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. |
