  铜-二吡啶基膦催化的氢化硅烷化：芳基和杂芳基环烷基醇的对映选择性合成†

  摘要：

  首次系统地研究了非贵金属铜催化的各种不同环尺寸的芳基环烷基酮的对映选择性氢化硅烷化（对映体过量高达99％）。结果表明，环烷基的空间大小对反应结果有重要影响。还实现了对映体纯度高达97％的环己基杂芳基醇的选择的首次立体选择性形成。在某些环己基吡啶基酮的还原中，观察到温度对醇产物的对映体纯度和绝对构型都有显着影响。

• Aryl Bromides as Inexpensive Starting Materials in the Catalytic Enantioselective Arylation of Aryl Aldehydes: The Additive TMEDA Enhances the Enantioselectivity

  We used aryl bromides as inexpensive starting materials to enantioselectively arylate aldehydes in one pot. Aryl bromides readily transfer aryls to aryllithiums with n-butyllithium, successively to triarylaluminums with aluminum chloride, and then to aryltitaniums with titanium isopropoxide. Finally aryltitaniums arylate aldehydes catalyzed by (S)-H-8-BINOLTi(Oi-Pr)(2) in excellent yields and enantioselectivities. The additive TMEDA evidently suppresses the racemic background reaction promoted by LiCl generated from salt metathesis. This procedure represents a cost-effective and operationally convenient method for enantioenriched diarylmethanols.
• Highly enantioselective addition of arylzinc reagents to aldehydes promoted by chiral aziridine alcohols

  Enantiomerically pure, chiral secondary and tertiary aziridine alcohols have proven to be highly efficient catalysts for enantioselective asymmetric additions of arylzinc species to aldehydes leading to products in high chemical yields (up to 90%) and with ee's up to 90%. The influence of the stereogenic centers located at the aziridine subunit on the stereochemical course of the reaction is discussed. (C) 2016 Elsevier Ltd. All rights reserved.
