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.
