  • Total synthesis of (+)-kalafungin using a tandem Michael–Dieckmann approach
    作者:Christopher D. Donner
    DOI:10.1016/j.tetlet.2007.10.058
    日期:2007.12
    A stereoselective synthesis of the antibiotic kalafungin 1 is reported. A key step involved the tandem Michael–Dieckmann reaction between methyl 2-methoxy-6-methylbenzoate 11 and the α,β-unsaturated lactone (R)-6-(2-(tert-butyldimethylsilyloxy)ethyl)-4-methoxy-5,6-dihydropyran-2-one 10, which was prepared from (S)-aspartic acid. The C5 alkyl substituent was introduced by the use of methylmagnesium
    据报道,抗生素kalafungin 1的立体选择性合成。关键步骤涉及2-甲氧基-6-甲基苯甲酸甲酯11与α,β-不饱和内酯(R)-6-(2-(叔丁基二甲基甲硅烷氧基)乙基)-4-甲氧基-5之间的串联Michael-Dieckmann反应由(S)-天冬氨酸制备的1,6-二氢吡喃-2-酮10。通过使用甲基溴化镁和随后的立体选择性还原来引入C 5烷基取代基。一连串的氧化反应,继之以酸催化的差向异构化,传递了(+)-卡拉芬净1。
  • Naphthopyranone synthesis via the tandem Michael–Dieckmann reaction of ortho-toluates with 5,6-dihydropyran-2-ones
    作者:Nichole P.H. Tan、Christopher D. Donner
    DOI:10.1016/j.tetlet.2008.04.112
    日期:2008.6
    The tandem Michael-Dieckmann reaction between a series of ortho-toluates and the alpha,beta-unsaturated lactone 25 is described. The tandem reaction delivers substituted naphthopyranones in moderate (20-49%) yields, whilst limitations in the tolerance of this reaction for different substituents on the ortho-toluate are identified.

  • The divergent asymmetric synthesis of kalafungin, 5-epi-frenolicin B and related pyranonaphthoquinone antibiotics
    作者:Christopher D. Donner
    DOI:10.1016/j.tet.2012.10.012
    日期:2013.1
    A divergent, asymmetric method for the synthesis of pyranonaphthoquinones is reported. The synthetic strategy applies a Staunton–Weinreb annulation between substituted ortho-toluates and the (R)-pyran-2-one 7 to construct the key naphthopyranone intermediates. Stereoselective introduction of either a methyl or propyl C5 alkyl substituent by use of Grignard addition/silane-mediated reduction and a sequence
    报道了一种不同的,不对称的吡喃并萘醌合成方法。合成策略在取代的邻甲苯酸酯和(R)-吡喃-2-酮7之间应用Staunton-Weinreb环空法来构建关键的萘并吡喃酮中间体。立体选择性引入或者是甲基或丙基C5烷基通过使用Grignard加成/硅烷介导的还原和氧化反应的一个序列的取代基得到了一系列pyranonaphthoquinones包括kalafungin的1,5-外延-9- methoxykalafungin 34和5-外延-frenolicin乙24。
