Crystal structure of 3′-(1H-indole-3-carbonyl)-1′-methyl-2-oxo-4′-(4-oxo-4H-chromen-3-yl)spiro[indoline-3,2′-pyrrolidine]-3′-carbonitrile

Crystal structure of 3′-(1H-indole-3-carbonyl)-1′-methyl-2-oxo-4′-(4-oxo-4H-chromen-3-yl)spiro[indoline-3,2′-pyrrolidine]-3′-carbonitrile

In the title compound, C31H22N4O4, the pyrrolidine ring adopts a twist conformation on the N—CH2 bond. The indolin-2-one and the 1H-indole rings are nearly planar (r.m.s. deviations = 0.06 and 0.011 Å, respectively) and are inclined to one another by 34.19 (9)°. The chromene ring system is also near...
