γ,δ,ε-C(sp(3))-H Functionalization through Directed Radical H-Abstraction.

Tao Liu1, Tian-Sheng Mei1, Jin-Quan Yu1.   

Abstract

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-n class="Chemical">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 amines.
