An efficient and general method for the synthesis of functionalized α,α-dihaloimines via halogenation of N-substituted enaminoesters and enaminones is described. This reaction, in which both α,α-dihaloimines and mixed α,α-dihaloimines could be achieved in good to excellent yields, is believed to proceed via an α-monohalogenated enamine intermediate. This synthetic method features no use of transition
描述了一种通过卤化 N-取代的烯胺酯和烯胺酮来合成功能化 α,α-二卤代胺的有效且通用的方法。该反应可以通过 α-单卤代烯胺中间体进行,其中 α,α-二卤代胺和混合 α,α-二卤代亚胺的产率都很高。该合成方法不使用过渡金属,底物易得,反应条件温和,操作简单安全,可实现克级合成。此外,产品的合成效用通过它们有效地转化为进一步有用的含氮杂环和结构单元来证明。
