| titleOfInvention | PROCEDURE FOR THE PREPARATION OF NEW STEROID COMPOUNDS |
| abstract | Procedure for the production of 6-alpha-methyl-17-alpha-hydroxyprogesterone and its esters that present progestative activity higher than that of progesterone both in subcutaneous and oral administration of the general formula ** (See formula) ** in which R is selected from the group consisting of hydrogen and acyl radicals derived from aliphatic and cycloaliphatic carboxylic acids containing up to and even 9 carbon atoms, the process of which comprises transforming Δ5-pregnen-17-alra-ol-320-dione-bis-ethylene glycolcetalo Δ5- pregnen-3-beta17-alpha-diol-20-one-ethylene glycolcetain a mixture of alpha- and beta-56-epoxides separate the 5-alpha-6-alpha-epoxides transform said epoxides from 6-beta-methyl-alepregnan-5 -alpha17-alpha-diol-320-dione and 6-beta-methyl-allopregnan-3-beta5-alpha17-alpha-triol-20-one respectively and transform these compounds into 6-alpha-methyl-17-alpha- hydroxyprogesterone and its esters. |
