  Design, synthesis, and application of novel chiral ONN ligands for asymmetric alkylation

  摘要：

  Starting from easily available chiral pool amino alcohols, a set of novel chiral ONN ligands was synthesized and their catalytic potential was examined in asymmetric alkylation. Ligands with a secondary central NH group and N-methylated ONN ligands were successfully applied as catalysts in the addition of diethyl zinc to various aromatic aldehydes, yielding secondary alcohols in excellent yields of up to 99 % ee.

• Enantioselective Alkylation of Aldehydes with Diethylzinc Catalyzed by C₂-Symmetric Ligands
  作者：David Williams、Mark Fromhold

  DOI：10.1055/s-1997-6125

  日期：1997.6

  The C2-symmetric pyridine 1, incorporating two units of (-)-ephedrine, is an effective catalyst for the enantioselective reactions of diethylzinc with a series of aromatic aldehydes. The propanol products possess the S-configuration. This result is a significant reversal of stereochemistry based upon literature precendents and our direct comparisons with reactions catalyzed by the corresponding C2-symmetric xylene 2.

  C2对称的吡啶1，包含两个(-)-麻黄碱单元，是二乙基锌与一系列芳香醛的手性选择性反应中有效的催化剂。所得到的丙醇产品具有S配置。这个结果与文献中的前例以及我们与相应的C2对称二甲苯2催化的反应进行直接比较后，展现出了显著的立体化学逆转。

  Titanium(IV) complexes of bidentate trans-cyclohexane 1,2-diamine-based unsymmetrical chiral bis(sulfonamide) ligands were evaluated as catalysts for the asymmetric addition of diethylzinc to aldehydes. The reaction provided secondary alcohols in quantitative yields and very good enantioselectivity (up to 96% ee).
