Herein, we report efficient catalysts based on phosphoramidites for the asymmetric copper-catalyzed conjugate addition of Grignard reagents to acyclic α,β-unsaturated ketones. A variety of Grignard reagents can be added to aliphatic and aromatic acyclic enones with good yields and moderate to good enantioselectivities.
在此,我们报道了基于亚磷酰胺的高效催化剂,用于将格氏试剂不对称铜催化的共轭加成到无环α,β-不饱和酮上。可以将各种格氏试剂以良好的产率和中等至良好的对映选择性加入脂族和芳族无环烯酮中。
