3-(2,4-Dimethoxyanilino)-8-methoxydibenz[b,e]oxepin-11(6H)-one
In the title compound, C23H21NO5, the two benzene rings of the tricyclic unit are oriented at a dihedral angle of 37.5 (8)°. The 2,4-dimethoxyanilino residue is oriented at a dihedral angle of 60.2 (8)° towards the phenoxy ring. In the crystal, the central carbonyl O atom accepts two hydrogen bonds from the N—H and C—H groups. A further intermolecular C—H...O interaction involving one of the methoxy O atoms is also observed.
3-(2,4-Difluoro-anilino)-9-nitro-dibenzo[b,e]oxepin-11(6H)-one.
In the title compound, C20H12F2N2O4, the two benzene rings of the tricyclic unit are oriented at a dihedral angle of 30.6 (1)°. The 2,4-difluoroanilino residue is oriented at a dihedral angle of 68.2 (1)° with respect to the phenoxy ring. In the crystal, N—H...O hydrogen bonds between the amino group and the carbonyl O atom of the oxepinone ring link the molecules into infinte chains along the c axis.
