STEROIDAL 17ALPHA-SILYL ETHERS AND PROCESS TO CORTICOIDS AND PROGESTERONES |
| 摘要 |
17 beta -Cyano-17 alpha -hydroxy steroids (I) are transformed to 17 alpha -halo silyl ethers (II) which are intermediates useful in the production of progesterones (V), 17-hydroxyprogesterones (VI), corticoids (VII) and 21-halo corticoids (III) which can readily be transformed to corticoids (VII). |
