| titleOfInvention | NEW STEROID FROM THE PREGNANE SERIES AND PREPARATION METHOD THEREOF |
| abstract | The invention relates to dimethyl-17 alpha, 21 19-nor-prégnen-5 (10) ol-20 xi one-3. A subject of the invention is also a preparation process, characterized in that one: - subjects to methylation in position 21, by means of a methyl halide, methyl-17 alpha 19-nor-pregnatrien-1 , 3.5 (10) methoxy-3 one-20; - Acts, on the resulting dimethyl-17 alpha, 21 19-nor-pregnatrien-1,2,5 (10) methoxy-one-20, a reducing agent to obtain the dimethyl-17 alpha, 21 19-nor- pregnatrien-1,3,5 (10) 3-methoxy-20-ol xi; and - subjects the latter to the action of lithium in ammonia according to the Birch reaction, to obtain the desired product The product of the invention finds its use in the synthesis of products exhibiting therapeutic activity |
