Alkynyl- and Dialkynyl-quinoxalines. Synthesis of Condensed Quinoxalines

Condensation of 2-chloro- and 2,3-dichloroquinoxalines 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 hydrogen-bonded enol form.Condensation of the alkynylquinoxalines with diethyl sodiomalonate, and related compounds, yields pyridoquinoxalin-4-one derivatives. 2-Alkynyl-3-chloroquinoxalines are intermediates for convenient syntheses of pyrroloquinoxalines.
