Two 17-hydroxy-9(105)-abeo-estr-4-ene-3,10-diones

Two 17-hydroxy-9(105)-abeo-estr-4-ene-3,10-diones (5S,9S,17S)-17-Hydroxy-9(105)-abeo-estr-4-ene-3,10-dione, C18H26O3, (II), and (5R,9R,17S)-17-hydroxy-9(105)-abeo-estr-4-ene-3,10-dione, C18H26O3, (III), are equimolecular products of the FeII-induced transposition of 10-hydroperoxy-17-hydroxyestr-4-en-3-one, (I). With respect to reagent molecules, the configuration at C9 is retained for (II) while it is inverted in (III). The conformations of the five- and six-membered rings are compared. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Crystallographica Section C: Crystal Structure Communications International Union of Crystallography
