摘要

The catalyst-free one-pot synthesis of quinoxaline-2-carboxylate is reported by the reaction of α-halo-β-ketoesters with 1, 2-diamines using an ionic liquid as an environmentally benign solvent. The recovered ionic liquid was reused for four to five cycles. Moreover, the method is applicable for a variety of 1, 2-diamines and α-halo-β-ketoesters.
