1′,5-Dinitro-2′-phenyl-2′,3′,5′,6′,7′,7a’-hexahydrospiro[indoline-3,3′-1′H-pyrrolizin]-2-one
In the title cyclo-adduct, C(20)H(18)N(4)O(5), the rings of the pyrrolizine system adopt envelope conformations. A centrosymmetric dimer is formed via inter-molecular N-H⋯O hydrogen bonds between the indolinone rings.
متن کامل(E)-2-(2-Furylmethylidene)-2,3-dihydro-1H-pyrrolizin-1-one
The title compound, C(12)H(9)NO(2), was prepared by an Aldol reaction of furfuraldehyde with 2,3-dihydro-1H-pyrrolizin-1-one. The mol-ecule is almost planar, with an r.m.s. deviation of 0.045 Å, excluding the methyl-ene H atoms. In the crystal structure, mol-ecules are linked via weak inter-molecular C-H⋯O hydrogen bonding and aromatic π-π stacking [centroid-centroid distance = 3.6151 (9) Å].
متن کاملEthyl 2-[6-(4-methylbenzoyl)-7-phenyl-2,3-dihydro-1H-pyrrolizin-5-yl]-2-oxoacetate
In the title compound, C25H23NO4, the pyrrolizine ring is approximately planar with an r.m.s deviation from planarity of 0.0053 Å, while the fused di-hydro-pyrrolizine ring adopts an envelope conformation with the C atom connected to two CH2 as the flap. The dihedral angles between the fused ring system and the phenyl and methyl-benzoyl rings are 41.65 (11) and 66.30 (8)°, respectively. In the ...

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 add...
متن کامل2-Phenyl-1H-imidazole
In the title compound, C(9)H(8)N(2), a mirror plane lies perpendicular to the phenyl and imidazole rings and passes through the bridging C-C bond, so that the imidazole ring is disordered over two sites about the mirror plane with the equal site occupancy; the asymmetric unit contains one half-mol-ecule. In the crystal, adjacent mol-ecules are linked via N-H⋯N hydrogen bonds.
