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 ...
