5-Methyl-spiro-[indoline-3,7'-[6H,7H,8H]pyrano[3,2-c:5,6-c']di[1]benzopyran]-2,6',8'-trione chloroform hemisolvate.

Project description:In the title compound, C(27)H(15)NO(6)·0.5CHCl(3), the central pyran ring and both the benzopyran systems are planar, with the dihedral angle between the outer rings being 3.24?(6)°. The indolin-2-one system is in a perpendicular configuration with respect to the pyran ring [dihedral angle = 87.58?(2)°]. Supra-molecular layers in the ac plane are formed in the crystal structure whereby inversion-related mol-ecules are connected by N-H?O hydrogen bonds. These are further linked by C-H?O inter-actions, forming a supra-molecular layer in the ac plane. Disordered CHCl(3) solvent in the structure was modelled with the SQUEEZE routine in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155].

5'-Amino-2-oxo-2',3'-dihydro-spiro-[indoline-3,7'-thieno[3,2-b]pyran]-6'-carbonitrile 1',1'-dioxide.

Project description:In the title compound, C(15)H(11)N(3)O(4)S, the dihedral angle between the mean planes of the dihydro-indol-2-one (r.m.s. deviation = 0.015?Å) and dihydro-thieno[3,2-b]pyran (r.m.s. deviation = 0.011?Å) ring systems is 89.53?(3)°. The crytal packing is consolidated by inter-molecular N-H?O and N-H?N hydrogen bonds, which link the mol-ecules into a two-dimensional network into sheets lying parallel to (100).

5,6-Dimethyl-1,2,9,10-tetra-hydro-pyrano[3,2-f]chromene-3,8-dione.

Project description:The title mol-ecule, C(14)H(14)O(4), lies on a twofold rotation axis that bis-ects the central benzene ring, with only one half-mol-ecule in the asymmetric unit. The pyran-one systems adopt distorted twist- boat conformations, with the two methyl-ene C atoms displaced by 0.537?(1) and 0.163?(2)?Å from the best-fit plane through the remaining five C and O atoms (r.m.s. deviation = 0.073?Å). In the crystal, bifurcated C-H?(O,O) hydrogen bonds link pairs of adjacent mol-ecules in an obverse fashion, stacking mol-ecules along c. These contacts are further stabilized by very weak ?-? inter-actions between adjacent benzene rings with centroid-centroid distances of 4.1951?(4)?Å. Additional C-H?O contacts link these stacks, giving a three-dimensional network.

5,6-Dichloro-2-(2-fluoro-phen-yl)iso-indoline-1,3-dione.

Project description:The crystal structure of the title compound, C(14)H(6)Cl(2)FNO(2), exhibits C-H?? and ?-? inter-actions, which generate C(3) chains in the [100] direction. The ?-? inter-action occurs between the aromatic rings of isoindoline units, with a centroid-centroid distance of 3.672?Å and an inter-planar separation of 3.528?Å. The isoindoline unit is planar and inclined at an angle of 58.63?(18)° to the substituent benzene ring. The F atom is disordered over two positions, with refined occupancies of 0.669?(3) and 0.331?(3).

5,6-Dimeth-oxy-4',5'-diphenyl-indane-2-spiro-3'-pyrrolidine-2'-spiro-3''-indoline-1,2''-dione.

Project description:In the title compound, C(33)H(28)N(2)O(4), the central pyrrolidine ring adopts a half-chair conformation. Both the indolinone and indanone groups are twisted, with their five-membered rings adopting a half-chair and an envelope conformation, respectively. The two benzene rings and the mean plane of the indolinone and indanone groups make dihedral angles of 71.98?(10), 84.32?(10), 86.26?(9) and 78.50?(9)°, respectively, with the central pyrrolidine ring. Intra-molecular C-H?O hydrogen bonds stabilize the mol-ecular conformation. In the crystal, pairs of inter-molecular N-H?O hydrogen bonds link the mol-ecules into centrosymmetric dimers. The dimers are inter-connected into ribbons propagating along [110] via weak inter-molecular C-H?O hydrogen bonds. Weak inter-molecular C-H?? and ?-? [centroid-centroid distance = 3.6509?(11)?Å] inter-actions are also observed.

Methyl 5''-chloro-1',1''-dimethyl-2,2''-dioxodi-spiro-[indoline-3,2'-pyrrolidine-3',3''-indoline]-4'-carboxyl-ate.

Project description:In the title compound, C22H20ClN3O4, the central pyrrolidine ring adopts an envelope conformation on the N atom. The indolinone systems are individually roughly planar, with maximum deviations from their mean planes of 0.130 Å for the spiro C atom of the indolinone unit and 0.172 Å for the carbonyl C atom of the 5-chloro-1-methyl-indolinone unit. They make dihedral angles of 77.7 (8) and 86.1 (8)° with the mean plane through the central pyrrolidine ring. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds supported by C-H⋯O contacts into chains along the ab diagonal. The structure also features C-H⋯O hydrogen bonds, forming R 2 (2)(8) and R 2 (2)(16) rings and generating a three-dimensional array.

Facile synthesis of functionalized spiro[indoline-3,2'-oxiran]-2-ones by Darzens reaction.

Project description:A series of functionalized spiro[indoline-3,2'-oxiran]-2-ones was efficiently synthesized by Darzens reaction of phenacyl bromides with isatins both with N-alkyl groups and without N-substituent in the presence of potassium carbonate as a base catalyst. When two equivalents phenacyl bromides were used in the reaction, the N-substitution reaction of isatin also finished with the formation of spiro-oxirane-oxindoles.
