Synthesis of 2-(Quinoxalin-2-yl)acetamides and Their Preliminary Cytotoxic and Antibacterial Activity. [PDF]

open access: yesChem Biodivers
ABSTRACT Quinoxaline is an aza‐heterocycle found in some bioactive compounds. Thus, to enhance the pharmacological scope of this nucleus, we report a series of 19 acetamides decorated with a quinoxaline core. The synthesis involved the linkage of previously constructed bromoacetamides and hydroxyphenyl quinoxalines via an SN2 reaction. The first series

Bis[2-(thiophen-2-yl)quinoxaline-κN4]silver(I) perchlorate

open access: yesIUCrData, 2023
The crystal of the title salt, [Ag(C12H8N2S)2]ClO4, has C2/c symmetry whereby the silver(I) atom sits on a twofold rotation axis, as does the perchlorate anion, which is disordered about this axis.

Quinoxaline-2-carbonitrile [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2009
In the title compound, C9H5N3, the quinoxaline ring is essentially planar, with a maximum deviation of 0.012 (1) Å. Short inter­molecular distances between the centroids of the 2,3-dihydro­pyrazine and benzene rings [3.6490 (5) Å] indicate the existence of π⋯π inter­actions.

Microwave assisted synthesis of quinoxaline derivatives

open access: yesResults in Chemistry, 2023
Substituted quinoxalines are known building blocks for compounds with pharmacological, agricultural, and material uses. Forming carbon-heteroatom bonds at the 2,3-positions on quinoxaline can be challenging. 2,3-chloroquinoxaline can undergo nucleophilic

2-(4-Chloroanilino)quinoxaline [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2008
There are two mol-ecules in the asymmetric unit of the title compound, C(14)H(10)ClN(3), with dihedral angles of 5.11 (10) and 13.61 (10)° between the aromatic ring systems. In the crystal structure, mol-ecules are linked by N-H⋯N hydrogen bonds, resulting in chains propagating in [010].
