Abstract: The title compound, C22H28O2, was synthesized from 17-ethynylestradiol in 86% yield. The X-ray structure determination shows that, in the steroid nucleus, one of the cyclohexane rings adopts a half-chair conformation and the other shows a chair conformation. The cyclopentane ring adopts an envelope conformation. In the crystal structure, symmetry-related molecules exist as C-HO hydrogen-bonded dimers.
