A stereoselective and synthetically useful rearrangement reaction of 5α,8α‐bridged 9,11α‐epoxy steroids induced by boron trifluoride−diethyl ether is presented, in the preparation of a new class of 5α,9α‐bridged 11α‐hydroxy steroid derivatives in high yields. Lactones were prepared from several of the rearranged 11α‐hydroxy compounds. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
