چکیده
The title compound, C(31)H(25)NO(6), has a structure related to other 3,4-diaryl-substituted maleic anhydride derivatives which have been shown to be useful as photochromic materials. The dihedral angles between the maleimide ring system and the benzene rings bonded to it are 44.48 (3) and 17.89 (3)°, while the angles between each of the latter rings and the corresponding ether bridging connected meth-oxy-benzene rings are 78.61 (8) and 72.67 (7)°. In the crystal, the molecules are linked by C-H⋯O inter-actions.

In the title compound, C(18)H(15)NO(4), the benzene rings form quite different dihedral angles [16.07 (1) and 59.50 (1)°] with the central pyrrole ring, indicating a twisted mol-ecule. Conjugation is indicated between the five- and six-membered rings by the lengths of the C-C bonds which link them [1.462 (3) and 1.477 (3) Å]. The most prominent feature of the crystal packing is the formation of...
متن کاملA general synthesis of bis-indolylpiperazine-2,5-diones.
The one-pot synthesis of three dragmacidin derivatives is reported. Sarcosine anhydride (4) is brominated and immediately reacted with the corresponding indole to produce the products, namely 3,6-bis(5'-methoxy-3'-indolyl)-1,4-dimethylpiperazine-2,5-dione (1), 3,6-bis(7'-methyl-3'-indolyl)-1,4-dimethylpiperazine-2,5-dione (2) and 3,6-bis-(6'-chloro-3'-indolyl)-1,4-dimethylpiperazine-2,5-dione (...
متن کاملFluorescence from bisaryl-substituted maleimide derivatives.
A series of bisaryl-substituted fluorescent maleimides was synthesized via the Heck arylation. The compounds showed broad fluorescence emission bands in the visible region, a large Stokes shift in polar solvents and emission quantum yields varying from 0.04 to 0.71, depending on the structure and solvent medium. The difference in dipole moments of ground and excited electronic states of about 1...
متن کاملStructural diversity in the first metal complexes of 2,5-dicarboxamidopyrroles and 2,5-dicarbothioamidopyrroles.
Metal complexes of 2,5-dicarboxamidopyrroles and 2,5-dicarbothioamidopyrroles have been structurally characterised for the first time, complementing the significant amount of work that has been reported for the analogous pyridine ligands. N,N'-Bis(3,5-dinitrophenyl)-3,4-diphenyl-1H-pyrrole-2,5-dicarboxamide forms octahedral bis(tridentate) complexes with cobalt(III) and nickel(II), where the li...
