    摘要:
    A ruthenium-mediated intramolecular [3 + 2] cycloaddition of bis-1,3-dienes to give bicyclic products, which is a novel non-metathetic behavior of Grubbs catalyst, is reported. The formation of a ruthenium-olefin complex is proposed to be a key step for the success of the reaction. (C) 2012 Elsevier B.V. All rights reserved.

  • Synthesis of the C1–C17 Segment of Bafilomycin N
    作者:Seijiro Hosokawa、Haruka Sato
    DOI:10.1055/s-0037-1611727
    日期:2019.3

    The C1–C17 segment of bafilomycin N has been synthesized. The C1–C11 segment was synthesized by the anti-selective vinylogous Mukaiyama aldol reaction with a chiral vinylketene silyl N,O-acetal and the Horner–Wadsworth–Emmons reaction, whereas C12–C17 was constructed by the syn-selective vinylogous Mukaiyama aldol reaction and the Jung’s semipinacol rearrangement. Those segments were connected by the Stille coupling to afford the C1–C17 segment.

    巴非洛霉素N的C1-C17片段已经合成。C1-C11片段通过反选择性的烯基Mukaiyama醛缩反应,使用手性乙烯酮N,O-缩醛和Horner-Wadsworth-Emmons反应合成,而C12-C17则通过同选择性的烯基Mukaiyama醛缩反应和Jung的半蒲托重排反应构建。这些片段通过Stille偶联连接以得到C1-C17片段。
  • Research on Au(I)-catalyzed ene-yne cycloisomerization for construction of quassinoid scaffold
    作者:Yuta Oki、Masahisa Nakada
    DOI:10.1016/j.tetlet.2018.01.069
    日期:2018.3
    Compounds that undergo Au(I)-catalyzed cycloisomerizations affording tetracyclic products that can be converted into compounds with the skeleton of bruceantin are described. The Au(I)-catalyzed cycloisomerizations reported herein are hindered by a 1,3-diaxial interaction between the substituent and the methyl group in the transition state. The use of small substituents was found to increase the yield
    描述了经历Au(I)催化的环异构化的化合物,其提供了可以转化为具有布鲁斯汀骨架的四环产物。本文报道的Au(I)催化的环异构化受到过渡态中取代基和甲基之间的1,3-双轴相互作用的阻碍。发现使用小的取代基可增加所需产物的产率,而底物与大的取代基的反应提供了不希望的结构异构体。
  • Total Synthesis of Bafilomycin A<sub>1</sub>
    作者:Florian Kleinbeck、Erick M. Carreira
    DOI:10.1002/anie.200804645
    日期:2009.1.5
    A convergent synthesis of bafilomycinA1 (see structure) is presented, and relies on the Zn(OTf)2‐mediated diastereoselective addition of alkynes to aldehydes. The coupling of a complex enyne with a sensitive aldehyde in the key step, in combination with a novel strategy for a chemoselective trans‐reduction of the enyne, establishes an alternative to standard palladium‐catalyzed cross‐coupling strategies
    提出了聚合反应的bafilomycin A 1(见结构),并依赖于炔烃醛类的Zn(OTf)2介导的非对映选择性加成。在关键步骤中,将复杂的烯炔与敏感的醛偶联,再结合用于烯炔的化学选择性反式还原的新策略,为形成1,3的标准催化交叉偶联策略提供了另一种选择-二烯。
  • Total Synthesis of Amphirionin-4
    作者:Yusuke Ogura、Hikaru Sato、Shigefumi Kuwahara
    DOI:10.1021/acs.orglett.6b00883
    日期:2016.5.20
    An expeditious enantioselective total synthesis of amphirionin-4, a remarkably potent promoter of the proliferation of ST-2 cells, has been achieved from (+/-)-(E)-1,4-hexadien-3-ol by an 8-pot sequence that features the Sharpless kinetic resolution, iodoetherification, and the CBS reduction to install the stereocenters, utilization of four one pot transformations to streamline the synthetic process, and the Stille coupling reaction at nearly the center of the target molecule to complete the total synthesis.
