  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。

  are amino acids and cinchona alkaloid derivatives, leads to the direct formation of the desired organocatalysts without any synthesis. These modularly designed organocatalysts (MDOs) may be used for catalyzed asymmetric aldol reaction. Depending on structure of the aldehyde substrates, the corresponding aldol products may be obtained in mediocre to excellent ee values (up to 92% ee) with moderate diastereoselectivities

  日期：2007.11

  (S)-NOBIN-L-prolinamide was employed as organocatalyst in the direct aldol reactions of different ketones and aromatic aldehydes using dioxane as solvent and in the presence of water as additive. Acetone led to the aldol products in up to 93% ee, while cyclic ketones furnished the anti-aldols in moderate to high yield, excellent diastereoselectivity (up to > 99/< 1 anti/syn ratio) and high ee (up to 95%).
