Process for the preparation of pregnanes |
| abstract |
An improved stereoselective process for the preparation of 6.alpha.-fluoropregnane derivatives of formula (I), comprising the reaction of 3-benzoyloxy-.DELTA.3,5-pregnane derivatives of formula (II), with an electrophilic fluorination agent in a substantially water-free reaction mixture and in the presence of a salt of a strong acid with a nitrogenous base. |
