(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].

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.

The title compound, C(9)H(11)NO(3), was prepared by an Aldol reaction of 2,3-dihydro-1H-pyrrolizin-1-one with formaldehyde. The asymmetric unit contains six mol-ecules. The pyrrolizine ring system in each mol-ecule is planar, the maximum atomic deviation being 0.066 (2) Å. In the crystal structure, mol-ecules are liked together by an extensive O-H⋯O hydrogen-bonding network.

In the title compound, C(21)H(21)NO, the indene ring system is essentially planar with a maximum deviation of 0.066 (1) Å and makes dihedral angles of 7.93 (6) and 2.43 (6)°, respectively, with the benzene plane and the mean plane of the piperidine ring. These latter two planes make a dihedral angle of 7.61 (7)°. In the crystal, mol-ecules are linked by C-H⋯O inter-actions, forming infinite cha...

The mol-ecule of the title compound, C(23)H(17)NO(2), a Schiff base derived from 2-hydr-oxy-1-naphthaldehyde, crystallizes in the keto-amine tautomeric form. The dihedral angle between the aniline and hydroxy-benzene rings is 77.41 (17)°, whereas the planes of the naphthaldehyde and fused aniline benzene rings are nearly coplanar, making a dihedral angle of 8.29 (15)°. Intra-molecular N-H⋯O hyd...
