A new method for the synthesis of conjugated dien- and enamides by palladium-catalyzed coupling reaction of (E)-ß-bromoacrylamides with alkenyl- and alkylboronates is reported. This procedure provided some biologically active, naturally occurring unsaturated amides, such as dehydropipernonaline, pipernonaline and other related alkaloids, in one-pot.
