In the title compound, C32H32N2O3S, the pyrrolidine ring adopts an envelope conformation with the methine C atom nearest to the phenyl ring as the flap atom. The tetra­hydro­pyridine ring has a half-chair conformation. The two rings are trans-fused. The phenyl ring bound to the tetra­hydro­pyridine is oriented almost perpendicular [dihedral angle = 86.35 (10)°] to the fused benzene ring. The dihedral angle between the benzyl­phenyl ring and the sulfonyl-bound phenyl ring is 69.43 (10)°. A very weak N—H⋯π inter­action is observed in the mol­ecular structure. In the crystal, mol­ecules translated one unit along the b axis are linked into C(10) chains by C—H⋯O hydrogen bonds; adjacent chains are linked via C—H⋯π inter­actions, forming a two-dimensional network parallel to the bc plane.

The asymmetric unit of the title compound, C26H30N2O4S, 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 a biaxial position and the sulfonyl group has distorted tetrahedral geometry. The A molecules are linked into a chain along the b axis by C—H...O hydrogen bonds, and the inversion‐related molecules of adjacent chains are cross‐linked into a two‐dimensional network parallel to the bc plane via C—H...π interactions involving the pyridinone ring, and π–π interactions involving the benzene ring of the quinolinone ring system. A similar two‐dimensional network is also formed by the B molecules. The centroid–centroid distances for the π–π interactions in the A and B molecules are 3.5477 (13) and 3.5743 (15) Å, respectively. The two‐dimensional networks formed by the A and B molecules are arranged alternately along the a axis, and are linked via C—H...π interactions involving the sulfonyl‐bound benzene ring of molecule B.
