    Hydroboration–azide alkylation as efficient tandem reactions for the synthesis of chiral non racemic substituted pyrrolidines
    摘要:
    The synthesis of chiral non racemic substituted pyrrolidines from homoallylic alcohols is presented. These precursors are readily converted via the azides to the corresponding pyrrolidines using hydroboration-cycloalkylation tandem reactions as key steps. (C) 1998 Elsevier Science S.A.

  • Enantio- and Diastereoselective Synthesis of Hydroxy Bis(boronates) via Cu-Catalyzed Tandem Borylation/1,2-Addition
    作者:Jacob C. Green、Matthew V. Joannou、Stephanie A. Murray、Joseph M. Zanghi、Simon J. Meek
    DOI:10.1021/acscatal.7b01123
    日期:2017.7.7
    Catalytic enantioselective synthesis of 1-hydroxy-2,3-bisboronate esters through multicomponent borylation/1,2-addition is reported. Catalyst and substrates are readily available, form both a C–B and C–C bond, and generate up to three contiguous stereocenters. The reaction is tolerant of aryl, vinyl, and alkyl aldehydes and ketones in up to 95% yield, >20:1 dr, and 99:1 er. Intramolecular additions
    报道了通过多组分硼化/1,2-加成催化对映选择性合成 1-羟基-2,3-二硼酸酯。催化剂和底物很容易获得,形成 C-B 和 C-C 键,并生成最多三个连续的立体中心。该反应可耐受芳基、乙烯基和烷基醛和酮,产率高达 95%,dr 大于 20:1,er 大于 99:1。醛和酮的分子内加成导致立体发散过程。羟基双(硼酸酯)酯产品适合进行位点选择性化学加工。
  • Straightforward chemoselective access to unsymmetrical dithioacetals through a thiosulfonate homologation-nucleophilic substitution sequence

    presented for the preparation of rare unsymmetrical dithioacetals. The judicious selection of thiosulfonates as convenient sulfur electrophilic sources upon the homologation event conducted on an intermediate α-halothioether guarantees the release of the non-reactive sulfonate group, thus enabling the subsequent nucleophilic displacement with an external added thiol [(hetero)aromatic and/or aliphatic]
    介绍了一种连续的C1同源性亲核取代策略,用于制备稀有的不对称二硫缩醛。明智地选择硫代磺酸盐作为方便的亲电子硫源(在中间体α-卤代硫醚上进行的同源化事件后)可确保释放非反应性磺酸盐基团,从而使随后的亲核置换反应可在外部添加硫醇[(杂)芳族化合物和/或脂肪族]。在广泛的研究范围内得出了一致的高收率和出色的化学防治效果,从而证明了直接技术制备这些独特且可操作的材料的多功能性。
  • Cascade Reactions: Catalytic Synthesis of Functionalized 1,3-Dihydroisobenzofuran and Tetrahydrofuran Derivatives by Sequential Nucleophilic Ring Opening-Heterocyclization- Oxidative Carbonylation of Alkynyloxiranes
    作者:Nicola Della Ca'、Fabio Campanini、Bartolo Gabriele、Giuseppe Salerno、Chiara Massera、Mirco Costa

    日期:2009.10
    Differently substituted alkynyloxiranes were efficiently converted into functionalized 1,3-dihydroisobenzofurans and tetrahydrofuran derivatives in fair to good yields by a new cascade reaction, consisting of a sequential nucleophilic ring opening–heterocyclization–oxidative carbonylation process. Reactions were carried out at 80–100 °C and under a 3:1 mixture of carbon monoxide and air (total pressure=32–42 atm
    通过新的级联反应,包括顺序的亲核开环-杂环化-氧化羰基化过程,可以将不同取代的炔基肟基化合物有效地高效转化为官能化的1,3-二氢异苯并呋喃和四氢呋喃衍生物。反应在甲醇或乙腈/甲醇混合物中,在催化量的钯存在下,于80–100°C和一氧化碳与空气的3:1混合物(25°C下总压力= 32–42 atm)下进行二碘化物和过量的碘化钾。通过对环氧乙烷环的受阻较小的碳的区域选择性攻击而开始级联过程的亲核物质可以是甲醇本身或碘化物阴离子。

    Nickel-catalyzed 1,2-carboboration of alkenes is emerging as a useful method for chemical synthesis. Prior studies have been limited to only the incorporation of aryl groups. In this manuscript, a method for the 1,2-benzylboration of unactivated alkenes is presented. The reaction combines readily available alkenes, diboron reagents and benzylchlorides to generate synthetically versatile products with

Further functional group transformations of the tertiary boronic esters were demonstrated (conversion to quaternary centers, C-tertiary amines) together with application of the methodology to the synthesis of the simplest unbranched hydrocarbon
    据报道,简单的仲 2,4,6-三异丙基苯甲酸酯 (TIB 酯) 和仲二烷基 N,N-二异丙基氨基甲酸酯可抵抗强碱的去质子化。我们发现 sBuLi(1.6 当量)和 TMEDA(6 当量)在 CPME 中在 -60 °C 下的组合能够使未活化的仲二烷基 TIB 酯去质子化,但不能使氨基甲酸酯去质子化。这些碳负离子与一系列新戊基硼酸酯反应,在 1,2-金属酸盐重排和氧化后,以高产率和普遍更高的效率得到一系列叔醇。证明了叔硼酸酯的进一步官能团转化(转化为季中心,C-叔胺)以及该方法应用于合成最简单的带有季中心的无支链烃,
