| titleOfInvention | Process for preparing 5ª‡-hydroxy-6ª‰-aminosteroids of the pregnane series |
| abstract | The invention comprises 5a -hydroxy-6b -azido - pregnane - 3,20 - dione, the 3,20-bis-ethyleneketal thereof, 3b ,5a -dihydroxy-6b -azidopregnan-3,20-dione, 5a -hydroxy-6b -aminopregnane-3,20-dione, the 3,20-bis-ethylene ketal thereof, 3b ,5a ,20 - trihydroxy - 6b - aminopregnane, 5a - hydroxy - 6b - acetylaminopregnane - 3,20 - dione, the 3,20 - bis-ethyleneketal thereof and a process for preparing a 5a -hydroxy-6b -amino steroid of the pregnane series which comprises reacting a 5a ,6a -epoxysteroid of the pregnane series with hydrogen azide or an alkali metal azide and reducing the resulting 5a -hydroxy-6b -azido steroid of the pregnane series with a metal hydride. |
