4-Hydr­oxy-3-(1′-methyl-2-oxo-4′-phenyl­spiro­[indoline-3,2′-pyrrolidine]-3′-yl­carbon­yl)quinolin-2(1H)-one

摘要

In the title compound, C28H23N3O4, the dihedral angle between the quinoline and indole ring systems is 29.30 (5)°. The pyrrolidine ring adopts a twist conformation. An intra­molecular O—H⋯O hydrogen bond generates an S(6) ring motif. A weak intra­molecular C3—H3⋯O3 inter­action is also observed. In the crystal, mol­ecules are linked by two sets of N—H⋯O hydrogen bonds, forming centrosymmetric dimers containing two R 2 2(8) ring motifs. The dimers are linked via C—H⋯π inter­actions.
