  A Useful Synthetic Equivalent of a Hydroxyacetone Enolate

  摘要：

  Indium promoted allyiation of carbonyl compounds with 4-(bromomethyl)-1,3-dioxol-2-one diastereoselectively affords and-alpha,beta-dihydroxyketones, protected as enol carbonates. These initial products can be deprotected to free dihydroxyketones or transformed under mild conditions Into the corresponding cyclic carbonates, which constitutes a useful approach to hydroxyacetone aldois.

  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

  novel class of chiral diamine organocatalysts based on natural primary amino acids that efficiently catalyze syn-selective aldol reactions of challenging linear ketones, such as 2-butanone, and aromatic aldehydes. In the presence of trifluoroacetic acid (TFA) as Brønsted acid and 2,4-dinitrophenol (DNP) as co-catalyst, syn-aldol products have been obtained with excellent enantioselectivities of up to> 99%

  anti-1,2-amino alcohols and syn-1,2-diols through direct asymmetric Mannich, Mannich-type, and aldol reactions involving unmodified α-hydroxyketones in reactions catalyzed by primary amine-containing amino acids. These reactions exploit (Z)-enamines of α-hydroxyketones in their bond-forming transition states. This study compliments and extends our bioorganic approach to asymmetric synthesis in these two

  手性 1,2-氨基醇和 1,2-二醇是在大量天然和生物活性分子中发现的常见结构基序。已经报道了使用基于金属的策略有效对映选择性合成含有顺-或反-1,2-氨基醇和1,2-二醇的酮。然而，迄今为止，涉及有机催化的方法仅限于合成 1,2-氨基醇和反 1,2-二醇。在此，我们公开了通过直接不对称曼尼希、曼尼希型和羟醛反应（涉及未修饰的 α-羟基酮在伯胺催化的反应中）制备高度对映体富集的抗 1,2-氨基醇和合成 1,2-二醇的简单有效途径-含氨基酸。这些反应利用处于成键过渡态的 α-羟基酮的 (Z)-烯胺。这项研究补充并扩展了我们在这两种多功能合成子类中进行不对称合成的生物有机方法。值得注意的是，这些反应是实用的，耐受湿溶剂，并且...
