11β-Hy­droxy­medroxyprogesterone

The title compound, C22H32O4, a fungal-transformed metabolite of medroxyprogesterone, comprises one cyclo­hexa­none ring, two cyclo­hexane rings and one cyclo­pentane ring fused together. The cyclo­hexa­none ring has a half-chair conformation, while the cyclo­hexane rings possess chair conformations and the cyclo­pentane ring has a twisted conformation on the fused C—C bond. In the crystal, mol­ecules are linked by strong O—H⋯O and also C—H⋯O hydrogen bonds, creating a two-dimensional network parallel to (10-1).
