✦ Synopsis

The molecule of the title compound, C~26~H~30~N~2~O~4~S, adopts a folded conformation, with the sulfonyl-bound benzene ring lying over the pyridinone ring [centroid-to-centroid distance = 3.893β€…(1)β€…Γ…], forming a dihedral angle of 23.87β€…(5)Β°. The pyrrolidine ring adopts a twist conformation and the dihydropyran ring is in a half-chair conformation. The pyrrolidine and dihydropyran rings are cis-fused. The sulfonyl group has a distorted tetrahedral geometry. In the crystal structure, the molecules are linked into a centrosymmetric R
~2~
^2^(12) dimer by Cβ€”H...O hydrogen bonds. The dimers are cross-linked into a sheet parallel to the bc plane via Cβ€”H...Ο€ interactions involving the benzene ring of the quinolinone ring system. The ethyl group is disordered over two positions; the site-occupancy factors are ca 0.8 and 0.2.

The asymmetric unit of the title compound, C 26 H 30 N 2 O 4 S, consists of two independent molecules, A and B, with similar conformations. In both molecules, the pyrrolidine and dihydropyran rings adopt envelope conformations, and are trans-fused; the tosyl group is attached to the pyrrolidine ring

In the title compound, C~26~H~24~N~2~S, the six- and seven-membered heterocyclic rings adopt half-chair and near-boat conformations, respectively. The molecular conformation is influenced by two weak intramolecular Cβ€”H...N interactions. The crystal structure is stablized by intermolecular Cβ€”H...N an
