  立体和电子可调和双功能有机催化剂：环酮与醛的不对称羟醛反应的设计和应用

  摘要：

  在杂环酮的直接醛醇缩合反应中，已经开发并评估了可立体和电子可调的双功能有机催化剂。具有不同取代基的催化剂对类似的底物显示出不同的催化效率，表明微调两个NH基团中氢键强度的重要性。反应全部以良好至高收率进行，并且具有从90％至> 99％ee的优异对映选择性。在大多数情况下，抗羟醛加合物的非对映选择性高，为96/4至99/1。

  direct asymmetric stoichiometric aldol reaction on water by using variable amounts of water. These threonine-based organocatalyst were simple, inexpensive, highly active and could be synthesized on a large-scale. Among them, the threonine-based organocatalyst 1a is applicable to the stoichiometric reactions of a wide range of aromatic and heteroaromatic aldehydes with ketones, with the aldol products

  通过使用可变量的水，筛选了九种O-酰化苏氨酸，其负载量为0.5–5 mol％，可用于在水中直接不对称化学计量的羟醛直接反应。这些基于苏氨酸的有机催化剂简单，廉价，活性高，可以大规模合成。其中，基于苏氨酸的有机催化剂1a适用于多种芳香族和杂芳香族醛与酮的化学计量反应，所制得的醛醇产物的反/合成比高达99：1 ，ee大于99％。苏氨酸基有机催化剂1a可以容易地回收和再利用，并且在六个循环后仅观察到对映选择性的轻微降低。该新的基于苏氨酸的有机催化剂1a可以有效地用于大规模反应，同时将对映选择性保持在相同水平，这为工业应用提供了很大的可能性。

  The new promiscuous activity of lipase from porcine pancreas, type II (PPL II), has been observed to catalyze the direct asymmetric aldol reaction of heterocyclic ketones with aromatic aldehydes. PPL II showed favorable catalytic activity and had a good adaptability to different substrates in the reaction. The enantioselectivities of up to 87% ee and diastereoselectivities of up to 83:17 (anti/syn) were achieved. It is interesting that PPL II possesses the function of aldolase in organic solvents.

  Novel (S)-prolinamides with stereoisomeric 2-hydroxy-3-aminopinane units have been synthesized. In the presence of (1R,2R,3S,5R)-2-hydroxy-3-[(S)-prolinamido]pinane (5 mol %) cyclic ketones reacted with (hetero-)aromatic aldehydes in aqueous media to afford chiral aldols in high yields. The reaction had moderate to high diastereo- (dr up to 91/9) and enantioselectivities (up to 83% ee). (C) 2011 Elsevier Ltd. All rights reserved.
