4'-(4-Methoxy-phen-yl)-1,1',1''-trimethyl-dispiro-[indoline-3,2'-pyrrolidine-3',3''-pyrrolidine]-2,2'',5''-trione.

ABSTRACT: In the title compound, C(24)H(25)N(3)O(4), the pyrrolidine ring adopts an envelope conformation while the pyrrolidine-2'',5''-dione ring adopts a twist conformation. The indoline unit is planar [maximum deviation of -0.050?(9)?Å] and forms a dihedral angle of 40.36?(4)° with the methoxy-phenyl ring. Intra-molecular C-H?O hydrogen bonds are observed. In the crystal, mol-ecules are linked into a two-dimensional network parallel to the ab plane by inter-molecular C-H?O hydrogen bonds and C-H?? inter-actions.

Project description:In the title compound, C30H23N3O4, the central 1-methyl-pyrrolidine ring adopts a twist conformation on the N-CH2 bond. The pyrrolidin-2-one ring of the indolin-2-one ring system also has a twist conformation on the C-C bond involving the spiro C atom and the carbonyl C atom. The five-membered ring of the indene-1,3-dione moiety has an envelope conformation with the spiro C atom as the flap. The quinoline ring system adopts an almost planar conformation (r.m.s. deviation = 0.04 Å). The mean planes of the indolin-2-one ring system, the indene-1,3-dione ring system and the the quinoline ring system are inclined to the mean plane of the central 1-methyl-pyrrolidine ring by 77.97 (7), 86.98 (7) and 46.58 (6)°, respectively. In the crystal, mol-ecules are linked via N-H⋯N hydrogen bonds, forming chains along the b axis. The chains are linked via a number of C-H⋯O hydrogen bonds, and C-H⋯π and π-π inter-actions [inter-centroid distance = 3.7404 (9) Å], forming a three-dimensional network.

4'-(4-Fluoro-phen-yl)-1'-methyl-dispiro-[indane-2,2'-pyrrolidine-3',2''-indane]-1,3,1''-trione methanol hemisolvate.

Project description:The asymmetric unit of the title compound, C29H24FNO5·0.5CH3OH, contains two independent mol-ecules and a one methanol solvent mol-ecule. The methanol mol-ecule is O-H?O hydrogen bonded to one of the independent mol-ecules. The pyrrolidine rings in both mol-ecules adopt half-chair conformations, while the cyclo-pentane rings within the indane groups are in flattened envelope conformations, with the spiro C atoms forming the flaps. The benzene rings of the indane ring systems form a dihedral angle of 35.06?(7)° in one independent mol-ecule and 31.16?(8)° in the other. The fluoro-substituted benzene ring forms dihedral angles of 65.35?(6) and 85.87?(7)° with the indane group benzene rings in one mol-ecule, and 72.78?(8) and 77.27?(8)° in the other. In each mol-ecule, a weak intra-molecular C-H?O hydrogen bond forms an S(6) ring motif. In the crystal, weak C-H?O, C-H?N and C-H?F hydrogen bonds link the mol-ecules into a three-dimensional network.

Selective construction of dispiro[indoline-3,2'-quinoline-3',3''-indoline] and dispiro[indoline-3,2'-pyrrole-3',3''-indoline] via three-component reaction.

Project description:A convenient synthetic procedure for the construction of novel dispirooxindole motifs was successfully developed by base-promoted three-component reaction of ammonium acetate, isatins and in situ-generated 3-isatyl-1,4-dicarbonyl compounds. The piperidine-promoted three-component reaction of ammonium acetate, isatins and the in situ-generated dimedone adducts of 3-ethoxycarbonylmethyleneoxindoles afforded mutlifunctionalized dispiro[indoline-3,2'-quinoline-3',3''-indoline] derivatives in good yields and with high diastereoselectivity. On the other hand, a similar reaction of the dimedone adducts of 3-phenacylideneoxindoles afforded unique dispiro[indoline-3,2'-pyrrole-3',3''-indoline] derivatives with a cyclohexanedione substituent. A plausible reaction mechanism is proposed to explain the formation of the different spirooxindoles.

4'-(3-Bromo-phen-yl)-1'-methyl-dispiro-[indan-2,2'-pyrrolidine-3',2''-indan]-1,3,1''-trione.

Project description:In the title compound, C(27)H(20)BrNO(3), two intra-molecular C-H?O hydrogen bonds both form S(6) rings. The pyrrolidine ring adopts a twisted conformation about the C-C bond bearing the indane ring systems.

The mean plane of the pyrrolidine ring [maximum deviation = 0.275?(1)?Å] makes dihedral angles of 65.25?(7), 78.33?(6) and 75.25?(6)° with the bromo-substituted benzene ring and the mean planes of the mono- and dioxo-substituted indane rings, respectively. In the crystal, mol-ecules are linked by C-H?O and C-H?N hydrogen bonds into a three-dimensional network. In addition, C-H?? inter-actions are observed.

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.
