An efficient palladium(II)-catalyzed regioselective asymmetric 1,4-conjugate addition of arylboronic acids to linear α,β,γ,δ-unsaturated ketones is developed using phosphapalladacycle catalysts. The relevant 1,4-products were obtained exclusively with perfect regioselectivity, appreciable yields, and enantioselectivities. A wide range of dienone substrates as well as substituted arylboronic acids are
使用磷钯环催化剂开发了一种有效的钯 (II) 催化的区域选择性不对称 1,4-共轭加成芳基硼酸到线性 α,β,γ,δ-不饱和酮。以完美的区域选择性、可观的产率和对映选择性专门获得了相关的 1,4-产物。在室温下进行的该协议中可以容忍多种二烯酮底物以及取代的芳基硼酸。
