A novelpalladium-catalyzed intramolecular aerobic oxidative allylic C−H amination of olefins has been developed. Brønsted base can modulate the regioselectivity, favoring the formation of 7-membered rings. Mechanistic studies using deuterium-labeled substrates as probes support a rate-determining allylic C−H activation/irreversible reductive elimination pathway.

A new and mild palladium(II)-catalyzed reaction for the intramolecular acyloxylation/cyclization of 2-(3'-alkenyl)indoles was developed. The newly formed cycles involve oxygen-containing functionalized groups, which might be transferred further to provide other indole derivatives.
