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

ABSTRACT: 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?? inter-actions.

Project description:Two spiro links are found in the title compound, C31H28Cl3N3O2, one connecting the piperidine and pyrrolidine rings, and the other connecting the pyrrolidine ring and indole residue. The piperidine ring adopts a half-chair conformation, in which the C atom connected to the spiro-C atom lies 0.741 (3) Å out of the plane of the remaining five atoms (r.m.s. deviation = 0.053 Å). The pyrrolidine ring has an envelope conformation with the flap atom being the methyl-ene C atom. Centrosymmetric eight-membered {⋯HNCO}2 amide dimers are the most significant feature of the crystal packing. These are connected into layers parallel to (-120) by C-H⋯O and π-π inter-actions between pyrrolidine-bound benzene rings [inter-centroid distance = 3.8348 (15) Å]. Slipped face-to-face inter-actions between the edges of pyrrolidine-bound benzene [shortest C⋯C separation = 3.484 (4) Å] connect the layers into a three-dimensional architecture.

5-Chloro-5''-(4-chloro-benzyl-idene)-4'-(4-chloro-phen-yl)-1',1''-dimethyldi-spiro-[indoline-3,2'-pyrrolidine-3',3''-piperidine]-2,4''-dione.

Project description:The racemic title compound, C30H26Cl3N3O2, comprises two spiro links, the first connecting the piperidine and pyrrolidine rings and the other connecting the indole and pyrrolidine rings. The piperidine ring adopts a half-chair conformation, while the pyrrolidine ring has an envelope conformation with the unsubstituted C atom as the flap. The dihedral angles between the two p-Cl-substituted benzene rings and the indole ring are 33.13 (14) and 54.11 (14)°. In the crystal, mol-ecules form inversion dimers through pairs of N-H⋯O hydrogen bonds [graph set R 2 (2)(8)]. Aromatic C-H⋯O hydrogen bonds extend these dimers into a ribbon structure, enclosing R (2) 2(14) ring motifs, along the a-axis direction.

Project description:The title compound, C34H38ClN5O2, has spiro links connecting the pyrrolidine ring and indole residue, as well as the piperidine and pyrrolidine rings. A half-chair conformation is found for the piperidine ring with the C atom connected to the spiro-C atom lying 0.738 (4) Å out of the plane of the remaining five atoms (r.m.s. deviation = 0.0407 Å). The methyl-ene C atom is the flap in the envelope conformation for the pyrrolidine ring. In the crystal, supra-molecular chains are sustained by alternating eight-membered {⋯HNCO}2 and 14-membered {⋯HC5O}2 synthons. Chains are connected into a three-dimensional network by (pyrrolidine-bound phenyl-meth-yl)C-H⋯π(pyrrolidine-bound phen-yl) edge-to-face inter-actions.

Three short C-H?O intra-molecular contacts occur. In the crystal, mol-ecules are linked by C-H?O and C-H?N inter-actions. The dichloro-methane solvent mol-ecule is disordered over two orientations in a 0.765?(11):0.235?(11) ratio.

5-(4-Fluoro-benzyl-idene)-4'-(4-fluoro-phen-yl)-1,1'-dimethyl-dispiro-[piperidine-3,3'-pyrrolidine-2',3''-indoline]-4,2''-dione.

Project description:The asymmetric unit of the title compound, C(30)H(27)F(2)N(3)O(2), contains two independent mol-ecules. The pyrrolidine five-membered ring assumes an envelope conformation (with the CH(2) atom at the flap) in one mol-ecule and a twisted conformation in the other one. In both independent mol-ecules, the 4-piperidinone rings adopt a similar twisted chair conformation. In the crystal, the two independent mol-ecules form an R(2) (2)(8) dimer through a pair of N-H⋯O hydrogen bonds; the R(2) (2)(8) dimers are connected via weak C-H⋯O hydrogen bonds, leading to a chain extending along the c axis.

Methyl 3'-benzyl-4'-(2,4-di-chloro-phen-yl)-1'-methyl-2-oxo-spiro-[indoline-3,2'-pyrrolidine]-3'-carboxyl-ate.

Project description:In the title compound, C27H24Cl2N2O3, the indole ring system is essentially planar, with a maximum deviation of 0.082 (2) Å for the carbonyl C atom. It makes a dihedral angle of 88.53 (6)° with the mean plane of the 4-methyl-pyrrolidine ring, which adopts an envelope conformation with the N atom at the flap position. The mol-ecular structure is stabilized by intra-molecular C-H⋯O hydrogen bonds, which generate S(6) and S(7) ring motifs, and an intra-molecular π-π inter-action involving the benzyl and di-chloro-substituted benzene rings [centroid-centroid distance = 3.6291 (11) Å]. In the crystal, mol-ecules are linked via N-H⋯O hydrogen bonds, forming C(7) chains running parallel to [10-1].
