    摘要:
    比较开链仲,仲-1,2-二醇的双-(R)-或双-(S)-MPA酯衍生物的室温和低温1 H NMR光谱,可轻松确定其相对立体化学,有时甚至是绝对构型。如果二醇是抗性的,则其绝对构型可以直接从ΔδT1T2的符号推导出对于取代基R 1 / R 2,但如果二醇的相对立体化学是顺式,则其绝对构型的分配需要制备两种衍生物(双-(R)-和双-(S)-MPA酯) ,其室温的比较1 1 H NMR谱,并计算该Δδ的RS次甲基Hα(R 1)和Hα(R 2)和R 1 / R 2质子的符号。这些相关性的可靠性通过用作模型化合物的已知绝对构型的17种二醇进行了验证。

    anti-Selective aldol reactions of chiral alcohol substituted γ-benzyloxyl vinylogous urethanes and the synthesis of 3-benzyloxyl-4-hydroxylalkan-2-ones
    摘要:
    The anti-selective aldol reaction of chiral alcohol-substituted gamma-benzyloxy vinylogous urethanes is described. The use of (1S,2R,4R)-1-(hydroxydiphenylmethyl)-7,7-dimethylbicyclo[2,2,1]-heptan-2-ol as a chiral auxiliary in the aldol reaction of a vinylogous urethane enolate was found to provide anti-products in good yields with moderate to excellent enantioselectivities. The major anti-vinylogous urethane lactones were transformed into 3-benzyloxyl-4-hydroxylalkan-2-ones in good yields. (C) 2017 Elsevier Ltd. All rights reserved.

    water-compatible amino-acid-based catalysts was explored in the development of diastereo- and enantioselective direct aldol reactions of a broad range of substrates. Chiral C2-symmetrical proline- and valine-based amides and their ZnII complexes were designed for use as efficient and flexible chiral catalysts for enantioselective aldol reactions in water, on water, and in the presence of water. The presence of
    在本文中,在开发多种底物的非对映和对映选择性直接羟醛反应中,探索了与水相容的氨基酸基催化剂的实用性。手性C 2对称的脯氨酸和缬氨酸基酰胺及其Zn II配合物被设计用作有效和灵活的手性催化剂,用于水,水和水存在下的对映选择性醛醇缩合反应。5 mol%的脯氨酰胺基催化剂的存在使未改性的酮与各种醛之间发生不对称的分子间羟醛反应,从而得到抗氧化剂。具有优异对映选择性的产品。我们还证明了对水具有较高亲和力的要求更高的底物(如丙酮和甲醛)的醛醇缩合反应。新设计的基于丝氨酸的有机催化剂促进了羟丙酮的醛醇缩合反应,生成了顺式二醇。对于提出的催化体系,无溶剂的条件也是可以接受的,这使得从绿色化学的角度出发,详细的方法变得很有趣。

    The aldol reaction of hydroxyacetone with different aldehydes using immobilized proline on a mesoporous support, assisted by heat and microwaves, has been explored. It was found that heterogenized L-proline on MCM-41 catalyzed aldol reactions in both hydrophilic and hydrophobic solvents, and provided stereoselectivities in some cases complementary to the homogeneous catalyst. The heterogeneous catalysts
