PROCESS FOR CONVERTING 17-KETO-STEROIDS TO 16-BETA-METHYL-17-KETO-STEROIDS |
| 摘要 |
DELTA <4>-3-keto, DELTA <1,4>-3-keto and 3 beta -hydroxy-17-keto-steroids are transformed into the corresponding 16 beta -methyl-17-keto-steroids by activating the C-16 position, metylating, and reacting with a strong base. The C-3 position of the DELTA <4>-3-keto and 3 beta -hydroxy-steroids is protected. |
