Abstract
The molecular structures of 17αβ-acetoxy-3-methoxy-6-oxa-D-homo-8-isoestra-1,3,5(10)-triene (I) and 17αβ-acetoxy-3-methoxy-4-methyl-6-oxa-D-homo-8-isoestra-1,3,5(10)-triene (II) have been established by X-ray diffraction analysis. The presence of the methyl group at the C(4) atom in compound II leads to slight changes in the conformation of the carbon skeleton of this molecule and the orientation of the methoxy group with respect to the C(2)-C(3) bond.
