3-(4-Fluoro-phenyl)-1-[1'-(4-fluoro-phenyl)-2-oxo-5',6',7',7a'-tetra-hydro-1H-indole-3(2H)-spiro-3'(2'H)-1H'-pyrrol-izin-2'-yl]prop-2-en-1-one.

ABSTRACT: In the title compound, C(29)H(24)F(2)N(2)O(2), one of the pyrrolidine rings of the pyrrolizine system is disordered over two sites, with occupancy factors 0.734:0.266?(12). Both components of the disordered pyrrolidine ring adopt envelope conformations, whereas the other pyrrolidine ring adopts a twist conformation. The mol-ecules are linked into centrosymmetric dimers by N-H?O hydrogen bonds and the dimers are connected via C-H?? inter-actions. The crystal structure is also stabilized by inter-molecular C-H?F hydrogen bonds.

5-Fluoro-N-(2-methyl-3-oxo-1-thia-4-aza-spiro-[4.5]dec-4-yl)-3-phenyl-1H-indole-2-carboxamide.

Project description:In the title compound, C24H24FN3O2S, the 1,3-thia-zolidine ring adopts an envelope conformation with the S atom as the flap, while the cyclo-hexane ring is in a chair conformation. In the crystal, mol-ecules are linked by N-H?O and C-H?F hydrogen bonds, forming a three-dimensional network. The unit cell contains six voids of 57?Å(3), but the residual electron density (highest peak = 0.23?e?Å(-3) and deepest hole = -0.19?e?Å(-3)) in the difference Fourier map suggests no solvent mol-ecule occupies this void.

Project description:In the title pyrrolizidine derivative, C33H26F2N2O2, both pyrrolidine rings of the pyrrolizidine moiety adopt an envelope conformation. The di-fluoro-phenyl group is oriented at an angle of 54.3?(1)° with respect to the oxindole moiety. The crystal packing features an N-H?O hydrogen bond, which forms an R 2 (2)(8) motif, and a C-H?O inter-action, which generates a C(8) chain along [010]. In addition, this chain structure is stabilized by C-H?? inter-actions. In one of the pyrrolidine rings, the methyl-ene group forming the flap of an envelope and the H atoms of the adjacent methyl-ene groups are disordered over two sets of sites, with site-occupancy factors of 0.571?(4) and 0.429?(4).
