1',1''-Dimethyl-4'-(naphthalen-1-yl)-1,2,3,4-tetra-hydro-naphthalene-2-spiro-3'-pyrrolidine-2'-spiro-3''-indoline-1,2''-dione.

ABSTRACT: In the title compound, C(32)H(28)N(2)O(2), the pyrrolidine ring adopts an envelope conformation, whereas the cyclo-hexa-none ring in the tetra-hydro-naphthalene fused-ring system adopts a half-chair conformation. The oxindole ring system is oriented at an angle of 48.2 (1)° with respect to the naphthyl ring system. An intra-molecular C-H⋯O close contact is observed. In the crystal, mol-ecules associate via two C-H⋯O hydrogen bonds, forming R(2) (2)(14) and R(2) (2)(10) dimers.

Project description:In the title compound, C(33)H(28)N(2)O(4), the central pyrrolidine ring adopts a half-chair conformation. Both the indolinone and indanone groups are twisted, with their five-membered rings adopting a half-chair and an envelope conformation, respectively.
