  Utilization of biocatalytic promiscuity for direct Mannich reaction

  摘要：

  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.

• Isosteviol-amino Acid Conjugates as Highly Efficient Organocatalysts for the Asymmetric One-pot Three-component Mannich Reactions

  日期：2011.7

  Isosteviol‐amino acid conjugates were synthesized and used as chiral catalysts for the asymmetric three‐component Mannich reaction with hydroxyacetone as donor molecule. Good yields (up to 98%) and excellent stereoselectivities (up to 97:3 dr and 99% ee) were achieved in a short reaction time. In addition, syn‐ or anti‐configurations of α‐hydroxy‐β‐amino carbonyl compounds were obtained as main products

• Continuous Flow Enantioselective Three-Component <i>anti</i>-Mannich Reactions Catalyzed by a Polymer-Supported Threonine Derivative

  A series of primary amino acid-derived polystyrene-supported organocatalysts was tested in antiselective Mannidi reactions. The polystyrene-immobilized threonine derivative showed the best performance in threecomponent (hydroxyacetone, anilines, and aldehydes) Mannich reactions to provide anti-beta-amino-alpha-hydroxycarbonyl compounds (11 examples; up to 95% ee), and its use could be extended to dihydroxyacetone and protected hydroxyace-tones (7 examples; up to 90% ee). The high activity depicted by the catalyst has allowed its implementation in continuous flow. Under this operation mode, the supported threonine catalyst produces anti-Mannich adducts with generally higher diastereo- and enantioselectivity than in batch. A family of five different enantioenriched anti-Mannich adducts has been sequentially prepared in flow by passing different combinations of anilines and aromatic aldehydes over the same sample of catalyst. This confirms the suitability of this methodology for the rapid access to small libraries of enantioenriched compounds.
