• Triflimide: An Overlooked High-Performance Catalyst of the Mukaiyama Aldol Reaction of Silyl Ketene Acetals with Ketones
  作者：Han Yong Bae、Benjamin List

  日期：2018.9.18

  The Mukaiyama aldol reaction is a widely applied carbon–carbon bond forming reaction. However, despite numerous well‐established methods using aldehydes as acceptors, only few examples exist with ketones. Here we report a highly practical catalytic approach to this transformation, namely, the triflimide catalyzed Mukaiyama aldol reaction of silyl ketene acetals with ketones. This method exhibits a

  Mukaiyama羟醛反应是一种广泛应用的碳-碳键形成反应。但是，尽管有许多使用醛作为受体的公认方法，但酮的例子很少。在这里，我们报告了一种非常实用的催化方法来进行这种转化，即三氟甲酰亚胺催化的甲硅烷基乙烯酮缩醛与酮的Mukaiyama aldol反应。该方法具有广泛的底物范围，非常快，可耐受功能化底物，并且仅需百万分之几的催化剂负载量即可进行制备级反应，纯度高达数百克（纯度> 99％）。
• Iron-Catalysed Reformatsky-Type Reactions
  作者：Muriel Durandetti、Jacques Périchon

  DOI：10.1055/s-2006-926432

  日期：2006.5

  A Reformatsky-type reaction has been developed using iron catalysis in acetonitrile or DMF. Reduction of iron(II) bromide by manganese metal in acetonitrile provides a low-valent iron catalyst, which is the active species; under these conditions, α-chloroesters or nitriles can both be converted into their corresponding derivatives. The method was applicable to both ketones and aldehydes, resulting in the formation of β-hydroxyesters under mild conditions.

  一种 Reformatsky 型反应已采用铁催化体系在乙腈或二甲基甲酰胺中得到开发。通过在乙腈中用锰金属还原二溴化铁，可得到低价铁催化剂，该催化剂为活性物种；在这些条件下，α-氯酯或腈均可转化为相应的衍生物。该方法适用于酮和醛，在温和条件下形成 β-羟基酯。
• Ni-catalyzed activation of α-chloroesters: a simple method for the synthesis of α-arylesters and β-hydroxyesters
  作者：Muriel Durandetti、Corinne Gosmini、Jacques Périchon

  日期：2007.1

  Coupling reactions of α-chloroesters with aryl halides (α-arylation) or carbonyl compounds (Reformatsky) using nickel catalyst allow, under mild conditions, the preparation of various functionalized aryl propionic acid derivatives or β-hydroxyesters. In the synthesis of aryl propionic acid derivatives, the process is efficient with aryl halides bearing either electron-withdrawing or electron-donating

  使用镍催化剂，α-氯酸酯与芳基卤化物（α-芳基化）或羰基化合物（Reformatsky）的偶联反应可以在温和的条件下制备各种官能化的芳基丙酸衍生物或β-羟基酯。在芳基丙酸衍生物的合成中，该方法对于带有带吸电子基团或给电子基团的芳基卤化物是有效的。

  日期：2013.4

  Copper hydride‐catalyzed conjugate reduction‐intermolecular aldol addition domino reactions were realized using α,β‐unsaturated carboxylates as hydride acceptors and a silane as the reducing reagent. High diastereoselectivities were achieved with 4,5‐bis(diphenylphosphino)‐9,9‐dimethylxanthene as the ligand and tert‐butyl acrylate as the hydride acceptor.

  An asymmetric reductive aldol-type reaction of α,β-unsaturated esters with carbonyl compounds using Rh catalyst and Et2Zn was investigated. A chiral zinc complex from α,β-unsaturated ester was easily generated as the key intermediate from Et2Zn and Wilkinson's catalyst with diisopropyl L-(+)-tartrate to give a variety of enantioenriched β-hydroxy esters. The reaction was also applied to the intramolecular

  研究了Rh催化剂和Et2Zn对α，β-不饱和酯与羰基化合物的不对称还原醛醇型反应。由Et2Zn和Wilkinson's催化剂与L-（+）-酒石酸二异丙酯形成的关键中间体很容易生成由α，β-不饱和酯形成的手性锌络合物，从而得到各种对映体富集的β-羟基酯。该反应还用于分子内还原性醛醇缩环化。
