1′-Benzyl-4,4′′-bis­(4-chloro­phen­yl)-3-(2,6-dichloro­phen­yl)-1′′-methyl-4,5-dihydro­isoxazole-5-spiro-3′-piperidine-5′-spiro-3′′-pyrrolidine-2′′-spiro-3′′′-indoline-2′′′,4′-dione

The asymmetric unit of the title compound, C(43)H(34)Cl(4)N(4)O(3), contains two crystallographically independent mol­ecules. In both mol­ecules, the pyrrolidine ring adopts a twist conformation, the oxindole units are slightly distorted from planarity and the isoxazoline ring adopts an envelope conformation. The crystal structure is stabilized by N—H⋯O hydrogen-bonding inter­actions giving one-dimensional chain structures.
