title: tert-Butyl 3-benzyl-3-[(E)-2-benzyl-idene-3-oxocyclo-pent-yl]-2-oxoindoline-1-carboxyl-ate.
abstract: In the title compound, C(32)H(31)NO(4), the dihedral angles between the indoline ring and the two phenyl rings are 48.11 (9) and 66.55 (9)°. The mol-ecular conformation is stabilized by a weak intramolecular π-π stacking inter-action [centroid-centroid distance = 3.6377 (7) Å]. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds, which form chains along the b axis.
