In the title compound, C30H27ClN4O, the central pyrrolidine ring adopts an envelope conformation with the methyl-ene C atom being the flap. The quinoxaline and indane rings are each essentially planar, with r.m.s. deviations of 0.027 (1) and 0.0417 (1) Å, respectively. The pyrrolidine ring forms dihedral angles of 88.25 (1) and 83.76 (1)° with the quinoxaline and indane rings, respectively. A w...

The present work reports the study of the antimicrobial activity of four quinoxaline N,N-dioxide: quinoxaline 1,4-dioxide, 2-methylquinoxaline 1,4-dioxide, 6chloro-2,3-dimethylquinoxaline 1,4-dioxide and 3-benzoyl-2-methylquinoxaline 1,4dioxide against Geobacillus stearothermophilus ATCC 10149, Escherichia coli ATCC 25922, Escherichia coli HB101, Escherichia coli (blaTEM, blaCTX-M) and Salmonel...

The demonstration by Hurst and others (1953) of the effectiveness of quinoxaline-1: 4-dioxide and certain of its substituted derivatives against lymphogranuloma inguinale in mice and in developing chick embryos led to a request for the trial of one of the most active of these compounds in human lymphogranuloma. The selected compound was 2: 3 dimethyl quinoxaline-l : 4-dioxide (7218). This paper...

The effect of substituents in the aniline donor and type heterocyclic acceptor/donor moieties on yields 1,2-trans- 1,1-isomer ethylene D-π-A chromophores Pd-catalyzed Heck reaction has been studied. Various – derivatives quinoline, quinoxaline, benzothiazole, carbazole indolizine were synthesized.

In the title mol-ecule, C(14)H(9)N(3)O(3), the dihedral angle between the quinoxaline and benzene rings is 77.13 (9)°. The mol-ecule is twisted about the ether-benzene O-C bond, with a C-O-C-C torsion angle of -102.8 (2)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming layers in the ab plane, with one nitro O atom accepting two such inter-actions. The layers stack along ...

in this research, we have developed cheap recyclable and task-specific acidic ionic liquids (ails) 1-hydrogen-3-methylimidazolium hydrogen sulfate [hmim]hso4, 1-hydrogen-3-methylimidazolium chloride [hmim]cl, 2-pyrrolidonium hydrogensulfate [hnhp]hso4 and applied them in acid catalyzed synthesis of quinoxaline derivatives from 1,2-phenylendiamines and 1,2-dicarbonyl compounds. the products coul...

In the polymeric title copper(II) compound, [Cu(CHO(2))(2)(C(8)H(6)N(2))](n), both formato ligands are O-bidentate anions and act as bridging ligands, creating a planar polymeric arrangement. The slightly distorted square-pyramidal coordination around Cu(II) comprises four O atoms from two different formate anions as the base and a quinoxaline mol-ecule in the apical position.
