Aliphatic amides are selectively functionalized at the γ- and δ-positions through directed radical 1,5 and 1,6 H-abstractions, respectively. The initially formed γ- or δ-lactams are intercepted by N-iodosuccinimide and trimethylsilyl azide, leading to double and triple C-H functionalizations at the γ-, δ-, and ε-positions. This new reactivity is exploited to convert alkyls into amino alcohols and allylic
脂肪族酰胺分别通过定向自由基 1,5 和 1,6 H-抽象在 γ- 和 δ- 位选择性地官能化。最初形成的γ-或δ-内酰胺被N-碘代琥珀酰亚胺和三甲基甲硅烷基叠氮化物拦截,导致γ-、δ-和ε-位的双和三CH官能化。这种新的反应性被用来将烷基转化为氨基醇和烯丙胺。
