摘要

手性 SPINOL 衍生的硼磷酸盐实现了外环 α、β-不饱和酮的不对称 1,4-还原，从而形成了多种具有光学活性的 α-取代的四氢萘酮。该反应的对映活性决定性步骤是高活性硼烯酸盐中间体的质子化。由衍生自手性 SPINOL 的硼磷酸盐和频哪醇硼烷组成的催化还原体系可广泛用于其他不对称还原反应。

Chiral SPINOL-derived Boro-phosphate-Catalyzed Asymmetric 1,4-Reduction of Exocyclic α,β-Unsaturated Ketones

An asymmetric 1,4-reduction of exocyclic α,β-unsaturated ketones leading to the formation of diverse optically active α-substituted tetralones has been realized by chiral SPINOL-derived boro-phosphate. The enantios-elctivity-determining step of the reaction is the protonation of a highly active boron enolates intermediate. The catalytic reduction system composed of chiral SPINOL-derived boro-phosphate and pinacolborane may be widely used in other asymmetric reduction reactions.

期刊介绍： Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry. The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
