title: 17β-Hy-droxy-17α-(hy-droxy-meth-yl)estr-4-en-3-one.
abstract: The title compound, C(19)H(28)O(3), the fungal-transformed metabolite of the steroid methyl-oestrenol contains four fused rings A, B, C and D. Ring A adopts a half-chair and the trans-fused rings B and C adopt chair confirmations; the five-membered D ring is folded like an envelope. In the crystal, adjacent mol-ecules are linked by O-H⋯O(carbon-yl) and O-H⋯O(hy-droxy) hydrogen bonds into a layer structure.
