Abstract
Process for 21-acetoxylation by means of its 21-diiodated derivatives of high increment to 9-11 20-ceotesteroids of the group of pregnenos and allopregnenes which may also have one or more various substituents, one or more supplementary double bonds, characterized in that iodine is reacted in the presence of calcium chloride and calcium oxide on a high increment to 9-11 20 ketosteroid in solution in an appropriate solvent, the 21-diiodinated derivative is isolated and the latter is treated, in solution in an appropriate solvent, with an alkaline acetate.
