    降冰片基α-二酮非对映选择性合成螺环二氢呋喃和1-Oxaspiro[4.5]decan-6-one衍生物
    摘要:
    据报道,非对映选择性锌介导的非烯醇化降冰片基 α-二酮的炔丙基化和有效的 AgI 催化的 α-酮基高炔丙基醇与末端炔烃的环异构化导致螺环二氢呋喃。获得的二氢呋喃进行氢化以几乎定量的产率(98-99%)提供螺四氢呋喃衍生物。最终,制备的 α-螺四氢呋喃降冰片基单酮用作酸介导的 Grob 型断裂反应的前体,并通过对甲苯磺酸处理转化为 1-oxaspiro[4.5]decan-6-one 衍生物。

    Highly efficient and recyclable ruthenium-based supported catalysts
    摘要:
    A highly efficient, recyclable layered double hydroxide (LDH)-supported ruthenium catalyst system (Ru-LDH) was developed for the facile transformation of 1,2-dihaloalkene moieties in tetrahalonorbornyl derivatives to the corresponding alpha-diketones. The efficiency of other supports such as LDH containing ruthenium(III) in a brucite layer (Ru-Mg-Al), commercial MgO (Ru-MgO), and montmorillonite K-10 (Ru-mont) was evaluated. Our results demonstrate that Ru-LDH and Ru-MgO are equally efficient, and the best turnover number (TON) reached was 5389. For NalO(4) as the co-oxidant, MeCN-H2O was the best solvent, whereas 1,2-dichloroethane/MeCN in a ratio of 5:1 gave superior results for NaOCl (household bleach). (c) 2005 Elsevier Inc.

  • Indium-Mediated Regio- and Diastereoselective Reduction of Norbornylα-Diketones
    作者:Faiz Ahmed Khan、Jyotirmayee Dash、Ch. Sudheer

    日期:2004.5.17
    bicyclic alpha-diketones into synthetically useful acyloins mediated by indium metal is described. The reduction is highly diastereoselective, leading exclusively to endo-acyloins (endo-hydroxyl groups) in excellent yields, and tolerates a variety of sensitive substituents, such as acetate, ester, and bridgehead halogens. The regioselectivity in the reductions of monosubstituted alpha-diketones varied
    描述了一种新的,有效的,区域性的以及非对映选择性的将非可烯化的双环α-二酮转化为属介导的合成有用的酰基辅酶的方法。该还原是高度非对映选择性的,仅以优异的产率仅产生内酰基-糖苷(内羟基),并耐受各种敏感的取代基,例如乙酸盐,酯和桥头卤素。对于两种可能的异构醇,在单取代的α-二酮还原中的区域选择性从70:30到100:0不等。该方法扩展到了高度官能化的环戊烷甲醛的合成,这是有机合成中的潜在组成部分,通过在MeOH / PhH中用Pb(OAc)4处理酰基转移酶来裂解酰基转移酶。

    [reaction: see text] Alpha-diketones are efficiently reduced with indium metal in methanol-water in the presence of NH(4)Cl, LiCl, or NaCl to give regio- and diastereoselectively the corresponding acyloins in good to excellent yield. The cleavage of the acyloins under Pb(OAc)(4)/MeOH-PhH condition provides a convenient and regioselective access to highly functionalized cyclopentane carboxaldehydes

  • Diastereoselection During Allylindium Addition to Norbornylα-Diketones
    作者:Faiz Ahmed Khan、Jyotirmayee Dash
    DOI:10.1002/ejoc.200400044
    日期:2004.6
    We report a highly regio- and diastereoselective allylindium addition to norbornyl α-diketones that leads to acyloins. The diastereoselection in the case of monosubstituted derivatives greatly depends on the nature of the 5-endo substituents. Non-chelating groups direct the addition from the sterically less congested exo-face, diagonal to the substituent, while chelating substituents, such as an alkoxy
    我们报告了一种高度区域选择性和非对映选择性的烯丙基添加到降冰片基 α-二酮中,导致 acyloins。在单取代衍生物的情况下,非对映选择很大程度上取决于 5-内取代基的性质。非螯合基团引导从空间上不太拥挤的外表面加成,与取代基对角,而螯合取代基,如烷氧基或乙酰氧基单元,诱导选择性的完全逆转。与降冰片基骨架直接连接的氧原子的存在对于引发螯合效应至关重要,因为乙酰氧基甲基 (-CH2OAc) 基团表现出正常行为并充当非螯合基团。注意到明显无害的外-Me 取代基的显着影响(逆转)。(© Wiley-VCH Verlag GmbH & Co.
