Abstract

The title molecule, C₂₂H₂₃N₃O₂, was obtained via an intramolecular cycloaddition of an azomethine ylide and an alkene tethered by a benzimidazole unit. The benzoimidazole unit is essentially planar, with an r.m.s. deviation of 0.0087 Å from the nine constituent atoms. It has a cis fusion of the two pyrrolidine rings as well as a cis ester appendage. The two pyrrolidine rings rings have envelope conformations. The crystal packing is stabilized by aromatic π-π stacking of parallel benzimidazole ring systems, with a centroid-tocentroid distance of 3.518 (6) Å. Weak intermolecular C-H⋯O contacts may also play a role in the stability of the packing.
