  用于一锅三组分曼尼希反应的环保、光控和高度可回收催化剂

  摘要：

  摘要 通过将4-[4-(6-膦酸-己氧基)苯基偶氮基]苯磺酸固定在膦酸锆上，合成了一种环境友好、光控、高度可回收的催化剂(ZrOPPAZOSO 3 H)。该催化剂通过傅里叶变换红外、扫描电子显微镜、X射线粉末衍射、氮吸附-解吸和紫外-可见分析进行了表征。研究了ZrOPPAZOSO 3 H在室温下对水中苯甲醛、苯胺和环己酮的一锅三组分曼尼希型反应的催化活性，并获得了优异的收率。有趣的是，催化活性可以通过光辐照来调节。此外，反应完成后，产物可以很容易地通过萃取分离，水相在下一次运行中重新使用。最后，

• 2-Pyrrolidinecarboxylic Acid Ionic Liquid as a Highly Efficient Organocatalyst for the Asymmetric One-Pot Mannich Reaction

  日期：2010.1

  A novel one-pot three-component asymmetric Mannich reaction using [EMIm][Pro] (1) as a catalyst has been developed. By employing this new reaction system, a variety of optically active β-amino carbonyl compounds were synthesized in up to 99 % yield with up to >99 dr and >99 % ee. The reaction conditions have been optimized and the mechanism for the asymmetric induction is discussed.

  Direct asymmetric three-component Mannich reaction involving simple ketones (such as cyclohexanone, acetone, and acetophenone) as donors and catalyzing by silver tartaric acid-derived phosphate was realized to afford a series of optically active β-amino-ketone derivatives in high yields (up to 96%) and good-to-high enantioselectivities (up to 97%) with moderate-to-good diastereoselectivities. This

  A chiral Bronsted acid-catalyzed direct asymmetric Mannich reaction has been described. Various phosphoric acids, prepared from BINOL and H-8-BINOL derivatives, have been evaluated for catalyzing the direct Mannich reaction. In the presence of a truly catalytic amount of the phosphoric acid, anti-selective Mannich reactions of cyclic ketones with a wide scope of aldimines were obtained in high yields with excellent enantioselectivities (up to 98% ee) and high diastereomeric ratios (up to 98/2 dr). A one-pot Mannich reaction using aromatic ketones as donors proceeded smoothly to give beta-amino carbonyls with fairly good enantioselectivities.

  A lipase-catalyzed direct Mannich reaction of arylamines with aromatic aldehydes and ketones including cyclohexanone, butanone and 1-hydroxy-2-propanone was developed under EtOH/H2O system in a "one-pot" strategy. A series of experiments on the promiscuous activity of lipases were performed to optimize the biocatalytic process, and a wide scope of substrates was expanded with good yields.

  Acylase I from Aspergillus melleus (AMA) displayed catalytic promiscuity towards one-pot asymmetric Mannich reaction in acetonitrile for the first time. AMA showed favourable catalytic activity with good adaptability to different substrates. The activity and stereoselectivity of the enzyme could be improved by adjusting solvent, pH, water content, temperature, molar ratio of substrates and enzyme loading. The enantioselectivities up to 89% ee, diastereoselectivities up to 90:10 dr (syn/anti) and yields up to 82% were achieved. This work offered a novel case of enzyme catalytic promiscuity and a potential synthetic method for organic chemistry. (C) 2014 Elsevier B.V. All rights reserved.
