1′,6-Dimethyl-4′-phenyl­dispiro­[1-benzopyran-3(4H),3′-pyrrolidine-2′,3′′-indoline]-2,2′′-dione

In the title compound, C(27)H(24)N(2)O(3), the five-membered pyrroldine ring adopts an envelope conformation (with the N atom in the flap position) and the six-membered pyran­one ring of the coumarine ring system adopts a slightly distorted boat conformation. The oxindole unit makes dihedral angles...

Sumario:In the title compound, C(27)H(24)N(2)O(3), the five-membered pyrroldine ring adopts an envelope conformation (with the N atom in the flap position) and the six-membered pyran­one ring of the coumarine ring system adopts a slightly distorted boat conformation. The oxindole unit makes dihedral angles of 89.7 (1) and 25.6 (1)°, respectively, with the pyrrolidine ring and the coumarin ring system. The mol­ecular structure is stabilized by two intra­molecular C—H⋯O contacts and two intra­molecular π–π inter­actions [centroid–centroid seperations of 3.514 (1) and 3.623 (1) Å]. The crystal packing features N—H⋯O hydrogen bonds, which link the mol­ecules into cyclic centrosymmetric R (2) (2)(8) dimers, and C—H⋯π inter­actions.
