Description
Summary:In the title compound, C27H20BrNO3, the pyrrolidine ring adopts a half-chair conformation, while the other five-membered rings adopt flattened envelope conformations with the spiro C atoms as the flap atoms. An intramolecular C—H...O hydrogen bond occurs, generating an S(6) ring. In the crystal, molecules are connected via weak C—H...O hydrogen bonds, forming chains along the c axis.
