title: Brønsted base-modulated regioselective pd-catalyzed intramolecular aerobic oxidative amination of alkenes: formation of seven-membered amides and evidence for allylic C-H activation.
abstract: A novel palladium-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.
