Abstract: In the title estrane derivative, C20H23BrO2, the five-membered ring adopts a conformation that is intermediate between twist and envelope. The C atom of the formyl group and the bromo function are in close proximity. Close intermolecular BrBr and BrC contacts are observed in the crystal structure.
