title: Crystal structure of 15-(naphthalen-1-yl)-7,7a,8,9,10,11-hexa-hydro-6a,12a-(methano-epoxy-methano)-indolizino[2,3-c]quinoline-6,13(5H)-dione.
abstract: In the title compound, C27H24N2O3, the dihedral angle between the mean planes of the di-hydro-furan and 3,4-di-hydro-quinoline ring systems is 70.65 (9)°. The di-hydro-furan ring adopts an envelope conformation with the C atom adjacent to the methyl-ene C atom of the pyrrolidine ring as the flap. The five-membered pyrrolidine ring adopts a twist conformation on the N-C(tetra-substituted) bond. In the crystal, mol-ecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(8) ring motif. The dimers are linked via pairs of C-H⋯O hydrogen bonds, forming ribbons enclosing R 2 (2)(12) ring motifs lying in a plane parallel to (01-1).
