In the title compound, C36H29Cl2NO4, two spiro links connect the methyl-substituted pyrrolidine ring to the acenaphthylene and cyclohexanone rings. The cyclohexanone ring is further connected to the dioxalane ring by a third spiro junction. The five-membered ring of the acenaphthylen-1-one ring system adopts a flattened envelope conformation, with the ketonic C atom as the flap, whereas the dioxalane and pyrrolidine rings each have a twist conformation. The cyclohexenone ring assumes a boat conformation. An intramolecular C—H...O hydrogen-bond interaction is present. In the crystal, molecules are linked by non-classical C—H...O hydrogen bonds, forming chains extending parallel to theaaxis.

In the title compound the four-fused-rings system is approximately planar and the pyrrolidine rings of the pyrrolidizine fragment adopt a twist conformation. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds and C—H⋯π inter­actions, forming double-chains parallel to the c axis.

In the title tris­piro compound, both the methyl-substituted pyrrolidine and dioxalane rings adopt a twist conformation. The cyclo­penta­none ring of the acenapthylen-1-one system adopts flattened envelope conformation, and the cyclo­hexa­none attached to the dioxalane ring adopts boat conformation. In the crystal, centrosymmetrically related mol­ecules are linked into dimers forming rings of (10) graph-set motif, which are further connected into chains parallel to the b axis by C—H⋯O contacts forming rings of (8) graph-set motif.
