Crystal structure of 4′-(2-methoxyquinolin-3-yl)-1′-methyldispiro[indan-2,2′-pyrrolidine-3′,3′′-indoline]-1,3,2′′-trione
In the title compound, C30H23N3O4, the central 1-methyl-pyrrolidine ring adopts a twist conformation on the N-CH2 bond. The pyrrolidin-2-one ring of the indolin-2-one ring system also has a twist conformation on the C-C bond involving the spiro C atom and the carbonyl C atom. The five-membered ring of the indene-1,3-dione moiety has an envelope conformation with the spiro C atom as the flap. Th...
