General and efficient methods allow the synthesis of 2-oxazolones and α-aminoketones from β,β-dibromoenamides depending on the choice of R groups and the reaction conditions. On the basis of mechanistic studies, both reactions proceed via an intermolecular Suzuki-Miyaura C-C coupling and an intramolecular C-O coupling.
