A novel and efficient double-carbonylation of indoles with primary or secondary amines to yield indole-3-α-ketoamides has been developed and bioactive molecules could be one-pot synthesized using the current methodology, which could also be selectively switched to mono-carbonylation to afford indole-3-amides only by a slight modification of reaction conditions.

A palladium-catalyzeddirect dehydrogenative annulation (DDA) of indolecarboxamides with internal alkynes via C−H and N−H bond cleavage usingair as the oxidant was developed. With this method, both β- and γ-carbolinones can be easily prepared under the mild conditions.
