(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 کامل(2E)-2-[(2E)-3-Phenylprop-2-en-1-ylidene]-2,3-dihydro-1H-inden-1-one
The title indan-1-one derivative, C(18)H(14)O, is planar with an r.m.s. deviation for all 19 non-H atoms of 0.098 Å. The conformation about each of the C=C bonds [1.343 (3) and 1.349 (3) Å] is E. Supra-molecular layers in the bc plane, mediated by C-H⋯O and π-π [ring centroid-centroid distance = 3.5282 (15) Å] inter-actions, feature in the crystal packing.

In the title compound, C(16)H(15)NO(2), the isoindoline ring system is approximately planar (mean deviation = 0.0186 Å) and makes a dihedral angle of 61.91 (4)° with the phenyl ring. In the crystal, mol-ecules form inversion dimers via pairs of O-H⋯O hydrogen bonds.
متن کامل2,3-Dihydro-1H-pyrrolizin-1-one
There are two nearly identical mol-ecules in the asymmetric unit of the title compound, C(7)H(7)NO. The mol-ecules are nearly planar (r.m.s. deviations of 0.025 and 0.017 Å) and oriented at a dihedral angle of 28.98 (3)°. The two mol-ecules are linked by a C-H⋯O hydrogen bond. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into zigzag chains along the c axis.
متن کامل3-Methyl-1-propargylquinoxalin-2(1H)-one
The ten-membered fused ring of the title compound, C(12)H(10)N(2)O, is essentially planar in the two independent mol-ecules of the asymmetric unit (r.m.s. deviations = 0.012 and 0.015 Å).
