11-Oxachlormadinone acetate (17-acetoxy-6-chloro-11-oxapregna-4, 6-diene-3, 20-dione) and 2, 11-dioxachlor-madinone acetate (17-acetoxy-6-chloro-2, 11-dioxapregna-4, 6-diene3, 20-dione) were prepared as potential antiandrogenic agnets. The effect of the latter compound on antiandrogenic activity when tested in the castrated rat was shown to be more potent than that of the parent compound, chlormadinone acetate.
