Summary It has been shown that while the bromination of A1-androsten-17-ol-3-one 17- hexahydrobenzoate (I) proceeded rapidly with the formation of the corresponding A'-2- bromo-3-ketone 11, the latter reacted only slowly with bromine to form A'-2, 4- dibromoandrosten-17-01-3-one 17-hexahydrobenzoate (111). The dibromo compound was dehydrobrominated with collidine yielding a 2-bromo-l14-dienone IV, which underwent ...
