  内环烯酮的对映选择性加氢：历史问题的解决方案†

  摘要：

  内环烯酮的对映选择性氢化一直是均相催化的历史问题。我们在本文中报道了一种用分子氢还原内环烯酮的有效方法。在铑/ Zhaophos配合物的催化下，具有五，六或七元环的各种烯酮以高对映选择性（92％-99％ee）氢化。出色的化学和对映选择性证明了该方法已成功地用于柠檬醛的对映选择性加氢，以生产对映体富集的香茅醛。

• Highly Practical Catalytic Asymmetric 1,4-Addition of Arylboronic Acids in Water Using New Hydrophilic Chiral Bicyclo[3.3.0] Diene Ligands
  作者：Chen-Guo Feng、Zhi-Qian Wang、Cheng Shao、Ming-Hua Xu、Guo-Qiang Lin

  The first Rh-diene-catalyzed aqueous asymmetric 1,4-addition of alpha,beta-unsaturated carbonyl compounds with arylboronic acids has been realized. By using a hydrophilic bicyclo[3.3.0] diene ligand, the reactions can be performed successfully in neat water at room temperature to afford the corresponding products in good yields and with very high enantioselectivities for both cyclic and linear substrates

  pseudo-enantiomeric olefin ligands were designed from d-glucose and d-galactose. These ligands yield consistently excellent levels of enantioselectivity in Rh(I)-catalyzed 1,4-additions of aryl- and alkenylboronic acids to achiral enones and high diastereoselectivity with chiral substrates. Contrary to established olefin ligands, they are obtained enantiomerically pure via short syntheses without racemic

  由d-葡萄糖和d-半乳糖设计了高效的假对映体烯烃配体。这些配体在Rh（I）催化的芳基和烯基硼酸向非手性烯酮的1,4-加成反应中始终产生优异的对映选择性，并具有手性底物的高非对映选择性。与已建立的烯烃配体相反，它们是通过短合成法得到对映体纯的，没有外消旋拆分步骤，这使它们成为具有烯烃供体位点的手性配体的重要补充。

  A new practical method for the asymmetric Michael addition of arylboronic acids to α,β-unsaturated carbonyl compounds utilizing in situ generated chiral rhodium-binap-based catalyst has been developed to address the unavailability of the preformed catalysts. While maintaining high levels of enantioselectivity reported for the preformed catalysts, the new method provides a convenient access to either

  C2-Symmetric bicyclo[2.2.2]octa-2,5-dienes containing benzyl, phenyl, and substituted phenyl groups at 2 and 5 positions were prepared enantiomerically pure by way of bicyclo[2.2.2]octane-2,5-dione as a key intermediate. These chiral diene ligands were successfully applied to rhodium-catalyzed asymmetric 1,4-addition of arylboronic acids to α,β-unsaturated ketones. High enantioselectivity (up to 99%
