Abstract
Ionic liquid-catalysed oxygenation of quinoxalin-2(1H)-one utilizing aerobic oxygen as a green oxidant under visible light conditions at room temperature has been described. Various N-1-alkyl and aryl-substituted quinoxalin-2(1H)-ones provided good yields of the desired products. The ionic-liquid tetramethylammonium hydroxide (TMAH) employed is readily available and promotes the oxygenation under additive and base-free conditions. The present procedure illustrates the applicability at gram scale reactions and showcases the subsequent conversion of the target product into glycogen phosphorylase inhibitors.

NJC (New Journal of Chemistry) is a broad-based primary journal encompassing all branches of chemistry and its sub-disciplines. It contains full research articles, communications, perspectives and focus articles. This well-established journal, owned by the Centre National de la Recherche Scientifique (CNRS) of France, has been co-published with the Royal Society of Chemistry since January 1998. NJC is the forum for the publication of high-quality, original and significant work that opens new directions in chemistry or other scientific disciplines. In addition to having a significant chemical component, work published in NJC must demonstrate that it will have an impact on areas of research other than that of the reported work.
