A Pd-catalyzed C4-olefination of oxazoles via C–H bond activation under mild conditions was achieved. The reaction was shown to be general over a range of substrates. New protocols for the divergent transformation of these products to provide functionalizedamino alcohol and aminoacid derivatives have also been established.
