The synthesis fo 17a-bromo-6a-inethylprogesterone, from pregnenolone acetate, is reported. The product is a potent luteoid with marked oral activity. In the course of this investigation, a useful x ariation of the synthesis of 6a-methylprogesterone, from pregnenolone, was devised. The rearrangement of a 5p,Bp-epoxide to a 6-ketone, upon chromatography on a l u n~i~l u m oxide "\Voelrn", was observed.
