  • Stereochemical assignment of the fungal metabolite xestodecalactone A by total synthesis
    作者:Gerhard Bringmann、Gerhard Lang、Manuela Michel、Markus Heubes
    DOI:10.1016/j.tetlet.2004.02.005
    日期:2004.3
    The first synthesis of the macrocyclic natural product xestodecalactone A, a metabolite of a sponge-derived fungus, is described. By the use of methyl 5-hydroxyhexanoate in its R- or S-configured form, or as its racemate as the precursors, both enantiomers of xestodecalactone A as well as the racemic compound were obtained. Comparison of these synthetic products with the natural product by circular
    描述了大环天​​然产物xestodecalactone A(海绵衍生真菌的代谢产物)的首次合成。通过使用R-或S-构型的形式或作为其外消旋体的5-羟基己酸甲酯作为前体,获得了异十二烷内酯A的对映异构体以及外消旋化合物。这些合成产物与天然产物通过圆二色性(CD)光谱法和通过HPLC在手性相上的比较揭示了天然产物具有(R)-构型。

    DOI:10.1021/ja064270e
    日期:2006.11.1
    A concise total synthesis of xestodecalactone A, utilizing a Diels-Alder strategy is described. The focal Diels-Alder reaction relied on an "ynoate" dienophile to rapidly assemble the required resorcylinic acid scaffold. During this study, Diels-Alder cycloaddition reactions involving 1,3-disubstituted nonequivalent allene dienophiles were studied, and some surprising results were encountered.

    日期:2019.6.7
    A unified and concise approach to the synthesis of nine curvularin-type metabolites and two analogues has been developed with few steps and high yields. Among them, sumalactones A–D were synthesized for the first time. The key steps in this approach included esterification, Friedel–Crafts acylation, and ring-closing metathesis (or cross metathesis).

  • Convergent synthesis of (+)-xestodecalactone A via a Pd-catalyzed α-arylation reaction
    作者:Dripta De Joarder、Michael P. Jennings
    DOI:10.1016/j.tetlet.2013.05.068
    日期:2013.7
    The convergent total synthesis of (+)-xestodecalactone A (1) is reported. In addition, a formal synthesis of (+)-sporostatin has been accomplished by means of intercepting a previously reported intermediate en route to I. The key reaction utilized was a convergent Pd-catalyzed alpha-arylation between a boronic acid and an alpha-bromoester. (C) 2013 Elsevier Ltd. All rights reserved.
