Remote Allylation of Unactivated C(sp3)-H Bonds Triggered by Photogenerated Amidyl Radicals.

Bin Xu1, Uttam K Tambar1.   

Abstract

The allylation reaction is a highly versatile transformation in chemical synthesis. While many elegant direct C(sp2)-H allylation reactions have been developed, the direct allylation of unactivated C(sp3)-H bonds is underdeveloped. By applying photoredox catalysis and a [1,5]-HAT process, herein we report a direct allylation of unactivated C(sp3)‒H bonds. This photocatalyzed transformation is tolerant of several functional groups in the amide and allylic chloride substrates. Various allyl-substituted amide products were obtained with good yields and high δ-selectivity.
