• Towards Sustainable Amino Acid Derived Organocatalysts for Asymmetric <i>syn</i> -Aldol Reactions

  side-processes responsible for the fast deactivation of primary amino acid derived organocatalysts in asymmetric aldol reactions are identified. A new ionic-liquid-supported (S)-valine-/(S)-α,α-diphenylserinol-derived catalyst (9) is designed on the basis of these results and exhibits much better recyclability in asymmetric syn-aldol reactions between hydroxyacetone and aldehydes. Furthermore, this catalyst

  鉴定了在不对称醛醇反应中导致伯氨基酸衍生的有机催化剂快速失活的不良副过程。基于这些结果设计了一种新的离子液体负载的 (S)-缬氨酸-/(S)-α,α-二苯基丝氨醇衍生催化剂 (9) 并在羟基丙酮之间的不对称合成羟醛反应中表现出更好的可回收性和醛类。此外，该催化剂似乎可用于通过不对称合成羟醛/内酯化级联反应立体选择性合成天然存在的 1(3H)-isobenzofuran-1-one 支架。

  The catalytic promiscuity of pepsin from porcine gastric mucous was observed in catalysis of the direct asymmetric aldol reactions of aromatic aldehydes with acetones, which were substituted by hydroxy-, dihydroxy-, methoxy- and benzyloxy- for the synthesis of diol compounds in acetonitrile. This biocatalysis was also applicable to the aldol reactions of cyclic or hetereocyclic ketones with aromatic

• Simple and inexpensive threonine-based organocatalysts for the highly diastereo- and enantioselective direct large-scale syn-aldol and anti-Mannich reactions of α-hydroxyacetone
  作者：Chuanlong Wu、Xiangkai Fu、Shi Li

  DOI：10.1016/j.tetasy.2011.06.022

  日期：2011.5

  Simple and inexpensive threonine-based organocatalysts that promote syn-aldol reactions and three-component asymmetric anti-Mannich reactions of alpha-hydroxyacetone achieving a respectable level of enantioselectivities are reported. The syn-aldol products could be obtained with up to a 99:1 syn/anti ratio and > 99% ee while the anti-Mannich products could be obtained with up to a 96:4 anti/syn ratio and > 99% ee. Catalyst 1c can be used efficiently on a large-scale with the enantioselectivities of the syn-aldol and anti-Mannich reactions being maintained at the same level, which offers a great possibility for application in industry.
