the present invention will be apparent from a further reading of the specification and of the appended claims.
With the above and other objects in view, the present invention mainly comprises a compound of the formula:
wherein X is a halogen, and wherein R is selected from the group consisting of hydrogen and acyl wherein acyl is derived from a carboxylic acid.
The esters of the present invention, i.e., compounds of the above formula wherein R is acyl derived from a carboxylic acid, have been found to have a surprisingly high degree of progestational action, which is in many cases equal to and superior to the progestational action of known compounds used for this purpose, and particularly upon peroral administration is in many cases several times greater than the progestational action of known compounds used for this purpose. Accordingly, the most preferred progestational compounds of the present invention are the 6-position halogenated-liar-methylene- 3,Z34,@93 Patented Feb. 8, 1965 ice N-l7whydroxyprogesterone esters of carboxylic acids.
Although the invention is in general applicable to all o-halogenated compounds of the above group, it is most preferred from the point of view of high progestational action that the halogen in the 6-position be chlorine. Thus, for example, although the 6-brominated compounds are also active progestati-onal compounds, the action thereof is considerably less than the 6-chlorinated corresponding compounds.
The present invention is in general applicable to all types of carboxylic acid esters of 6-hal'ogen-l,2a-methylene-A -l7a-hydroxyprogesterone, including aliphatic acid esters, alicyclic acid esters, aromatic acid esters and mixed open chain-cyclic carboxylic acid esters. All of these esters may be produced in analogous manner to the production of the esters of the present invention which will be shown in the examples given below.
The preferred esters from the point of View of the progestational activity of the present invention are the aliphatic carboxylic acid esters of up to 10 carbon atoms, such as the acetate, propionate, valerate, capronate, enanthate, etc. The acetate exhibits a particularly high degree of progestational activity, particularly upon peroral administration, and the higher homologous esters exhibit a similar high degree of progestational activity, which, particularly in the case of peroral administration, is higher than that of known progestational compounds. In the case of the higher homologs, starting with the enanthate, there is in addition a valuable protraction of the p'rogestational activity. Also preferred for the purposes of the present invention are the alicyclic and mixed open chain-cyclic carboxylic' acid esters, such as the cyclopentlypropionate.
The compounds of the present invention may be incorporated into progestational compositions of all type, e.g., for injection purposes, such as by subcutaneous injection, or for peroral administration. Although it is a particular advantage of the present invention that the compounds thereof have a highly superior progestational activity upon peroral administration, it is apparent that this invention should not be limited to the use of the compounds for peroral administration because the compounds can'also be used by injection, by per os administration, for example in the form of suppositories, etc.
In preparing compositions-with the progestational compounds of the present invention, these compounds can be used as active ingredient with any normal pharmaceutical carrier or excipient for administration by injection, for peroral administration in the form of tablets, dragecs, emulsions, for rectal administration suppositories, etc. Thus, for example, in the manufacture of tablets and dragees the pharmaceutical carriers and excipients would include diluents and absorbents such as amidone, sugar, carbon-ates, kaolin, etc.; agglutinants such as carboxymethyl cellulose, alginates, gums, sorbitol, polyvinylpyrrolidone, pectins, etc.; lubricants such as talc, stearic acid, stearates, etc.; wetting agents such as sorbi't'an, mono-oleate, oleates or ste-arates of triethanolamine, etc.; buffering substances such as calcium salts, glyoocols, mag
esium trisilicate, etc.; coating substances such as gluten, cellulose acetophthalate, methyl phthalate, ethyl phthalate, etc.; carriers and excipients for emulsions, such as polyethylene-glycol, carboxymethyl cellulose, methyl cellulose, sorbitan mono-o leate, interesterified oils, etc.; and carriers and excipien-ts for suppositories such as cocoa butter, ynthetic semi-glycerides, etc.
As indicated above, a particular advantage of the adequate. positive Clauberg test on infantile rabbits.
present invention is that the composition thereof can: be administered in the form of capsules, tablets, dragees,
marked superior activity of the compound of the' present invention:
The preferred daily dose of the pro- The compounds of the present invention are produced 1 by introducing a halogen atom into the 6-position of. the; chosen L'Za-methylene-A -l7u-hydroxyprogesterone ester. In accordance with the method of the present invention the LZa-rmethylene-A -l7a-hydroxyprogesterone ester is first converted in known manner, preferably by means of pere carboxylic acids, particularly perbenzoic acid, into the: corresponding 6,7a-epoxide, which is then treated with the hydrohalic acid, preferably in glacial acetic acid solution, whereby in a single operation the cyclopropane ring is opened with the formation of a lot-halogen methyl group, and the epoxy ring is opened with the splitting-off ofwater and the formation of the 6-halogen-Ni-grouping.
The lot-halogen. methyl group of the. reaction product is then subsequently re-converted into the 1,2wmethylene group, preferably by means of organic bases, particularly collidine. This method is illustrated by the following general equations:

The starting compounds for the method of the present invention may be produced in accordance with the methods shown in German Patent No. 1,072,991, German Patent No. 1,096,353, and US. patent application Serial No. 60,812, now US.
