1',1''-Dimethyl-4'-phenyl-dispiro-[11H-indeno-[1,2-b]quinoxaline-11,2'-pyrrolidine-3',3''-piperidin]-4''-one.

ABSTRACT: In the title compound, C30H28N4O, the central pyrrolidine ring adopts an envelope conformation with the CH2 C atom as the flap. The quinoxaline and indene ring systems are planar, with r.m.s. deviations of 0.0165 and 0.0181?Å, respectively. The pyrrolidine ring mean plane forms dihedral angles of 88.84?(1) and 86.14?(1)° with the quinoxaline and indene ring systems, respectively. A weak intra-molecular C-H?N inter-action is observed. In the crystal, C-H?O inter-actions lead to helical supra-molecular chains along the b axis having a C(9) motif.

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].

Project description:In the title compound, C36H30N4O3, the quinoxaline-indene system is roughly planar, with a maximum deviation from the mean plane of 0.218 Å for the C atom shared with the central pyrrolidine ring.

The central pyrrolidine ring has an envelope conformation with the N atom as the flap, while the pyrrolidine and five-membered rings of the indole group adopt twisted conformation and envelope (with the C atom bearing the quinoxaline-indene system as the flap) conformations, respectively. In the crystal, mol-ecules are linked via weak C-H⋯N hydrogen bonds, forming a chain running along [100].

The mol-ecular structure is stabilized by two intra-molecular C-H⋯O contacts and two intra-molecular π-π inter-actions [centroid-centroid seperations of 3.514 (1) and 3.623 (1) Å]. The crystal packing features N-H⋯O hydrogen bonds, which link the mol-ecules into cyclic centrosymmetric R(2) (2)(8) dimers, and C-H⋯π inter-actions.

5''-Benzyl-idene-5-chloro-1',1''-dimethyl-4'-phenyl-dispiro-[indoline-3,2'-pyrrolidine-3',3''-piperidine]-2,4''-dione.

Project description:The title compound, C30H28ClN3O2, features two spiro links, one connecting the piperidine and pyrrolidine rings, and the other connecting the pyrrolidine ring and indole residue. The configuration about the ethene bond is E. The piperidine ring adopts a half-chair conformation where the C atom connected to the spiro-C atom lies 0.713 (3) Å out of the plane of the remaining five atoms (r.m.s. deviation = 0.086 Å). The pyrrolidine ring has an envelope conformation with the flap atom being the methyl-ene C atom. Centrosymmetric eight-membered {⋯HNCO}2 amide synthons feature in the crystal packing. These are consolidated into a three-dimensional architecture by phen-yl-pyrrolidine C-H⋯N and chloro-benzene-pyrrolidine-bound phenyl C-H⋯π inter-actions.
