Al and friends: Asymmetric conjugate addition of Me3Al to β,β‐disubstituted α,β‐unsaturated ketones in the presence copper and L1 leads to a highly efficient construction of an all‐carbon‐substituted chiral quaternary center. This result is the first example of an asymmetric conjugate addition of Me3Al to acyclic enones to give a chiral quaternary carbon center with excellent yield and enantioselectivity
Al和朋友:在铜和L1存在下,Me 3 Al不对称地共轭添加到β,β-二取代的α,β-不饱和酮中,导致高效构建全碳取代的手性季中心。该结果是在温和的反应条件下将Me 3 Al不对称共轭加成到无环烯酮上以得到具有优异收率和对映选择性的手性季碳中心的第一个例子。
