The asymmetric unit of the title compound, C20H18O6 (systematic name: 1,3-dihydroxy-2-methoxyfuro[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 molecules with similar conformations. The rings bearing the hydroxy groups adopt boat conformations. The absolute structure was assigned based on the known chirality of a precursor compound. In the crystal, molecules are linked by O-HO hydrogen bonds, generating a three-dimensional network and weak C-HO interactions consolidate the packing.
