1-(4-{[8-(Trifluoromethyl)quinolin-4-yl]amino}phenyl)ethanone

Synthesis of new 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone moiety containing 4-thiazolidinone moiety

A series of novel 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone framework (4a-f) were synthesized through a four-step reaction starting from the reduction of nitro derivatives of 1, 8-dioxo-octahydroxanthenes. The resulting aminoxanthenes converted to thiourea derivatives via their reaction with methyl isothiocyanate. The final products were synthesized through the re...

[2,7-Dimethoxy-8-(4-methylbenzoyl)-1-naphthyl](4-methylphenyl)methanone

In the title compound, C(28)H(24)O(4), the two 4-methyl-benzoyl groups at the 1- and 8-positions of the naphthalene ring system are aligned almost anti-parallel, the dihedral angle between the two phenyl rings being 9.64 (7)°. The dihedral angles between the two phenyl rings and the naphthalene ring system are 71.82 (6) and 71.58 (6)°. In the crystal, inter-molecular C-H⋯O inter-actions between...

(4-Fluoro­phen­yl)[8-(4-fluoro­benzo­yl)-2,7-diphen­oxy­naphthalen-1-yl]methan­one

In the title compound, C(36)H(22)F(2)O(4), the aromatic rings of the benzoyl and phen-oxy groups make dihedral angles of 72.07 (5), 73.24 (5), 62.49 (5) and 77.96 (6)° with the naphthalene ring system. In the crystal, C-H⋯O hydrogen bonds and C-H⋯π inter-actions are observed.

(4-Eth­oxy­benzo­yl)[8-(4-eth­oxy­benzo­yl)-2,7-di­meth­oxy­naphthalen-1-yl]methanone

The title mol-ecule, C30H28O6, possesses crystallographically imposed twofold symmetry, with two central C atoms in the naphthalene unit lying on the rotation axis along [001]. The 4-eth-oxy-benzoyl groups at the peri positions of the naphthalene ring system are disordered over two sets of sites with occupancies of 0.769 (4) and 0.231 (4). They are directed in opposite directions from the napht...
