1,1''-Bis(prop-2-en-1-yl)-1,1'',2,2''-tetra-hydro-dispiro-[indole-3,7'-[6,9]diaza-tricyclo-[7.3.0.0(2,6)]dodecane-8',3''-indole]-2,2''-dione.
The mol-ecule of the title compound, C(30)H(32)N(4)O(2), lies on a twofold rotation axis that passes through the mid-points of the C-C bonds of the piperazine ring, which adopts a chair conformation. The pyrrolidine ring that is fused to the piperazine ring adopts an envelope conformation (in which the N atom represents the flap). The indoline fused-ring system is nearly planar (r.m.s. deviation = 0.044 Å); the two symmetry-related indoline fused-rings systems are aligned at 71.44 (3)°.
