1′-Methyl-2-oxo-5′-phenylspiro[indoline-3,3′-pyrrolidine]-4′,4′-dicarbonitrile

The title spiro-compound, C20H16N4O, crystallizes with four independent molecules in the asymmetric unit. In all of them, the oxindole unit is planar, the r.m.s. deviations ranging from 0.07 to 0.08 Å, while the pyrrolinyl ring adopts an envelope conformation (with the N a...
