(E)-3-(Oxolan-2-ylidene)-1-phenylpyrrolidine-2,5-dione
In the title compound, C14H13NO3, the dihedral angles between the central pyrrolidine ring and the pendant tetra-hydro-furan and phenyl rings are 5.34 (18) and 58.99 (17)°, respectively. The tetra-hydro-furan ring is almost planar (r.m.s. deviation = 0.008 Å). In the crystal, mol-ecules are linked by C-H⋯O inter-actions, generating a three-dimensional network.

The title compound, C(14)H(14)BrNO(5), has two chiral C atoms. The quaternary C atom in the oxolanone ring has an S configuration, while the adjacent tertiary C atom has an R configuration. The oxolanone ring adopts an envelope conformation, with the flap C atom lying 0.298 (3) Å from the mean plane of the remaining four atoms. In the crystal, mol-ecules are connected into chains along [010] vi...

The title compound, C(14)H(11)N(3)O(3), adopts an E or trans configuration with respect to the C=N bond. In the mol-ecule there is an intra-molecular O-H⋯N hydrogen bond involving the hy-droxy substituent at the 2-positon of the naphthalene ring and the adjacent methyl-ene-amino N atom. The mol-ecule is roughly planar, the dihedral angle between the naphthalene and imidazolidine-2,4-dione mean ...

The title compound, C(19)H(12)N(2)O(3), has two independent mol-ecules (A and B) in the asymmetric unit. There is an intra-molecular O-H⋯N hydrogen bond in each mol-ecule. The mean planes of the naphthalene [maximum deviations = 0.024 (3) and 0.030 (3) Å in A and B, respectively] and the isoindoline units [maximum deviations 0.009 (3) and 0.008 (3) Å in A and B, respectively] are almostly copla...

The title compound, C(16)H(11)N(3)O(2), displays a trans configuration with respect to the azo group. The mol-ecule is non-planar; the maleimide ring forms a dihedral angle of 42.35 (4)° with the benzene ring bonded to its N atom and the mean plane of this benzene ring is rotated by 21.46 (8)° with respect to the azo group mean plane, which, in turn, forms a dihedral angle of 24.48 (7)° with th...
