A new backbone rearrangement is observed in A/B cis methyl lithocholate derivatives. It is initiated from the C-3 carbon either by dehalogenation of the chloroesters 1 by AgSbFg6 or by the action of the triflic anhydride on the si1y1ated ether 2. This rearrangement leads to methyl diacholenate 3 and new lactones in D-homoandrostane series 5 and 6. The differences of behaviour between A/B cis and A/B trans series and the mechanism of rearrangements are discussed.
