Abstract

A novel one-step synthesis of valuable 2,4,5-vinylic-trisubstituted oxazoles is described. This reaction, utilizing readily available β,β-dibrominated secondary enamides and terminal alkenes as starting materials, occurs via a ligand-free Palladium-catalyzed cascade intramolecular CO coupling/intermolecular Heck reaction.
