  A series of primary-tertiary diamine catalysts were designed and synthesized from primary natural amino acids. Application of these new chiral catalysts in direct aldol reactions of α-hydroxyketones showed very good catalytic activity (up to 97% yield) and high syn selectivity (up to syn/ anti = 30:1, 99% ee).

  Seven primary amine organocatalysts 1a−g were readily prepared from natural primary amino acids via two steps and then were used to catalyze the direct asymmetric aldol reaction, but they showed very poor enantioselectivities and activities. As an effective cocatalyst, 2,4-dinitrophenol (DNP) dramatically elevated the activities and enantioselectivities of these very inefficient primary amine organocatalysts

  可以通过两步从天然伯氨基酸容易地制备出7种伯胺有机催化剂1a - g，然后将其用于催化直接不对称羟醛反应，但它们的对映选择性和活性非常差。作为一种有效的助催化剂，2,4-二硝基苯酚（DNP）大大提高了这些非常低效的伯胺有机催化剂的活性和对映选择性。与从头开发催化剂相比，通过选择和使用最佳助催化剂对非常低效的有机催化剂进行这种补救的过程特别具有成本效益且对环境有利。由1f组成的最高效的有机催化系统DNP表现出高的对映选择性和良好的非对映选择性，具有广谱的七种酮。线性酮和环戊酮主要合成产物，而环己酮主要产生反产物。

  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

  在催化芳香族醛与丙酮直接不对称醛醇缩合反应的催化过程中，观察到了胃蛋白酶对胃蛋白酶的混杂作用，丙酮醛被羟基，二羟基，甲氧基和苄氧基所取代，从而在乙腈中合成二醇化合物。该生物催化也适用于环状或杂环酮与芳族醛的醛醇缩合反应。获得了高达87％的产率，高达> 99/1 dr的非对映选择性和高达75％ee的对映选择性。

  Inorganic ammonium salts catalyze the direct aldol reaction between unmodified ketones and aldehydes to furnish the corresponding β-hydroxy ketones in aqueous media. The reactions are highly chemoselective and operationally simple.

  Chiral ionic liquids containing (S)- or (R)-threonine amide and alpha,alpha-(S)-diphenylvalinol units were synthesized In the presence of the (S)-threonine-derived catalyst reactions between ketones with secondary carbon atom(s) at the alpha-position with respect to the carbonyl group and aromatic (heteroaromatic) aldehydes afforded the corresponding syn-aldols in high yields (up to 99%) and with high diastereo-(syn/anti up to 97:3) and enantioselectivity (up to 99% ee), which was maintained over three reaction cycles.
