Copper-catalyzed oxidative coupling of quinoxalin-2(1<i>H</i>)-ones with alcohols: access to hydroxyalkylation of quinoxalin-2(1<i>H</i>)-ones

Abstract

An efficient protocol for the synthesis of hydroxyl-containing quinoxalin-2(1<italic>H</italic>)-ones has been developed <italic>via</italic> the copper-catalyzed cross-coupling reaction of quinoxalin-2(1<italic>H</italic>)-ones with alcohols with moderate to good yields.
