Abstract

In a radical-mediated strategy for β C-H amination of alcohols, imidates as radical relay chaperones serve as traceless directors that facilitates selective C-H functionalization via 1,5-hydrogen atom transfer (HAT) and enable net incorporation of ammonia at the β carbon. A streamlined protocol enables rapid conversion of alcohols to their β-amino analogs (via in situ conversion of alcohols to imidates, directed C-H amination, and hydrolysis).
