  • Kinetic Resolution of Racemic 2-Hydroxy-γ-butyrolactones by Asymmetric Esterification Using Diphenylacetic Acid with Pivalic Anhydride and a Chiral Acyl-Transfer Catalyst
    作者:Kenya Nakata、Kouya Gotoh、Keisuke Ono、Kengo Futami、Isamu Shiina

    日期:2013.3.15
    Various optically active 2-hydroxy-γ-butyrolactone derivatives are produced via the kinetic resolution of racemic 2-hydroxy-γ-butyrolactones with diphenylacetic acid using pivalic anhydride and (R)-benzotetramisole ((R)-BTM), a chiral acyl-transfer catalyst. Importantly, the substrate scope of this novel protocol is fairly broad (12 examples, s-value; up to over 1000). In addition, we succeeded in
    使用新戊酸酐和(R)-苯并四咪唑((R)-BTM),手性酰基-转移催化剂。重要的是,该新颖方案的底物范围相当广泛(12个例子,s值;最大超过1000)。此外,我们通过理论计算成功地揭示了提供高对映选择性的反应机理,并阐述了2-羟基内酯在C-3位置的取代基效应。
  • First enantioselective synthesis of (+)-(3R,3aS,6aS)-3-hydroxy-3,3a,4,6a-tetrahydrocyclopenta[b]furan-2-one — a versatile chiral heterocyclic building block
    作者:Steffen Kudis、Günter Helmchen
    DOI:10.1016/s0040-4020(98)00497-9
    日期:1998.8
    phosphinooxazoline 2 as chiral ligand enantiomeric excess of > 99% and > 90% yield were obtained. Alkylation products were transformed in three steps to (+)-(3R,3aS,6aS)-3-hydroxy-3,3a,4,6a-tetrahydrocyclopenta[b]furan-2-one (1a) in up to 52 % yield.

  • Synthesis of (+)-brefeldin-A
    作者:Andrew J. Carnell、Guy Casy、Gilles Gorins、Arefeh Kompany-Saeid、Ray McCague、Horacio F. Olivo、Stanley M. Roberts、Andrew J. Willetts
    DOI:10.1039/p19940003431

    Two routes to (+)-brefeldin A have been investigated. In one the bicyclic ketone 2 was transformed into the hydroxy lactone 7. Subsequent reduction, opening of the heterocyclic ring and epimerization furnished the aldehyde 13. Further steps towards the natural product from this late stage intermediate 13 were not investigated. in the second route, the readily available hydroxy lactone 17 was converted into the enone 22. Conjugate addition of the requisite cuprate reagent to this enone afforded the 3,4-disubstituted cyclopentanone 24 which was converted into brefeldin-A 29 in five steps.
  • Facile synthesis of (+)-brefeldin a utilizing two optically active synthons prepared by different enzyme-catalysed reactions

    日期:——
    The lactone 4a and the alcohol 6(both available in optically active form from biocatalytic processes) have been used as synthons in the preparation of (+)-brefeldin A.
