get‐together! A RhIII‐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
烯烃在一起!开发了Rh III催化的不同烯烃的氧化交叉偶联反应,从而形成了有价值的线性丁二烯产物,尤其是二不饱和α-氨基酸衍生物。1,1-二,1,2-二和1,1,2-三取代的烯烃可以与苯乙烯和丙烯酸酯偶联。在这些反应中,获得了很高的化学,区域和立体选择性,这使其成为一种有价值的合成工具。
