Crystal structure of 5''-(4-chloro-benzyl-idene)-4'-(4-chloro-phen-yl)-1'-methyltri-spiro[acenapthylene-1,2'-pyrrolidine-3',1''-cyclo-hexane-3'',2'''-[1,3]dioxane]-2(1H),6''-dione.

ABSTRACT: In the title compound, C36H29Cl2NO4, two spiro links connect the methyl-substituted pyrrolidine ring to the ace-naphthyl-ene and cyclo-hexa-none rings. The cyclo-hexa-none ring is further connected to the dioxalane ring by a third spiro junction. The five-membered ring of the ace-naphthylen-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 cyclo-hexenone ring assumes a boat conformation. An intra-molecular C-H?O hydrogen-bond inter-action is present. In the crystal, mol-ecules are linked by non-classical C-H?O hydrogen bonds, forming chains extending parallel to the a axis.
