The Ru(II)-catalyzed C-H amidation of indoline at the C7-position en route for synthesizing the 7-amino indole scaffold has been achieved by using dioxazolone, which is an environmentally benign amidating reagent. This protocol paves the way for synthesizing a variety of 7-amino indole derivatives in excellent yields at ambient reaction conditions. The readily cleavable amide group has been utilized as a directing group for the amidation. The derivatives of 7-amino indole are synthetically useful for accessing a variety of natural products, drug molecules, and biologically active compounds.
