In the zwitterionic title compound, C9H13NO2S, the pyrrolidine heterocycle adopts an envelope conformation (with the C atom in the 7-position as the flap). The negative charge is delocalized over the two carbonyl groups and the C atom connecting them. The positive charge is located on the S atom. Two intermolecular C—HO interactions are observed. The molecular geometry at the S atom is trigonal pyramidal.

In the title compound, C18H18N2O, the dihedral angle between the indole system and the phenyl ring is 17.2 (2)°. The crystal packing features two N—HO hydrogen bonds, which link the molecules into layers parallel to (001). The absolute configuration was determined by the synthetic procedure and was set according to the starting material.

In the title compound C17H25NO2, the piperidin-2-one ring adopts an envelope conformation with the C atom in the 5-position as the flap. The crystal packing is stabilized by intermolecular O—HO hydrogen bonds, building a infinite chain along the b-axis direction. C—Hπ interactions further stabilize the crystal packing.
