An efficient sodium bicarbonate promoted aerobic oxidation reaction to prepare N-monosubstituted α-keto amides in the presence of n-tetrabutylammonium hydrogensulfate (TBAHS) was described. This reaction provides a very simple and convenient synthetic route to N-monosubstituted α-keto amides from easily available aryl- or heteroarylacetamides in good to high yields without using toxic reagents and
描述了一种有效的碳酸氢钠促进的需氧氧化反应,以在正丁基硫酸氢铵(TBAHS)存在下制备N-单取代的α-酮酰胺。该反应提供了一种非常简单和方便的合成路线,可以容易地从芳基或杂芳基乙酰胺以高产率到高产率合成N-单取代的α-酮酰胺,而无需使用有毒试剂和苛刻的条件。
