    Enantiospecific Synthesis of (+)- and (−)-Ferruginine from l-Glutamic Acid. Synthesis of Tropanes via Intramolecular Iminium Ion Cyclization
    摘要:
    Iminium ions, generated by decarbonylation of N-benzyl-5-[1-(methoxycarbonyl)-4-oxopentyl]-prolines, prolines, undergo intramolecular cyclization to afford 2,4-disubstituted tropanes in good yields. This transformation is also shown to be a stereospecific reaction. The value of these substituted tropanes has been demonstrated by functional group manipulation, leading to the enantiospecific synthesis of (+)-ferruginine, an alkaloid isolated from Darlinga ferruginea, and its unnatural enantiomer, (-)-ferruginine.

  • Jasmonoid Synthesis from<i>sci</i>-4-Heptenoic Acid
    作者:Toshio Sato、Tatsuo Kawara、Kazumi Sakata、Tamotsu Fujisawa

    日期:1981.2
    Jasmonoids with cis-2-pentenyl side chain such as cis-jasmone, methyl jasmonate, and jasmolone were easily synthesized from cis-4-heptenoic acid obtained by the ring opening reaction of β-propiolactone with di-cis-butenylcuprate.
    通过β-丙内酯与二-顺-丁烯基铜酸盐的开环反应获得的顺-4-庚烯酸可以很容易地合成具有顺-2-戊烯基侧链的茉莉酮类化合物,如顺-茉莉酮、茉莉酸甲酯和茉莉酮酮。
  • A new ready route to 1,4-ketoaldehydes and 1,4-diketones with application to the synthesis of z-jasmone and dihydrojasmone
    作者:V Fiandanese、G Marchese、F Naso
    DOI:10.1016/0040-4039(88)85300-0
    日期:1988.1
    A new three-step synthesis in good overall yield of 1,4-ketoaldehydes and 1,4-diketones is described. The method involves two sequential coupling reactions of Grignard reagents with S-phenyl carbonochloridothioate in the presence of nickel(II) or iron(III) complexes as catalysts. Application of this reaction to the synthesis of Z-jasmone and dihydrojasmone is also described.
    描述了一种新的三步合成法,其合成了1,4-酮醛和1,4-二酮的良好总收率。该方法包括在镍(II)或铁(III)配合物作为催化剂存在下,格氏试剂与S-苯基碳酰氯硫代酸酯的两个顺序偶联反应。还描述了该反应在Z-茉莉酮和二氢茉莉酮的合成中的应用。

    involves late-stage fragment coupling of a tertiary-carbon radical and an electron-deficient double bond to form vicinal quaternary and tertiary stereocenters with high fidelity. A stereoselective Mukaiyama hydration is the key step in the subsequent elaboration of the cis-2,8-dioxabicyclo[3.3.0]octan-3-one moiety. This strategy was utilized in enantioselective total syntheses of (−)-macfarlandin C and
    描述了一种策略的发展演变,该策略可访问带有凹取代的顺式-2,8-二氧杂双环[3.3.0] octan-3-one片段的海绵状二萜类化合物。该方法涉及叔碳自由基和缺电子双键的后期片段偶联,以形成具有高保真度的邻近的季四级和三级立体中心。立体选择性的Mukaiyama水合是随后修饰顺式-2,8-二氧杂双环[3.3.0] octan-3-one部分的关键步骤。该策略用于(-)-macfarlandin C和(+)-dendrillolide A的对映选择性总合成中。在(-)-macfarlandin C的构建过程中开发了对映纯四甲基八氢萘的有效构造。
  • Total Synthesis of Panaginsene with Structural Revision
    作者:Sujeong Geum、Hee-Yoon Lee
    DOI:10.1021/ol500849m
    日期:2014.5.2
    A facile total synthesis of the reported structure for panaginsene through a trimethylenemethane (TMM) diyl mediated tandem cycloaddition reaction revealed that the spectroscopic data of the synthesized structure did not match with the data of the natural product. The total synthesis of the stereoisomer of the reported structure confirmed that the correct structure of panaginsene was the 11-epi stereoisomer
