| titleOfInvention | PROCEDURE FOR OBTAINING NEW DERIVATIVES OF STEREOID ALCOHOLS AND FOR THEIR APPLICATION IN THE SYNTHESIS OF HORINONES |
| abstract | Procedure for the preparation of new derivatives of steroid alcohols and for their application in the synthesis of hormones characterized in that steroid alcohols are subjected to the action of acetals enolic ethers thio-ketal thio-enolic ethers of ketones and aldehydes or derivatives of ketones and aldehydes that instead of the carbonyl oxygen atom contain two halogen atoms or that instead of the hydroxyl group of the enol form contain one halogen atom and, if applicable, the products obtained (provided that these contain one group in their molecules keto) are subjected to the action of reducing agents and then, if necessary, also to the action of acylating or etherifying agents and, if necessary, the keto group or the aldehyde and, if necessary, the hydroxyl group are removed by hydrolysis from the products obtained. released it becomes the oxo group in a known way. |
