Project description:In the title compound, C(27)H(24)N(2)O(3), the five-membered pyrroldine ring adopts an envelope conformation (with the N atom in the flap position) and the six-membered pyran-one ring of the coumarine ring system adopts a slightly distorted boat conformation. The oxindole unit makes dihedral angles of 89.7 (1) and 25.6 (1)°, respectively, with the pyrrolidine ring and the coumarin ring system. 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.

The 1'-methyl and 4'-phenyl groups on the pyrrolidine rings are substituted in equatorial positions. In the crystal, mol-ecules are linked into a three-dimensional network by N-H⋯O, N-H⋯N and C-H⋯O and N-H⋯π hydrogen bonds.

These are connected into layers in the ab plane via 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.

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.
