The enantioselective Cu‐catalyzed 1,6‐boration of (E,E)‐α,β,γ,δ‐unsaturated ketones is described, which gives homoallylic boronates with high enantiomeric purity and unexpectedly high Z‐selectivity. By changing the solvent, the outcome can be altered to give E‐allylic boronates.
描述了(E,E)-α,β,γ,δ-不饱和酮的对映选择性Cu催化的1,6-硼酸酯,它使对映体硼酸酯具有高对映体纯度和出乎意料的高Z选择性。通过改变溶剂,可以改变结果,得到E-烯丙基硼酸盐。
