Process for the preparation of 9(11)-dehydro steroids |
| abstract |
9(11)-dehydroandrostanes and 9(11)-dehydropregnanes are prepared by dehydrating the corresponding 9-alpha-hydroxy steroid in the presence of a Lewis acid. The corresponding 8(9)-dehydro-isomer was not detectable. The resulting products are valuable intermediates in steroid synthesis especially in the preparation of corticosteroids.n[EP0294911A1] |
