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.
手性铜催化的(E,E)-α,β,γ,δ-不饱和酮的 1,6-硼化反应被描述,该反应以高对映纯度和出人意料的高 Z-选择性得到偕烯丙基硼酸酯。通过改变溶剂,可以改变反应结果得到 E-烯丙基硼酸酯。
