efficient synthesis of a variety of [1,2,3]triazolo-[1,5-a]quinoxalin-4(5H)-ones via a [3 + 2] cyclization
reaction by photoredox catalysis between quinoxalinones and hypervalent
iodine(III) reagents is reported. A range of quinoxalinones and hypervalent
iodine(III) reagents were tolerated well. This cyclization reaction
allows access to structurally diverse [1,2,3]triazolo-[1,5-a]quinoxalin-4(5H)-ones in moderate to
good yields.
