2-Phenylthieno[2,3-b]quinoxaline

Acta Crystallographica Section E Structure Reports Online, 2012
The title compound, C(16)H(10)N(2)S, is almost planar (r.m.s. deviation for all non-H atoms = 0.080 Å). The dihedral angle between the three fused-ring system and the phenyl ring is 9.26 (3)°. The S atom and the opposite C atom of the thio-phene ring are mutually disordered with an occupancy ratio of 0.7706 (19):0.2294 (19).

Oxidant-free annulation of α-hydroxy ketones with diamines using aluminum(III) chloride: A supramolecular approach for practical quinoxaline synthesis

Results in Chemistry
The conventional reaction of α-hydroxy ketones (acyloins) with arene-1,2-diamines typically requires an oxidant to facilitate a tandem oxidative condensation, resulting in quinoxaline derivatives. In this study, an innovative approach has been introduced
