Abstract

Biologically interesting fused oligocyclic lactams have been prepared via an intramolecular redox-neutral cyclization process. By the proper choice of the substrates with a wide variety of tethered olefins, the less favored C-H bond can be activated and functionalized. This C-H activation proceeds under mild conditions, obviates the need for external oxidants, and displays a broad scope with respect to the substituents.
