1'-Benzyl-4,4''-bis-(4-chloro-phen-yl)-3-(2,6-dichloro-phen-yl)-1''-methyl-4,5-dihydro-isoxazole-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 mol-ecules. In both mol-ecules, 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 inter-actions giving one-dimensional chain structures.
