The ring opening of steroidalepoxides are carried out in a regioselective manner using bismuth chloride, ferric chloride, indium chloride, silica supported BiCl3, FeCl3 and InCl3 under mild condition in variable yields. The products obtained were identified by various spectroscopic techniques. The structure of one of the compound has been determined by X-ray diffraction using the direct method and
