A PROCEDURE FOR THE PREPARATION OF A METHYLENE DERIVATIVE OF THE PREGNANE SERIES |
| abstract |
Preparation process of a methylene derivative of the pregnane series characterized in that a 12-ketosteroid of the pregnane series is transformed by means of a Grignard reagent into a 12-hydroxy 12-methyl derivative and the latter is subjected to the action of dehydrating agents so as to obtain the corresponding steroid 12-methylene. |
