A ruthenium-catalyzed alkyne oxidation to 1,2-diketones using Oxone under room temperature is reported. Both substrate scope and mechanism were discussed. Notably, combination of the alkyne oxidation and condensation cyclization in one pot offers a very efficient and convenient entry into quinoxaline derivatives.
据报道,在室温下使用Oxone将钌催化的炔烃氧化为1,2-二酮。讨论了底物的范围和机理。值得注意的是,炔烃氧化和缩合环化的组合在一锅中提供了非常有效和方便的喹诺沙林衍生物。
