  POLYNORBORNENE/CARBON BLACK-CROSS-LINKED THREE-DIMENSIONAL NETWORK-IMMOBILIZED COPPER/GOLD (PNBI/CB-Cu/Au) NANOCATALYST, AND PREPARATION METHOD AND USE THEREOF

  摘要：

  The present disclosure belongs to the technical field of catalyst preparation, and provides a polynorbornene/carbon black-cross-linked three-dimensional network-immobilized bimetallic copper/gold (PNBI/CB-Cu/Au) nanocatalyst, and a preparation method and use thereof. Metallic copper and gold both exist in a form of nanoparticles in the catalyst and are uniformly dispersed, and further enhancing a catalytic performance. Moreover, the carrier is a polynorbornene/carbon black-cross-linked three-dimensional network, and a relative content of free hydroxyl groups in the catalyst is controlled by changing a monomer ratio to adjust a hydrophilic-lipophilic balance value of the catalyst, adapting to a reaction of an organic phase with an aqueous phase. Furthermore, the catalyst is insoluble in conventional solvents, and has a desirable effect in immobilizing nanoscale metallic copper, prolonging a service life of the catalyst.

• Kinetic Resolution of β-Hydroxy Carbonyl Compounds via Enantioselective Dehydration Using a Cation-Binding Catalyst: Facile Access to Enantiopure Chiral Aldols

  β-hydroxy carbonyl (aldol) compounds through enantioselective dehydration process was developed using a cation-binding Song’s oligoethylene glycol (oligoEG) catalyst with potassium fluoride (KF) as base. A wide range of racemic aldols was resolved with extremely high selectivity factors (s = up to 2393) under mild reaction conditions. This protocol is easily scalable. It provides an alternative approach for

  通过使用阳离子结合的宋氏低聚乙二醇（oligoEG）催化剂，以氟化钾（KF）为基础，开发了通过对映选择性脱水过程开发的外消旋β-羟基羰基（aldol）化合物的实用且高度对映选择性的非酶动力学拆分方法。在温和的反应条件下，极高的选择性因子（s =高达2393）可分离出多种外消旋醇醛。该协议易于扩展。它为合成对映体纯形式的多种生物学和药学上相关的手性醇醛提供了另一种方法。例如，外消旋姜醇可以以极高的效率（s> 240），在一个步骤中同时提供对映体纯的姜黄醇和相应的Shogaols。这种动力学拆分过程的显着效果可归因于在由手性催化剂，底物和KF产生的密闭超分子手性笼中的系统协同氢键催化。

  Direct asymmetric aldol reaction of aryl ketones with aryl aldehydes catalyzed by chiral metal complex is reported for the first time herein. Two novel semicrown chiral ligands 1a and 1b were synthesized from (S)- and (R)-BINOL, respectively, and then employed to catalyze the direct asymmetric aldol addition of aryl ketones to aryl aldehydes. Introduced with 2.0 equiv of diethylzinc, 1b had higher

  本文首次报道了手性金属络合物催化的芳基酮与芳基醛的直接不对称醛醇缩合反应。分别从（S）-和（R）-BINOL合成了两个新颖的半冠手性配体1a和1b，然后用于催化芳基酮与芳基醛的直接不对称羟醛加成。引入2.0当量的二乙基锌后，1b的对映选择性高于1a。获得了高达97％的产率和高达80％的对映选择性。

  Chiral Al/Zn heterobimetallic complexes are effective catalysts for the direct highly enantioselective aldol reaction of acetophenones with aromatic aldehydes. The Al site in the complex acts as a Lewis acid to activate aldehyde, whereas ethylzinc alkoxide plays a role of a Brønsted base to form a reactive zinc enolate with acetophenone. Distinct nature of two different metals contributes to the efficient

  手性Al / Zn异双金属配合物是苯乙酮与芳族醛直接高对映选择性醛醇缩合反应的有效催化剂。络合物中的Al位点起路易斯酸的作用来活化醛，而乙基锌醇盐起布朗斯台德碱的作用，与苯乙酮形成反应性烯醇锌。两种不同金属的不同性质有助于有效的直接不对称醛醇缩合反应。
• <i>N</i>-Triflylthiophosphoramide Catalyzed Enantioselective Mukaiyama Aldol Reaction of Aldehydes with Silyl Enol Ethers of Ketones
  作者：Cheol Hong Cheon、Hisashi Yamamoto

  DOI：10.1021/ol100233t

  日期：2010.6.4

  The first Brønsted acid catalyzed asymmetric Mukaiyama aldol reaction of aldehydes using silyl enol ethers of ketones as nucleophiles has been reported. A variety of aldehydes and silyl enol ethers of ketones afforded the aldol products in excellent yields and good to excellent enantioselectivities. Mechanistic studies revealed that the actual catalyst may be changed from the silylated Brønsted acid

  已经报道了使用酮的甲硅烷基烯醇醚作为亲核试剂的第一个布朗斯台德酸催化醛的不对称 Mukaiyama 羟醛反应。各种醛和酮的甲硅烷基烯醇醚以优异的产率和良好的对映选择性提供了醛醇产物。机理研究表明，实际的催化剂可能会根据反应温度从甲硅烷基化布朗斯台德酸变为布朗斯台德酸本身。
