17O NMR studies of electronic and steric interactions of substituted quinoxaline-2(1H),3(4H)-diones

17O nmr studies, at natural abundance, of substituted quinoxaline-2(1H),3(4H)-diones demonstrate that the 17O chemical shift data can provide new insights into steric and electronic interactions due to long range substituent effects on the aromatic ring. The role of considerable “keto” character and torsion angle deformation of the diamide group in solution is emphasized.

Potent quinoxaline-based inhibitors of PDGF receptor tyrosine kinase activity. Part 1: SAR exploration and effective bioisosteric replacement of a phenyl substituent

Novel substituted 2-anilino- and 2-cycloalkylaminoquinoxalines have been found to be useful and selective inhibitors of PDGF-R autophosphorylation. Replacement of an anilino-substituent with substituted cyclohexylamino- or norbornylamino substituents led to significant improvements in the pharmacokinetic profile of these analogues.

Construction of C(sp2)?C(sp3) Bond between Quinoxalin-2(1H)-ones and N-Hydroxyphthalimide Esters via Photocatalytic Decarboxylative Coupling

A novel visible-light-driven decarboxylative coupling of alkyl N-hydroxyphthalimide esters (NHP esters) with quinoxalin-2(1H)-ones has been developed. This C(sp2)?C(sp3) bond-forming transformation exhibits excellent substrate generality with respect to both the coupling partners. Of note, a series of 3-primary alkyl-substituted quinoxalin-2(1H)-ones that were difficult to synthesize by previous methods could be obtained in moderate to excellent yields. Additionally, the mild conditions, easy availability of substrates, wide functional group tolerance and operational simplicity make this protocol practical in the synthesis of 3-alkylated quinoxalin-2(1H)-ones.

New donor-functionalized Cp ligands: Synthesis and complexation behaviour of quinoxalyl and benzothiadiazolyl systems

Sodium cyclopentadienide reacts as nucleophile with 4,7-dibromo-2,1,3- benzothiadiazole (BTZ) and leads to the new donorfunctionalized ligand Cp BTZ. Related quinoxalyl Cp systems have been prepared using Pd-catalyzed coupling with zincated Cp-metal complexes. The new ligands comprise two N-donor atoms; one of them is located in a distal position relative to the metal centre so that it cannot coordinate in a chelating manner. With Cp BTZ ligand derivatives several metal complexes have been synthesized. The new chromium(III) complex CpBTZCrCl2 (12) becomes upon activation an active catalyst for the polymerization of ethylene. Relying on DFT calculations and analysis of spin-density distribution, combined with paramagnetic NMR data a chelating coordination of the CpBTZ ligand is feasible in 12.

Fused pyrazino[2,3-b]indolizine and indolizino[2,3-b]quinoxaline derivatives; synthesis, structures, and properties

The synthesis of six new compounds incorporating either a pyrazino[2,3-b]indolizine or indolizino[2,3-b]quinoxaline core are reported in good yield (58-87%). The intermediates for the key cyclization reaction for one set of compounds (5a-c), with a sterically demanding 3,5-dimethylpyrazole group in the 5-position of the core, were found to be mono-substituted. These intermediates could be isolated and cyclized by heating under acid-catalyzed conditions. To further demonstrate the versatility of the chemistry, compounds 6a-c were synthesized in 58-68% yields. Compounds 5a-c are non-planar in solution and the solid-state, while 6a-c have close to planar conformations, pointing to weak hydrogen bonds between the acidic C-Hs and the adjacent azine nitrogen atoms. The cytotoxicity of the six newly synthesized and three previously prepared compounds was assessed against a human glioblastoma multiforme cell line.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of 2,3-Dichloro-6,7-dimethylquinoxaline, you can also check out more blogs about63810-80-0

Design, synthesis and biological evaluation of type-II VEGFR-2 inhibitors based on quinoxaline scaffold

In an effort to develop ATP-competitive VEGFR-2 selective inhibitors, a series of new quinoxaline-based derivatives was designed and synthesized. The target compounds were biologically evaluated for their inhibitory activity against VEGFR-2. The design of the target compounds was accomplished after a profound study of the structure activity relationship (SAR) of type-II VEGFR-2 inhibitors. Among the synthesized compounds, 1-(2-((4-methoxyphenyl)amino)-3- oxo-3,4 dihydroquinoxalin-6-yl)-3-phenylurea (VIIa) displayed the highest inhibitory activity against VEGFR-2. Molecular modeling study involving molecular docking and field alignment was implemented to interpret the variable inhibitory activity of the newly synthesized compounds.
