PRECISION OF DISCLOSURE: The invention relates to a process for preparing compounds of formula (I '): (I ') where R1 is an organic radical having from 1 to 18 atoms of carbon and containing nitrogen, phosphorus or silicon, R2 a hydrocarbon radical having from 1 to 8 carbon atoms, X the remainder of a pentagonal or hexagonal cycle possibly substituted and unsaturated, C = Has a free or blocked oxo group or a group , C = N-OH, C = NO-alc3 or CH2 (alc1, alc2, alc3 = alkyl (1-8c) or aralcoyl (7-15c)) and B and C form a double bond or an epoxy bridge. The compounds of formula (I ') thus obtained are endowed in particular with anti-glucocorticoid properties. |
