چکیده

The complete mol-ecule of the title compound, C(18)H(22)N(4)O(6), is generated by the application of a twofold axis of symmetry. Twists are evident in the mol-ecule, i.e. between each -C=N-N group and the adjacent oxazole ring [dihedral angle = 46.08 (12) °] and between the latter and attached ester group [excluding the terminal methyl group; dihedral angle = 24.4 (7) °]. In the crystal, C-H⋯O and π-π [3.5990 (11) Å] contacts connect mol-ecules into supra-molecular arrays in the ac plane. These stack along the b axis, being connected by weak π-π [3.3903 (11) Å] inter-actions.

In the title compound, C21H16BrNO3, the mean planes of the anthracene tricycle and isoxazole ring are inclined to each other at a dihedral angle of 72.12 (7)°. The carb-oxy group is slightly out of the isoxazole mean plane, with a maximum deviation of 0.070 (5) Å for the carbonyl O atom. In the crystal, pairs of weak C-H⋯O hydrogen bonds link the mol-ecules into dimers, and weak C-H⋯N inter-act...

In the title mol-ecule, C27H30N4O2S·C3H7NO, the fused piperidine and cyclo-hexane rings adopt a twin chair conformation and the phenyl groups occupy equatorial sites. The phenyl rings make a dihedral angle of 40.74 (2)°. In the crystal, the di-methyl-formamide solvent mol-ecule is connected to the main mol-ecule by an N-H⋯O hydrogen bond. An additional N-H⋯O hydrogen bond connects mol-ecules in...

In the title compound, C(30)H(31)NO(2), the cyclo-hexa-none ring in the naphthalene fused-ring system adopts a half-chair conformation, presumably due to conjugation of the benzene ring. The naphthalene ring system makes dihedral angles of 86.63 (7), 65.15 (8) and 63.18 (8)° with respect to the two methyl-benzene planes and the 1,2-oxazole ring system.
