1'-Methyl-4'-(1-naphth-yl)-3''-(1-naphthyl-methyl-ene)acenaphthene-1-spiro-2'-pyrrolidine-3'-spiro-1''-cyclo-hexane-2,2''-dione.

In the title compound, C42H33NO2, the six-membered cyclo­hexa­none ring adopts a slightly distorted chair conformation and the five-membered pyrrolidine ring is in an envelope conformation. The mol­ecular structure features four intra­molecular C—H⋯O inter­actions and an intra­molecular C—H⋯π inter­action. Furthermore, the crystal packing is stabilized by an inter­molecular C—H⋯O and three inter­molecular C—H⋯π inter­actions.
