Highly Selective 1,6‐Addition of Aryl Boronic Acids to α,β,γ,δ‐Unsaturated Carbonyl Compounds Catalyzed by an Iridium Complex

Perfect control: The catalytic 1,6-addition of aryl boronic acids to electron-deficient dienes was realized by use of an iridium catalyst (see scheme). High yields of the corresponding δ-arylated carbonyl compounds were obtained with perfect 1,6-selectivity.
