In this paper, we demonstrate a metal-free asymmetric hydrogenation of acyclic α,β-unsaturated ketones under the catalysis of a frustratedLewispair (FLP) comprising chiral oxazoline and achiral borane. A wide range of optically active α-substituted ketones were furnished in high yields with 26–85% ee’s.
在本文中,我们展示了在包含手性恶唑啉和非手性硼烷的受挫路易斯对(FLP)的催化下,无环α,β-不饱和酮的无金属不对称氢化。以高产率提供了多种光学活性 α-取代酮,其 ee 为 26-85%。
