Spiro-[2-3′]oxindole-spiro-[3-3′′]oxindole-4[p-methylbenzyl]pyrrolidizine

The oxindole moieties of the title compound, C29H25N3O3, are planar. The pyrrolidine ring adopts a half-chair conformation. The structure is stabilized by C—H⋯O intramolecular interactions. It is remarkable that only one of the two NH groups forms a hydrogen bond.
