Trifluoroacetic Acid Mediated One-Pot Synthesis of Furo-Fused Quinoxalines/Pyrazines

A trifluoroacetic acid promoted step-economical one-pot approach to the synthesis of furo-fused quinoxalines/pyrazines by the reaction of 2,3-dichloroquinoxalines/pyrazines with alkynes is described. The reaction involves a selective in-situ Sonogashira c
