organic compounds
The structure of the title compound, 3α,4α-epoxy-5α-androstan-17-one, C19H28O2, shows evidence of the strain caused by the presence of an epoxy O atom bonded to C3 and C4 in the molecule. Ring A has a sizeable distortion and assumes a conformation intermediate between 10-β-sofa and 1,10-half chair. Ring D has a 14-α-envelope conformation. Cohesion of the crystal is due only to van der Waals interactions and weak intermolecular C—H
O interactions.
