presence of pinacolborane. This mild process represents a general method to access a wide variety of structurally diverse α‐chiral allylic alcohols in excellent yields and enantioselectivity, as well as very high levels of ambidoselectivity for 1,2‐ over 1,4‐reduction. Furthermore, for reactions on a 10 mmol scale, catalyst loadings as low as 0.5 mol % could be employed to deliver product without any
在松果烷硼烷的存在下,使用NiH催化剂可实现α,β-不饱和酮的对映选择性1,2-还原。这种温和的过程代表了一种获得大量结构多样的α-手性烯丙醇的通用方法,该产品具有优异的收率和对映选择性,并且对1,2-,1,4-还原具有非常高的双键选择性。此外,对于10 mmol规模的反应,可使用低至0.5 mol%的催化剂负载量来输送产物,而对收率,对映体或双歧选择性没有任何不利影响。
