Methyl (3S,3'R)-1-methyl-2,2''-dioxo-1',2',3',5',6',7',8',8a'-octa-hydro-dispiro-[indoline-3,2'-indolizine-3',3''-indoline]-1'-carboxyl-ate.

ABSTRACT: In the title compound, C(25)H(25)N(3)O(4), the central pyrrolidine ring and the two pyrrolidine rings adopt twisted conformations, whereas the piperidine ring in the octa-hydro-indolizine fused ring system adopts a chair conformation. The indoline ring systems are almost perpendicular with respect to the mean plane of the octa-hydro-indolizine ring system, making dihedral angles of 84.4?(5) and 79.4?(5)°. The acetate group attached to the octa-hydro-indolizine ring system assumes an extended conformation. In the crystal, N-H?O hydrogen bonds result in the formation of a helical C(7) chain running parallel to [101]. The crystal packing features C-H?O hydrogen bonds and C-H?? inter-actions.

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.

A second C-H⋯O inter-action arising from one of the C-H groups of the benzene ring links the dimers into [001] double chains.
