Tang, Nana published the artcilePractical, metal-free remote heteroarylation of amides via unactivated C(sp3)-H bond functionalization, Application of (2-Bromoethyl)cyclopentane, the publication is Chemical Science (2019), 10(28), 6915-6919, database is CAplus and MEDLINE.
A new, efficient, site-selective heteroarylation of amides via C(sp3)-H bond functionalization. Amidyl radicals were directly generated from the amide N-H bonds under mild conditions, which triggered the subsequent 1,5-HAT process. A wide scope of aliphatic amides including carboxamides, sulfonamides and phosphoramides were readily modified at remote C(sp3)-H bonds by installing diverse heteroaryl groups. Borne out of pragmatic consideration, this protocol was used for the late-stage functionalization of amides.
