functionalization of aliphatic amine was developed. The method is based on a reaction that yields enamine directly from the corresponding aliphatic amine, which otherwise requires the aid of metallic reagent and/or external oxidant. The reaction is operationally simple, general, and highly efficient in functionalizing both cyclic and acyclic amines. Structurally diverse unsaturated imines were obtained from N-heterocycles
开发了一种无金属的脂肪胺直接β-C(sp 3)-H官能化方法。该方法基于直接从相应的脂族胺产生烯胺的反应,否则该反应需要金属试剂和/或外部氧化剂的帮助。该反应操作简单,通用,并且在官能化环状和非环状胺方面都非常有效。从N-杂环获得结构多样的不饱和亚胺,而无环胺则提供具有出色E / Z-选择性的2-烷基肉桂醛和苯并吡喃衍生物。
