摘要：

A novel palladium-catalyzed intramolecular aerobic oxidative allylic C-H amination of olefins has been developed. Bronsted 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.
