3,4-DIHYDROQUINOXALIN-2-ONES: RECENT ADVANCES IN SYNTHESIS AND BIOACTIVITIES

Abstract

A summary of recent synthetic approaches to 3,4-dihydroquinoxalin-2-ones is discussed herein along with highlights of biological activity. The synthetic approaches include access to enantiopure 3,4-dihydroquinoxalin-2-ones from chiral pool amino acids via coupling/cyclization, Michael addition/cyclization cascades, 3,3-disubstituted systems from multicomponent couplings, Bargellini reaction, or photochemical reduction.
