摘要
在二甲亚砜作用下,α-卤代酮与芳香1,2-二胺反应,得到较高产率的喹喔啉衍生物.结果表明反应经历一个串联的氧化-缩合过程.二甲亚砜现场氧化α-卤代酮,生成的二羰基化合物与芳香1,2-二胺缩合成喹喔啉衍生物.
In the presence of DMSO, the reaction of α-haloketones with aromatic 1,2-diamines afforded quinoxalines in moderate to high yields. The results disclosed that it was a one-pot tandem oxidation-condensation procedure. The DMSO-mediated in-situ oxidation of the α-haloketone leads to the dicarbonyl compound which is immediately trapped by the aromatic 1,2-diamine.
