A metal-free oxidative coupling of methyl ketones and primary or secondary amines to α-ketoamides has been developed. Four intermediates, α-iodoketone, α-aminoketone, iminium intermediate, and α-hydroxy amine have been identified through a series of control experiments. The atom-economic methodology can be scaled-up, tolerates a variety of functional groups, and is operationally simple.
已经开发出甲基酮和伯或仲胺与α-酮酰胺的无金属氧化偶联。通过一系列对照实验,已鉴定出四种中间体,即α-碘酮,α-氨基酮,亚胺鎓中间体和α-羟胺。原子经济方法可以扩大规模,可以容忍各种官能团,并且操作简单。
