  • Mechanistic Studies on the Organocatalytic α‐Chlorination of Aldehydes: The Role and Nature of Off‐Cycle Intermediates
    作者:Sebastian Ponath、Martina Menger、Lydia Grothues、Manuela Weber、Dieter Lentz、Carsten Strohmann、Mathias Christmann
    DOI:10.1002/anie.201806261
    日期:2018.9.3
    Herein we report the isolation and characterization of aminal intermediates in the organocatalytic α‐chlorination of aldehydes. These species are stable covalent ternary adducts of the substrate, the catalyst and the chlorinating reagent. NMR‐assisted kinetic studies and isotopic labeling experiments with the isolated intermediate did not support its involvement in downstream stereoselective processes
    在这里,我们报告了醛的有机催化 α-氯化中缩醛胺中间体的分离和表征。这些物质是底物、催化剂和氯化试剂的稳定共价三元加合物。NMR 辅助动力学研究和分离中间体的同位素标记实验不支持其参与 Blackmond 提出的下游立体选择性过程。通过调整氯化试剂的反应性,我们能够抑制限速非循环中间体的积累。因此,开发了一种高效且高度对映选择性的催化体系,具有广泛的官能团耐受性。
  • Enantioselective nickel-catalyzed <i>anti</i>-arylmetallative cyclizations onto acyclic electron-deficient alkenes

  • Cation-stabilizing auxiliaries in polyene cyclizations. 5. The fluorine atom as a cation-stabilizing auxiliary in biomimetic polyene cyclizations. 2. Asymmetric synthesis of a steroid

    日期:1993.1
    The use of the fluorine atom an a cation-stabilizing (C-S) auxiliary for enhancing polyene cyclization has been improved in synthetic effectiveness by the demonstration that an acetal 5 can be converted to a racemic fluorocycle, bearing the natural backbone configuration of the steroids

  • Macrolides from the scent glands of the tropical butterflies Heliconius cydno and Heliconius pachinus
    作者:Stefan Schulz、Selma Yildizhan、Katja Stritzke、Catalina Estrada、Lawrence E. Gilbert
    DOI:10.1039/b710284d
    日期:——
    The four major components present in scent gland extracts of the male Costa Rica longwing butterflies Heliconius cydno and Heliconius pachinus were identified as 12- and 14-membered macrolides containing a C18-carbon skeleton. By use of micro-reactions and spectrometric examinations, structural proposals were made and subsequently proven by synthesis, using ring-closing-metathesis as the key steps. These macrolides, (9Z,11E,13S)-octadeca-9,11-dien-13-olide (5, S-coriolide), (9Z,11E,13S,15Z)-octadeca-9,11,15-trien-13-olide (6), (9Z,13S)-octadec-9-en-13-olide (13), and (9Z,11S)-octadec-9-en-11-olide (25), are biosynthetically obviously derived from oleic, linoleic, and linolenic acids. Their absolute configurations were determined by gas chromatographic investigations on chiral phases, showing all to possess (S)-configuration.
    哥斯达黎加长翼蝴蝶(Heliconius cydno 和 Heliconius pachinus)雄性蜕皮腺萃取物中发现的四种主要成分被确定为含有C18碳骨架的12-和14-membered大环内酯。通过微反应和光谱检测,提出了结构方案,并通过合成验证,这一过程以环闭合重排为关键步骤。这些大环内酯包括(9Z,11E,13S)-十八烯-9,11-二烯-13-内酯(5, S-柯里内酯)、(9Z,11E,13S,15Z)-十八烯-9,11,15-三烯-13-内酯(6)、(9Z,13S)-十八烯-9-烯-13-内酯(13)和(9Z,11S)-十八烯-9-烯-11-内酯(25),这些化合物在生物合成上显然源自油酸、亚油酸和亚麻酸。它们的绝对构型通过对手性相的气相色谱分析确定,显示全部为(S)-构型。
