formation reactions are highly important in pharmaceutical, agrochemical and material research. In this article we describe the first copper-catalyzed cross-coupling reaction of thioamides with acceptor/acceptor-substituted and acceptor-only substituted α-diazocarbonyl compounds to yield enaminones. The reaction shows broad substrate scope in terms of thioamides and diazocarbonyl compounds. Primary
在药物,农业化学和材料研究中,开发用于C C键形成反应的操作简单且经济高效的方法非常重要。在本文中,我们描述了硫酰胺与受主/受主取代的和仅受主取代的α-重氮羰基化合物在铜催化下的交叉偶联反应,从而生成烯胺酮。该反应在硫酰胺和重氮羰基化合物方面显示出广泛的底物范围。伯,仲和叔硫酰胺与α-重氮二酯,α-重氮酮酸酯,α-二重氮酮,α-二重氮酮酰胺,α-二重氮酰胺,α-二重氮酮砜和α-二重氮酮反应时均会产生烯胺酮。
