专利说明:
This invention relates to a process for the preparation of 17 b-hydroxy-4-androsten-3-ones of the general formula ON not described in the literature. .ieHjU - “% rf PGG n. where hydrogen or an aliphatic acid residue, ime11BP1 to 4 carbon atoms; -D-C- are a group or 5 "with pharmacological activity. The use of the known methylation method of unsaturated ketones with dimethylsulfoxonium methyl in dimethyl sulfoxide 1 allows the preparation of new pharmacologically active steroids. The purpose of the invention is to obtain new pharmacologically active P-oxy-4-androsten-3-ones. A method is proposed for the preparation of 17 | b-hydroxy-4-androsten-3-ones of Formula I, which consists in the fact that 3-keto-4, 6-androst spirolactone of the general formula P / I f where -0-C- has the above values, is treated with lithium aluminum hydride in an aprotic solvent, the 3-keto group is previously protected, methylated with dimethylsulfoxoniummethyl in dimethylsulfoxide and, if necessary, the resulting product is sterilized in the presence of an esterification catalyst, after which the desired products are added. The carbonyl group is preferably protected by ketalization with ethylaglycol in methylene chloride in the presence of three tetro-formate. The reduction with lithium aluminum hydride is preferably carried out in tetrahydrofuran or dioxane at a temperature not higher than room temperature. The methylenating agent is obtained from the trimethyl phosphonic acid and hydride sodium or sodium hydroxide. An acid anhydride or acid halide is used to esterify a hydroxyl group in the presence of a tertiary amine, such as pyridine, collidine, triethylamine, or a strong acid, such as p-toluenesulfonic acid. Compounds of the formula G have an aldosterone antagonist-type action mechanism. Example 1. 12.0 g of J-OKCO-4, 6,15-androstrieno-17 P -1-spiro-5-perhydrofuran-2-one from 60 ml. , methylene chloride is mixed with 36 ml of ethylene glycol, 24 ml of tr.ethyl ether tartaric acid and 120 mg of p-toluenesulfonic acid and stirred for 75 minutes at 0 ° C, diluted with agyr, washed with water, dried and evaporated to dryness in vacuo. 13.5 g of crude 3, 3-ethylenedioxy-4, 6.15-androstrieno-17p1-1 spiro-5-perhydro-Luran-2-one are obtained. 13.5 g of the obtained compound is dissolved in 650 ml of absolute tetrahydrofuran, cooled with an ice bath, mixed with 2.9 g of lithium aluminum hydride and further stirred for 30 minutes while cooling.
