  • Tetrahydrofuran Formation through Intramolecular Iodoetherification: Mechanistic Insights into the Neighbouring-Group Participation of an Ester
    作者:Nicolás Veiga、Juan C. Ramos、Gustavo Seoane、Margarita Brovetto
    DOI:10.1002/ejoc.201700494
    日期:2017.7.17
    5-disubstituted THF rings, the presence of an ester in the side chain exerted a profound effect in the chemo- and diastereoselectivity of the reaction. When submitted to standard iodoetherification conditions, ester-containing substrates gave diastereomeric mixtures of THF rings, together with variable amounts of iodohydrins. Conversely, when the ester group is reduced to alcohol or ether, the corresponding
    在手性和构象限制的 3-丁烯基甲醇的碘醚化过程中,获得 2,5-二取代的 THF 环,侧链中酯的存在对反应的化学和非对映选择性产生了深远的影响。当处于标准的碘醚化条件下时,含酯的底物会产生 THF 环的非对映异构混合物以及不同数量的碘醇。相反,当酯基被还原为醇或醚时,可以更快地获得相应的反式-THF,具有完全的非对映选择性并且没有碘醇的污染。在这项工作中,揭示了受保护的 3-丁烯基甲醇的碘醚化的机理细节。结果表明,羰基降低了丙酮化物氧原子的亲核性,并通过羰基-碘鎓通过空间相互作用稳定了反应物。此外,它促进了稳定的 7 元羧基中间体的形成,导致活化障碍的增加和非酯类似物的反应非对映选择性的降低。
  • Concise Preparation of the Bis-THF Core of Annonaceous Acetogenins
    作者:Margarita Brovetto、Gustavo Seoane、Elisa Delgue
    DOI:10.1055/s-0035-1561494
    日期:——
    A concise preparation of the all-(R) threo/trans/threo/trans/threo bis-THF core present in natural acetogenins is presented. Starting from a terminal alkene, homometathesis and two consecutive stereoselective cyclizations afforded the bis-THF core through a short and efficient sequence. In addition, the isomeric erythro/trans/threo/trans/erythro bis-THF core was also synthesized in high yield. The starting alkene was previously prepared from a homochiral cis-diol derived from biotransformation of bromobenzene.
  • Chemoenzymatic Synthesis of <i>trans</i>-Tetrahydrofuran Cores of Annonaceous Acetogenins from Bromobenzene
    作者:Juan Carlos Ramos、Margarita Brovetto、Gustavo A. Seoane
    DOI:10.1021/ol400650v
    日期:2013.4.19
    Two types of trans-THF cores, present in acetogenins, have been synthesized by an intramolecular iodoetherification reaction. The starting alkenol was obtained in a few steps from a chiral cis-diol resulting from microbial oxidation of bromobenzene. The cyclization gave complete stereoselectivity for trans-THF cores with either (S,S) or (R,R) configurations at the THF chiral carbons.
    通过分子内的碘醚化反应已经合成了存在于产乙酸素中的两种类型的反式-THF核。分几步从溴苯的微生物氧化产生的手性顺式二醇中获得起始烯醇。环化作用使在THF手性碳原子上具有(S,S)或(R,R)构型的反式THF核具有完全的立体选择性。
  • A chemoenzymatic total synthesis of the phytotoxic undecenolide (−)-cladospolide A
    作者:Martin G. Banwell、David T. J. Loong
    DOI:10.1039/b401829j
    日期:——
    An eleven-step synthesis of the title compound (1) from biocatalytically-derived and enantiomerically pure ‘building blocks’ alcohol (R)-(−)-9 and ester 13 is described. Attempts to construct the twelve-membered lactone ring of cladospolide A in a direct manner by using a ring-closing metathesis (RCM) reaction failed. However, a ten-membered lactone, 19, could be constructed by such means and this was then subject to a two-carbon homologation sequence involving, inter alia, Wadsworth–Horner–Emmons and Yamaguchi lactonisation reactions in the closing stages of the synthesis. The impact of substituent stereochemistries and protecting groups on the RCM reaction leading to various ten-membered lactones is also described.
    标题化合物 (1) 的十一步合成方法被描述,它从生物催化衍生和光学纯的“构建块”醇 (R)-(+)-9 和酯 13 开始。试图通过环闭合复分解(RCM)反应直接构建十二元内酯环的 cladospolide A 失败了。然而,通过这种方法可以构建十元内酯 19,然后通过包括 Wadsworth-Horner-Emmons 和 Yamaguchi 内酯化反应在内的二碳同系化序列在合成的最后阶段进行处理。在导致各种十元内酯的 RCM 反应中,取代基立体化学和保护基团的影响也被描述。
