{1'-Phenyl-1',2',5',6',7',7a'-hexa-hydro-spiro-[indeno-[1,2-b]quinoxaline-11,3'-pyrrolizin]-2'-yl}(p-tol-yl)methanone.

ABSTRACT: In the title compound, C(35)H(29)N(3)O, the quinoxaline and indene systems are essentially planar, with maximum deviations of 0.047 (2) and 0.032 (2) Å for C atoms, respectively. The quinoxaline system forms a dihedral angle of 4.75 (3)° with the indene system. The pyrrolizine system is folded. The substituted five-membered ring adopts an envelope conformation. In the other five-membered ring, one C atom is disordered with a site-occupancy ratio of 0.676 (12):0.324 (12). In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds involving the bifurcated carbonyl O atom.
