| titleOfInvention | PROCESS FOR PREPARING 11 BETA-ARYL SUBSITUTED 17 BETA-ALKOXY-17 ALPHA -ALKOXYMETHYL-ESTRA-4,9-DIEN-3-ONES |
| abstract | The invention relates to a chemical-synthetic process for the preparation of 11b-aryl-substituted compounds which are of interest as potential agents for the control of fertility in the pharmaceutical industry. In the process, * with bases in the 17b-alkoxides are converted, which are reacted with alkyl halides to 17b ethers and then epoxidized selectively in the * with H2O2 to the 5a, 10a epoxides, then with p-substituted Arylmagnesiumbromiden in the presence of copper I salts are opened to 11b-aryl-substituted 5α-hydroxysteroids and converted to the 11b-aryl-substituted * under acidic conditions. {Estrane; 11b-aryl substituted * 17b-ethers; Antigestagens; Drug} |
