RhIII-Catalyzed Oxidative Olefination of Vinylic C[BOND]H Bonds: Efficient and Selective Access to Di-unsaturated α-Amino Acid Derivatives and Other Linear 1,3-Butadienes

Olefin(s) get-together! A Rh^III-catalyzed oxidative cross-coupling of different olefins was developed, resulting in the formation of valuable linear butadiene products and especially di-unsaturated α-amino acid derivatives. 1,1-Di-, 1,2-di-, and 1,1,2-trisubstituted olefins could be coupled with styrenes and acrylates. In these reactions, remarkably high levels of chemo-, regio-, and stereoselectivity were obtained, rendering this a valuable synthetic tool.
