Abstract

The title compound, C22H23FO6, is an unexpected product of the fluorination of podophyllol. The absolute configuration was determined from the known configuration of the synthetic precursor. Non-classical C—H⋯O hydrogen bonds link the mol­ecules in the crystal structure into sheets parallel to (001).

Abstract

In the title compound, C25H23BrN2O4, the seven-membered ring adopts a twisted-boat conformation. The indole ring system is planar within 0.021 (2) Å and the ester group [–C(=O)—O—C–] is almost coplanar with it [dihedral angle = 3.0 (2)°]. The conformation of the ester group is influenced by intramolecular C—H...O interactions. In the crystal structure, molecules are linked into chains along the b axis by C—H...N hydrogen bonds.
