The title compound, C23H20N2O6, crystallizes with two molecules in the asymmetric unit in which the dihedral angles between the mean planes of the pyran and phenyl rings are 66.6 (1) and 61.9 (1) °. The fused pyrone and pyran rings each adopts a sofa conformation. In the crystal, C—H
O hydrogen bonds link the molecules, forming a two-dimensional network parallel to [001].

In the title compound, C27H25ClN2O3, the methylpyrrolidine ring adopts an envelope conformation with the N atom at the flap. The mean plane of the pyrrolidine ring makes dihedral angles of 82.1 (1), 84.4 (1) and 79.8 (1)°, respectively, with the adjacent benzene ring, the mean plane of the indoline ring system and the phenyl ring. The molecular structure is stabilized by intramolecular C—HO hydrogen bonds. In the crystal, molecules are linked into chains along [101] by N—HO hydrogen bonds. C—Hπ interactions are observed between the chains.

In the title compound, C20H19NO2, the dihedral angle between the benzene rings is 77.12 (8)°. The terminal isopropyl group is disordered over two orientations, with site occupancies of 0.720 (14) and 0.280 (14). In the crystal, molecules are linked through a weak C—HO interaction, forming a zigzag chain along the c-axis direction.
