γ-disubstituted and β,γ-disubstituted allylic alcohols were prepared and successfully hydrogenated using suitable N,P-based Ir complexes. High yields and excellent enantioselectivities were obtained for most of the substrates studied. This investigation also revealed the effect of the acidity of the N,P–Ir-complexes on the acid-sensitive allylic alcohols. DFT ΔpKa calculations were used to explain the effect of
在这项研究中,制备了一系列的γ,γ-二取代和β,γ-二取代的烯丙醇,并使用合适的基于N,P的Ir配合物成功地进行了氢化。对于大多数研究的底物,均获得了高收率和出色的对映选择性。这项研究还揭示了N,P–Ir配合物的酸度对酸敏感性烯丙基醇的影响。DFTΔP ķ一个计算被用来解释上的相应的铱络合物的酸性的N,P配体的效果。反应的选择性模型用于准确预测氢化醇的绝对构型。
