  ABSTRACT: In the title compound, C21H16O4, the dihedral angle between the phenyl ring and the 2H-chromene ring system is 59.8 (2)°. The crystal packing is stabilized by weak π–π stacking interactions [centroid–centroid distances = 3.667 (2) Å] and intermolecular C—H...O hydrogen-bonding interactions.

  ABSTRACT: In the title compound, C32H31NO4, the dihedral angles between the indoline ring and the two phenyl rings are 48.11 (9) and 66.55 (9)°. The molecular conformation is stabilized by a weak intramolecular π–π stacking interaction [centroid–centroid distance = 3.6377 (7) Å]. The crystal structure is stabilized by intermolecular C—H...O hydrogen bonds, which form chains along the b axis.
