An efficient method to construct azapolycycles via directing group participated benzylic C(sp3)-H/C(sp2)-H cross-dehydrogenative coupling reactions is described. The reaction proceeded through a palladium catalyzed C(sp3)-H activation followed by coupling with a C(sp2)-H bond of quinoline to afford the azapolycyclic compounds. The reaction works with a broad substrate scope affording the products in moderate to good yields with excellent diastereoselectivities. Control experiments further supported the proposed mechanism.

A general alkylation protocol for substituted iodopyridines was developed (32 examples, 44-97% yield). The reaction is based on the Pd(II)-catalyzed C-H activation of 8-aminoquinoline-derived alkanoic amides and it employs a catalyst cocktail of Pd(OAc)2 (10 mol%), NaI (30 mol%), and (BuO)2POOH (20 mol%), with Ag2CO3 as base.
