Crystal structure of 15-(naphthalen-1-yl)-7,7a,8,9,10,11-hexahydro-6a,12a-(methanoepoxymethano)indolizino[2,3-c]quinoline-6,13(5H)-dione

Abstract

In the title compound, C27H24N2O3, the dihedral angle between the mean planes of the dihydrofuran and 3,4-dihydroquinoline ring systems is 70.65 (9)°. The dihydrofuran ring adopts an envelope conformation with the C atom adjacent to the methylene C atom of the pyrrolidine ring as the flap. The five-membered pyrrolidine ring adopts a twist conformation on the N—C(tetrasubstituted) bond. In the crystal, molecules are linked via pairs of N—H...O hydrogen bonds, forming inversion dimers with an R22(8) ring motif. The dimers are linked via pairs of C—H...O hydrogen bonds, forming ribbons enclosing R22(12) ring motifs lying in a plane parallel to (01-1).
