This invention relates to a process for the preparation of steroids of general formula not described in the literature. :: v-BASIS 1 V I where dashed line indicates a possible double bond; X is hydrogen, fluorine or methyl; Y is hydrogen or lower alkanoyloxy, Z is hydrogen or methyl, V is methylene or ethylidene, R, is lower alkyl or an oxygen-interrupted alkyl group is hydrogen or lower alkyl, or Cc and R are three or tetramethylene groups if Y is alkanoyl-oxylate pharmacological activity. A known method for producing steroid-type acetals is that the alcohol is reacted with an aliphatic acetal in the presence of an acid catalyst l. The purpose of the invention is a method for producing new pharmacologically active steroids of general formula 1, based on the use of a known reaction. The objective is achieved by a method for producing steroids of the general formula I, in that the steroid of the general formula COCET; l-OH g, where V, X, y, Z are the above values, W is a carbonyl group, if the double bond is in position 4 , 5 and optionally 7,8, or W group of the formula D b and the alkanoyloxy group, if the double bond is in the 5.7 position, is reacted with acetal of the general formula III (RjCHCOR), where R and Kj have the above values or vinyl ester of general formula IV "4CH CHOR, where R- is as defined above, and R is water genus or lower alkyl or together with R - ethylene or trimethylene if Y alkanoyloxy, and in the resulting compound, if necessary oxidized 3 P- alkanoyloxy with simultaneous isomerisation of the double bond D followed by isolation of the desired product. The process is carried out in the presence of acid catalysts such as chloric acid, p-toluenesulfonic acid or phosphorus pentoxide, without a solvent or in an inert solvent, for example, chlorinated hydrocarbons, toluene, ether, tetrahydrofuran, dioxane. The temperature of the process is maintained between and + 50s using compounds of general formula III and from to. case of compounds of General formula IV. Steroids of General Formula I exhibit high anti-inflammatory activity.
