biostudies-literatureUnknown69(Pt 4)Andersson PFThe asymmetric unit of the title compound, C20H18O6 (systematic name: 1β,3β-dihy-droxy-2β-meth-oxyfuro[4',3',2':4,5,6]-18-norandrosta-8,11,13-triene-7,17-dione), a dihydro derivative of the fungal steroid viridin, contains two mol-ecules with similar conformations. The rings bearing the hy-droxy groups adopt boat conformations. The absolute structure was assigned based on the known chirality of a precursor compound. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, generating a three-dimensional network and weak C-H⋯O inter-actions consolidate the packing.Acta crystallographica.
