Methyl 4-(4-bromo-anilino)-2',5-dioxo-5H-spiro-[furan-2,3'-indoline]-3-carboxyl-ate.

ABSTRACT: In the title compound, C19H13BrN2O5, the spiro furan ring is almost planar with a maximum deviation of 0.034?(2)?Å. The indole unit and the furan ring are normal to each other, making a dihedral angle of 87.82?(8) °. The mol-ecular structure is stabilized by an intra-molecular N-H?O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules are linked via pairs of N-H?O hydrogen bonds, forming inversion dimers enclosing R (2) 2(8) ring motifs.

Methyl 4-anilino-2',5-dioxo-1',2'-di-hydro-5H-spiro-[furan-2,3'-indole]-3-carboxyl-ate.

Project description:In the title compound, C19H14N2O5, the spiro junction links an oxindole moeity and a furan ring, which subtend a dihedral angle of 83.49?(6)°. The mol-ecular structure features an N-H?O hydrogen bond, which generates an S(6) ring motif. The crystal packing is governed by two N-H?O inter-actions, one of which generates a centrosymmetric R 2 (2)(14) dimer. The other N-H?O inter-action along with a C-H?O hydrogen bond contributes to the formation of a C 2 (2)[R 2 (2)(9)] dimeric chain running along the b-axis direction.
