A green and mild protocol for the dehydrogenative olefination of cyclicenaminones was devised via palladium catalysis at roomtemperature using oxygen as the terminal oxidant. The synthetic utility of the olefinated cyclicenaminones afforded a series of unique 1,3,5‐trisubstituted benzenes via an unanticipated Diels–Alder tandem reaction. The broad substrate scope and good yields achieved with this
