  • HYDROGENATION OF ESTERS OR CARBONYL GROUPS WITH TETRADENTATE AMINO/IMINO-THIOETHER BASED RUTHENIUM COMPLEXES

    The present invention relates to the field of catalytic hydrogenation and, more particularly, to the use of specific ruthenium catalysts, or pre-catalysts, in hydrogenation processes for the reduction of ketones and/or aldehydes into the corresponding alcohol respectively. Said catalysts are ruthenium complexes comprising a tetradentate ligand (L4) coordinating the ruthenium with: two nitrogen atoms, each in the form of a primary or secondary amine (i.e. a NH 2 or NH group) or N-alkyl imine functional groups (i.e. a C═N group), and two sulfur atoms, each in the form of thioether functional groups.
    本发明涉及催化加氢领域,更具体地涉及在氢化过程中使用特定的催化剂或前驱体,用于将酮和/或醛还原为相应的醇。所述催化剂是包括一个四齿配体(L4)与配位的络合物,其中:两个氮原子,每个以一种主要或次要胺(即NH2或NH基团)或N-烷基亚胺功能基团(即C═N基团)的形式存在,以及两个原子,每个以醚功能基团的形式存在。
  • Enantioselective reduction of ketones with a silane agent/metal compound/chiral ligand system

    A process for the enantioselective reduction of prochiral ketones to chiral alcohols by (a) the reaction of a prochiral ketone with a silane agent, which is present in a stoichiometric quantity, in the presence of a catalyst derived from a Zn, Co or Cd precursor compound and from a chiral amine, imine, alcohol or amino alcohol ligand; (b) the hydrolysis of the siloxane obtained using an appropriate agent; and (c) the separation and purification of the optically active alcohol formed. Polymethylhydrosiloxane (PMHS) is a preferred silane agent, zinc is a preferred metal, and the precursor compound is produced by reacting a salt or complex of the respective metal with the reducing agent. In another embodiment, an appropriate salt of the chosen metal is used directly in the reaction with the chiral ligand to produce the catalytic form after reaction with the ligand. The process enables high enantiomeric excesses (ee) to be obtained in chiral alcohols.
    一种关于手性选择性还原的方法,将非手性羰基酮还原为手性醇,方法包括:(a) 在催化剂的作用下,将非手性羰基酮与硅烷剂反应,硅烷剂的用量与非手性羰基酮的摩尔比相等,催化剂来源于前驱化合物和手性胺、亚胺、醇或基醇配体;(b) 使用适当试剂解得到硅氧烷;(c) 分离和纯化生成的光学活性醇。聚甲基氢硅氧烷(PMHS)是首选的硅烷剂,是首选属,前驱化合物通过将相应属的盐或络合物与还原剂反应而产生。在另一种实施方案中,选择属的适当盐直接与手性配体反应,生成催化形式。该方法使得手性醇中可以获得高对映体过量(ee)。

    Highly regioselective reductions of α,β-unsaturated ketones to the corresponding allylic alcohols were performed in essentially quantitative yields in aqueous media containing either glycosidic surfactants or amphiphilic carbohydrates. Reductions of cyclohexanones and cyclohexenones lead under the same conditions, stereoselectively to reduced compounds bearing an equatorial alcohol function. Hydrophobic

  • A New Variant of the Claisen Rearrangement from Malonate-Derived Allylic Trimethylsilyl Ketene Acetals: Efficient, Highly Enantio- and Diastereoselective Syntheses of (+)-Methyl Dihydroepijasmonate and (+)-Methyl Epijasmonate
    作者:Charles Fehr、José Galindo
    DOI:10.1002/(sici)1521-3773(20000204)39:3<569::aid-anie569>3.0.co;2-8
    日期:2000.2.4
    Complete chirality transfer occurs in the smooth Claisen rearrangement of the trimethylsilyl (TMS) ketene acetals, which were prepared from allylic malonates (R)-1 (R=pentyl, 2-(Z)-pentenyl). These are in turn accessible by enantioselective reduction/esterification or by enzymatic kinetic resolution. The cis configuration in (+)-3 was achieved by highly syn-selective epoxidation of (+)-2, followed
    完全手性转移发生在由烯丙基丙二酸酯(R)-1(R =戊基,2-(Z)-戊烯基)制得的三甲基甲硅烷基(TMS)乙烯酮缩醛的平滑克莱森重排中。这些反过来可通过对映选择性还原/酯化或酶动力学拆分来获得。(+)-3中的顺式构型是通过(+)-2的高度同位选择性环氧化实现的,然后进行表面上的1,2-H迁移。
