  Process for the production of new 9ss, 10 steroids The invention relates to a process for the production of new 9/3, l. Ox steroids of the formula
EMI1.1
 in which R is a carbonyl group or one of the groups
EMI1.2
 where R 'is hydrogen, an alkyl, cycloalkyl, cycloalkenyl, aralkyl, tetrahydropyranyl or acyl group, X is hydrogen, a halogen atom or a hydroxy or acyloxy group; Y represents hydrogen or OR 'and Z represents hydrogen or a lower alkyl, alkenyl or alkynyl group. or # 6-dehydro derivatives thereof.



   A halogen atom represented by the symbol X is preferably a fluorine atom. Suitable acyl groups are acyl radicals of saturated or unsaturated aliphatic, cycloaliphatic, araliphatic or aromatic carboxylic acids, which preferably contain 1-20 carbon atoms. Examples of such acids are: formic acid, acetic acid, pivalic acid, propionic acid, butyric acid, caproic acid, enanthic acid, oleic acid, palmitic acid, stearic acid, succinic acid, malonic acid, benzoic acid. Other examples of radicals RI are: methyl, ethyl, propyl, tert-butyl, cyclopentyl, cyclohexyl, benzyl, cyclopentene- (1) -yl- and 1'-ethoxy-cyclopentyl.



   Lower alkyl, alkenyl and alkynyl groups represented by the symbol Z preferably contain up to 5 carbon atoms, such as methyl, ethyl, propyl, isopropyl, butyl, isopropyl, butyl, isobutyl, amyl, vinyl, allyl, 1 'and 2 '-Methallyl, ethynyl and propargyl.



   The process according to the invention is characterized in that a 9ss, 10x steroid which corresponds to general formula I but is unsubstituted in the 2-position or an A6 dehydro derivative thereof is treated with lead tetraacetate in glacial acetic acid.



   The new 9ss, 10, x steroids obtainable according to the invention are hormonally or anthihormonally effective.



   They can be used as remedies in the form of pharmaceutical preparations.



   In the following examples the temperatures are given in degrees Celsius.



   Example 1
A solution of 24 g (17ss-acetoxy-9ss, 10α-androst-4-en-3-one in 170 ml of glacial acetic acid was added at room temperature to a solution of 35 g of lead tetraacetate in 420 ml of glacial acetic acid Nitrogen heated to 90, after 3 hours a further 30 g of lead tetraacetate were added and the mixture was stirred for a further 18 hours, after which the reaction mixture was concentrated in vacuo.

   After working up the residue and chromatography on silica gel, 3.2 g of 2α, 17ss-diacetoxy-9ss, 10α-androst-4-en-3-one, melting point: 161-163 C, UV: γ max 243 nm , # = 15,800, [?] D25 = 15 (in dioxane) and 4.5 g 2ss, 17ss-diacetoxy9ss, 10? Androst-4-en-3-one, melting point: 193-195, UV:? max240 nm, # = 15,900, [α] D35 = -135 (in dioxane).
EMI2.1
 R 'denotes hydrogen, an alkyl, cycloalkyl-cycloalkenyl, aralkyl, tetrahydropyranyl or acyl group, X hydrogen, a halogen atom or a hydroxyl or acyloxy group;

   Y represents hydrogen or OR1 and Z represents hydrogen or a lower alkyl, alkenyl or alkynyl group. or A6-dehydro derivatives thereof, characterized in that a 9ss, 10α-steroid which corresponds to the formula I but is unsubstituted in the 2-position or a # 6-dehydro derivative thereof is treated with lead tetraacetate in glacial acetic acid.



   Example 2
A solution of 2.0 g of 9 &, 10a-pregna-4, 6-diene-3, 20-dione and 2.83 g of lead tetraacetate in 60 ml of glacial acetic acid was heated to 80 for 15 hours. The reaction mixture was poured onto ice water and extracted with ether. On chromatography on silica gel with ether-petroleum ether (1: 1) elution, the extracted material gave pure 2ss-acetoxy-9ss, 10α-prena-4, 6-diene-3, 20-dione. Melting point: 185-187 (from acetone-hexane), [α] D25 = -422. UV: # 39max 284 nm / # = 26400.



   Example 3
Analogously to Example 1, 17α-methyl-17ss-aceto-xy-9ss, 10α-andandrosta-4, 6-dien-3-one was converted into 2a 17ss diacetoxy-17α-methyl-9ss, 10α-andandrosta-4 , 6-dien-3-one, melting point: 178-180, UV: dama. 292 nm; e = 26000 and the 2ss isomer, melting point: 177-178, UV: AllaX284 nm, s = 27100, [a] n = -490 (dioxane).
