  • Indium(III)-Catalyzed Knoevenagel Condensation of Aldehydes and Activated Methylenes Using Acetic Anhydride as a Promoter
    作者:Yohei Ogiwara、Keita Takahashi、Takefumi Kitazawa、Norio Sakai
    DOI:10.1021/acs.joc.5b00011
    日期:2015.3.20
    amount of InCl3 and acetic anhydride remarkably promotes the Knoevenagel condensation of a variety of aldehydes and activated methylene compounds. This catalytic system accommodates aromatic aldehydes containing a variety of electron-donating and -withdrawing groups, heteroaromatic aldehydes, conjugate aldehydes, and aliphatic aldehydes. Central to successfully driving the condensation series is the formation
    催化量的InCl 3和乙酸酐的组合显着促进了各种醛和活化的亚甲基化合物的Knoevenagel缩合。该催化体系可容纳含有各种供电子和吸电子基团的芳族醛,杂芳族醛,共轭醛和脂族醛。成功驱动缩合反应系列的关键是双乙酸双酯中间体的形成,该中间体是在铟催化剂的帮助下由醛和酸酐就地生成的。
  • Synthesis of polysubstituted 1,3-cyclohexadienes from ?-branched ?,?-alkenals and monoesters of ylidenemalonic acids
    作者:A. G. Nigmatov、I. N. Kornilova、E. P. Serebryakov
    DOI:10.1007/bf01433750
    日期:1996.1
    configurations of which were determined by means of1H NMR spectroscopy. In some cases the formation of cyclic dienes is impeded by the competing process of decarboxylation of acidic ylidenemalonates. The derivatives of 4,6-diphenyl-1,3-cyclohexadienecarboxylic acid were shown to be convenient precursors for the preparation ofmeta-terphenyls.
    摘要 3-甲基-和3-苯基-2-丁烯醛与亚烷基-、亚链烯基-和芳基亚甲基丙二酸的单酯在哌啶作为催化剂的存在下反应得到4,6-二取代的1,3-环己二烯羧酸在23 –96% 的产量。在相同条件下,亚环己基乙醛与异戊二烯-和亚苄基丙二酸的单酯反应,得到 1,5,6,7,8,8a 1-取代烷基的 1,8a-反式和 1,8a-顺式异构体的混合物-六氢化萘-2-羧酸盐,其比例和构型通过 1 H NMR光谱测定。在某些情况下,环状二烯的形成受到酸性亚亚基丙二酸酯脱羧的竞争过程的阻碍。4,6-二苯基-1的衍生物,
  • Construction of contiguous chiral tertiary carbon centers by enantioselective Michael reaction of ketone lithium enolates using a chiral amine ligand
    作者:Kōsuke Yasuda、Mitsuru Shindo、Kenji Koga
    DOI:10.1016/s0040-4039(97)00695-3
    日期:1997.5
    The diastereo- and enantioselective Michael reaction of ketone lithium enolates using a chiral amine ligand (1) was examined. Michael adducts (4) were obtained in excellent chemical yields (95∼99%) with high stereoselectivities (; ee of anti-4: 81∼99%) by the reaction between alkyl phenyl ketones (2) and Michael acceptors (3) having an alkylidene group.
    使用手性胺配体(1)研究了酮烯酸锂的非对映和对映选择性Michael反应。通过烷基苯基酮(2)与迈克尔受体(3)之间的反应,可以以优异的化学收率(95〜99%)获得具有高立体选择性的Michael加合物(4的ee:81〜99 %)。亚烷基。
  • Enantioselective Lewis Acid Catalyzed Michael Reactions of Alkylidene Malonates. Catalysis by <i>C</i><sub>2</sub>-Symmetric Bis(oxazoline) Copper(II) Complexes in the Synthesis of Chiral, Differentiated Glutarate Esters
    作者:David A. Evans、Tomislav Rovis、Marisa C. Kozlowski、C. Wade Downey、Jason S. Tedrow
    DOI:10.1021/ja002246+
    日期:2000.9.1
    C2-symmetric bis(oxazoline)−Cu(II) complexes 1 catalyze the Mukaiyama Michael reaction of alkylidene malonates and enolsilanes. The use of hexafluoro-2-propanol is essential to induce catalyst turnover. High enantioselectivities are exhibited by bulky alkylidene malonate β-substituents using catalyst 1a. The glutarate ester products are readily decarboxylated to provide chiral 1,5-dicarbonyl synthons
    C2-对称双(恶唑啉)-Cu(II)配合物1催化亚烷基丙二酸酯和烯醇硅烷的Mukaiyama Michael反应。六氟-2-丙醇的使用对于诱导催化剂周转至关重要。使用催化剂 1a 的庞大的亚烷基丙二酸酯 β-取代基表现出高对映选择性。戊二酸酯产物很容易脱羧以提供手性 1,5-二羰基合成子。底物-催化剂复合物的晶体学表征提供了对与这些催化剂的结合事件的深入了解,并为观察到的面部选择性提供了基本原理。
  • A One-Pot Preparation of 1,3-Disubstituted Azetidines
    作者:Michael C. Hillier、Cheng-yi Chen
    DOI:10.1021/jo061147x
    日期:2006.9.1
    A straightforward synthesis of 1,3-disubstituted azetidines has been accomplished via the alkylation of a primary amine with the bis-triflate of a 2-substituted-1,3-propanediol species. This transformation is carried out in one reaction vessel, and elimination of the alkylating reagent is generally not a major byproduct. The scope of this methodology has been investigated using a variety 2-substituted-1
    通过伯胺与2-取代的1,3-丙二醇的双三氟甲磺酸酯的烷基化,已经完成了1,3-二取代的氮杂环丁烷的直接合成。该转化是在一个反应​​容器中进行的,烷基化试剂的消除通常不是主要的副产物。已经使用各种2-取代的1,3-丙二醇和胺亲核试剂研究了该方法的范围。
