Abstract
In the title compound, C22H24N2O6, the indole ring has a twist conformation and the tetrahydro-2H-pyran-2-one ring a half-chair conformation. One of the pyrrolidine rings adopts an envelope conformation on the N atom, while the other has a twist conformation; the ‘butterfly’ angle between their mean planes is 62.98 (11)°. The dioxolane ring adopts a twist conformation and the tetrahydrofuran ring has an envelope conformation on the C atom in the fused tetrahydro-2H-pyran-2-one ring adjacent to the O atom of the tetrahydrofuran ring. The ‘butterfly’ angle between the mean planes of these two five-membered rings is 69.14 (10)°. In the crystal, molecules are linked by N—H⋯O hydrogen bonds, forming chains along the a axis.
