  • Toward the synthesis of brevipolide H
    作者:Debendra K. Mohapatra、Suresh Kanikarapu、P. Ramesh Naidu、Jhillu S. Yadav
    DOI:10.1016/j.tetlet.2014.12.125
    日期:2015.2
    brevipolide H is described. The key reactions include Jørgensen’s asymmetric epoxidation, palladium-catalyzed regioselective opening of α,β-unsaturated γ,δ-epoxide, Charette’s modified Simmons–Smith cyclopropanation, anti-selective reduction of cyclopropyl containing α,β-unsaturated ketone, Brown allylation, and ring-closing metathesis reaction.

  • Synthesis of<i>N</i>-Bz-Protected D-Daunosamine and D-Ristosamine by Silica Gel Promoted Intramolecular Conjugate Addition of Trichloroacetimidates obtained from Osmundalactone and Its Epimer
    作者:Yoshitaka Matsushima、Jun Kino
    DOI:10.1002/ejoc.200901402
    日期:2010.4
    osmundalactone and its epimer unexpectedly undergo intramolecular conjugate addition during silica gel chromatography to produce oxazolines in excellent yields. The novel, simple synthesis of N-Bz-protected D-daunosamine and D-ristosamine from these oxazolines is described in this paper.
    由桂皮内酯及其差向异构体制备的三氯乙酰亚胺在硅胶色谱过程中出人意料地进行了分子内共轭加成,以优异的产率生产恶唑啉。本文描述了从这些恶唑啉中新颖、简单地合成 N-Bz 保护的 D-道诺胺和 D-利索胺。
  • Highly Regio- and Enantioselective Monoepoxidation of Conjugated Dienes
    作者:Michael Frohn、Molly Dalkiewicz、Yong Tu、Zhi-Xian Wang、Yian Shi
    DOI:10.1021/jo9721195
    日期:1998.5.1
    This paper describes a highly effective and mild asymmetric monoepoxidation method for conjugated dienes using a fructose-derived chiral ketone 1 as catalyst and Oxone as oxidant. The regioselectivies and enantioslectivies are very high in most cases. For unsymmetrical dienes, the regioselectivity can be regulated by using steric and electronic control. The olefin substrates include trans-disubstituted and trisubstituted olefins that can bear a wide range of functional groups such as hydroxyl groups, TBS ethers, or esters. The enantiomeric excesses for the major monoepoxides range from 89% to 97%. The epoxidation is believed to proceed via a spiro mode.
  • Synthesis of an insecticidal tetrahydroisocoumarin, (3R,4S,4aR)-4,8-dihydroxy-3-methyl-3,4,4a,5-tetrahydro-1H-2-benzopyran-1-one
    作者:Kanako Uchida、Ken Ishigami、Hidenori Watanabe、Takeshi Kitahara
    DOI:10.1016/j.tet.2006.11.006
    日期:2007.1
    The insecticidal tetrahydroisocoumarin, (3R,4S,4aR)-4,8-dihydroxy-3-methyl-3,4,4a,5-tetrahydro-1H-2-benzopyran-1-one, was synthesized as a racemate and as an optically active form using one-potesterification-Michael addition-aldol reaction of delta-hydroxy-alpha,beta-unsaturated aldehyde and diketene as a key step.

  • Palladium-catalysed regio- and stereoselective arylative substitution of γ,δ-epoxy-α,β-unsaturated esters and amides by sodium tetraaryl borates
    作者:Yasemin Bilgi、Melih Kuş、Levent Artok
    DOI:10.1039/d0ob01226b
    日期:——
    Palladium-catalysed reactions of γ,δ-epoxy-α,β-unsaturated esters and amides with NaBAr4 reagents proceeded regio- and stereoselectively, producing allylic homoallyl alcohols with aryl-substituents in the allylic position for a wide range of substrates. AsPh3 was found to be a competent ligand for the arylation reaction, whereas phosphine ligand/Lewis acidic organoboron combinations favoured the substitution
    钯催化的 γ,δ-环氧-α,β-不饱和酯和酰胺与 NaBAr 4试剂的反应以区域选择性和立体选择性进行,产生在烯丙基位置具有芳基取代基的烯丙基高烯丙基醇,适用于各种底物。AsPh 3被发现是芳基化反应的有效配体,而膦配体/Lewis 酸性有机硼组合有利于氧亲核试剂(例如H 2 O、ROH)的取代反应。
