Alkynyl- and dialkynyl-quinoxalines. Synthesis of condensed quinoxalines

Journal of the Chemical Society, Perkin Transactions 1, 1980
Condensation of 2-chloro- and 2,3-dichloro-quinoxalines with alk-1-ynes in the presence of bis(triphenylphosphine)palladium(II) dichloride and copper(I) iodide gives mono- and di-alkynylquinoxalines. Addition of amines to these products gives stable enamines; hydration gives 2′-oxoalkyl compounds which exist predominantly in the intramolecularly ...

Structures of quinoxaline antibiotics

Acta Crystallographica Section B Structural Science, 1995
The crystal structures of three quinoxaline antibiotics-echinomycin 2QN, triostin C and the C222(1) form of triostin A--have been determined, and the structure of the P2(1)2(1)2(1) form of triostin A has been re-refined against our previously reported data. The molecular conformations are compared with those deduced from NMR data and those reported for

Quinoxaline-Bridged Porphyrinoids

Journal of the American Chemical Society, 2002
Quinoxaline-bridged porphyrinoids (3), the first macrocycles containing dipyrrolylquinoxaline (DPQ, 1) subunits, were synthesized from the condensation of the diformyl-substituted DPQ derivatives (2) and 1,8-diaminoanthracene. The resulting structures were confirmed by X-ray analyses, which showed encapsulation of CHCl(3) molecules within the columnar ...

Quinoxalines Potential to Target Pathologies

Current Medicinal Chemistry, 2015
The study of quinoxalines has increased immeasurably during the last two decades, due firstly to their relatively simple chemical synthesis, which has generated a vast variety of compounds with diverse structural modifications, and secondly, to the wide therapeutic potential and biological activities exhibited by this family of compounds.
