{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.

6-Ferrocenoyl-7-phenyl-spiro-[hexa-hydro-pyrrolo-[1,2-c][1,3]thia-zole-5,11'-indeno-[1,2-b]quinoxaline].

Project description:In the title compound, [Fe(C5H5)(C32H24N3OS)], both the thia-zolidine ring and the pyrrolidine ring adopt an envelope conformation, with the S atom and the phenyl-bearing C atom, respectively, as the flaps. The thia-zolidine ring mean plane makes a dihedral angle of 59.08?(11)° with the pyrrolidine ring mean plane, which in turn makes a dihedral angle of 83.40?(10)° with the cyclo-pentane ring, indicating that the latter two rings are almost orthogonal to one another. In the crystal, a pair of C-H?O hydrogen bonds link the mol-ecules forming inversion dimers. The dimers are linked via ?-? inter-actions [centroid-centroid distance = 3.7764?(10)?Å] involving the quinoxaline moieties forming chains propagating along [1-10].

The pyrrolizine ring forms dihedral angles of 88.53 (5) and 89.95 (8)° with the quinoxaline-indene system and the indoline ring, respectively. The central pyrrolidine ring has an envelope conformation with the C atom bearing the quinoxaline-indene system as the flap.

The five-membered ring attached to the central pyrolidine ring adopts a twisted conformation. In the crystal, O-H⋯N and O-H⋯O hydrogen bonds between water mol-ecules and pyrrolizine N and carbonyl O atoms together with C-H⋯O inter-actions result in chains along [100].

2'-Methyl-2'-nitro-1'-phenyl-2',3',5',6',7',7a'-hexa-hydro-spiro-[indoline-3,3'-1'H-pyrrolizin]-2-one.

Project description:The title compound, C(21)H(21)N(3)O(3), was synthesized by a multi-component 1,3-dipolar cyclo-addition of azomethine ylide, derived from isatin and proline by a deca-rboxylative route, and (E)-1-phenyl-2-nitro-propene. In the mol-ecule, the spiro junction links a planar oxindole ring and a pyrrolidine ring in an envelope conformation. The mol-ecular packing is stabilized by an inter-molecular N-H?N inter-action of the oxindole and pyrrolizidine rings.
