Abstract

Abstract Substituted benzene-1, 2-diamine reacted with various α-keto esters at 50 under mild conditions for 15 min using H 2 O as reaction medium, providing a variety of 3- substituted quinoxalinone derivatives in excellent yields. The reaction was instantaneous, and products were isolated by simple filtration.
