  Enantioselective synthesis of chiral 1,2-diamines by the catalytic ring opening of azabenzonorbornadienes: application in the preparation of new chiral ligands

  摘要：

  In the presence of a rhodium catalyst (5 mol %) generated in situ from [Rh(cod)C]12 and (S,S')-(R,R')-C-2-ferriphos-tolyl, the asymmetric ring-opening reaction of N-Boc-azabenzonorbornadienes with dibenzylamine proceeded with excellent enantioselectivity (up to > 99% ee) to give the corresponding 1,2-diamine scaffolds in high yields. The sequential deprotection of the ring-opened products and treatment with tartaric acid gave the enantiomerically pure 1.2-diamine tartrate salts. These salts were used for the preparation of new chiral ligands Such as the salen-type ligands and Trost-type ligands, (c) 2006 Elsevier Ltd. All rights reserved.

• Asymmetric Hydrophosphination of Heterobicyclic Alkenes: Facile Access to Phosphine Ligands for Asymmetric Catalysis

  Asymmetric hydrophosphination is the most atomically economical and straightforward approach to the construction of chiral organophosphorus compounds. Good stereoselectivities have been achieved in asymmetric hydrophosphination of an electron-deficient C═C double bond, but substrates involving nonpolar C═C bonds remain difficult and are rarely tackled. Herein, we report asymmetric hydrophosphination

  不对称氢磷酸化是手性有机磷化合物构建中最原子经济且最直接的方法。在缺乏电子的C═C双键的不对称加氢磷化反应中已经获得了良好的立体选择性，但是涉及非极性C═C键的底物仍然很困难，而且很少解决。在本文中，我们报道了非电子活化的双键的非对称氢磷酸化，其立体控制程度非常高。该策略为制备高产率（高达99％的产率）和对映选择性（高达ee的99％）的叔膦提供了一个方便且广泛适用的平台。

  The complexes of various Rh precusors with ferrocenyl chiral ligand (R,S)-Cy2PF-PPh2 were found effective catalysts for the asymmetric hydroalkynylation reaction of norbornadiene derivatives. When RhCl3·3H2O was employed, good yields (up to 98%) and high enantioselectivities (up to >99.9% ee) could be obtained for the reactions of a broad scope of substrates.

  AbstractA chiral palladium/copper (Pd/Cu) co‐catalytic system which could enable asymmetric ring opening reaction of azabenzonorbornadienes with terminal alkynes is reported. This system comprises palladium(II) acetate [Pd(OAc)2]/(R)‐xyl‐Binap and copper(I) triflate (CuOTf). A good substrate scope was found, with excellent enantioselective outcomes (up to >99.9 % ee). A reaction mechanism involving two metal complexes is also proposed.magnified image
