  • Studied Directed toward the Synthesis of Phomenoic Acid. Part 2. Stereocontrolled Synthesis of the C(7)-to-C(14) Segment

    corresponding to the C(7)-to-C(14) segment of phomenoic acid (1). Attempts to improve the yields by applying a Julia coupling of (R)-23, which was prepared from (2E,4R)-7, with (R)-24 were unsuccessful. Finally, the coupling of the iodo derivative (2E,4S)-28 with the lithiated derivative of 1,3-dithiane 30 by the Corey-Seebach ‘Umpolung’ led to (3S,4E)-32 which is a derivative of the C(7)-to-C(14) segment
    从酯(2 E,4 S)-6和(2 E,4 R)-6开始,溴醛(S)-9和(R)-9以及溴代醇(S)-10和(R)-10,分别准备。溴醇(R)-8被转化为二醇(2 E,4 R)-16。后者的臭氧分解产生醛(R)-17,该醛被(a )转化为Wittig反应至(2 R,4 E,6 R)-18,对应于phomenoic acid(1)的C(7)-C(14)段。通过应用由(2 E,4 R)-7制备的(R)-23与(R)-24的Julia偶联来提高收率的尝试均未成功。最后,将碘代衍生物的偶联(2 ë,4小号) - 28与1,3-二噻烷的锂化衍生物30由科里-Seebach的'极性转换'导致(3小号,4 ë) - 32这是一种衍生物的C(7)的-to-C(14)的段1,适合于进一步转化。
  • Studies Directed toward the Synthesis of Phomenoic Acid. Part 1. Enantioselective synthesis of the C(1)-to-C(6) segment

    analysis, a concept for the synthesis of all stereoisomers of the C(1)-to-C(6) segment of phomenoic acid has been developed. Both enantiomers of the chiral synthon 9 were prepared starting from rac-epoxy-diester 10. They were converted to both enantiomers of the epoxyalcohol, 16 and 21, respectively, using Sharpless epoxydation. They served as building blocks for the synthesis of the tetrol derivatives
    基于逆合成分析,已开发了一种合成phomenoic acid C(1)至C(6)片段的所有立体异构体的概念。从外消旋-环氧-二酯10开始制备手性合成子9的两个对映体。使用Sharpless环氧化将它们分别转化为环氧醇的两种对映体16和21。它们充当合成四氢萘酚衍生物20和22的基础, 分别。所有四种立体异构体均以光学纯的形式获得。它们包含受保护的官能团的正确组装,考虑到进一步的转化,允许选择性地脱保护。

    feature of this synthetic route involves the highly stereoselective construction of the vinyl-substituted bicyclic lactone by an intramolecular Pd(0)-catalyzed allylic alkylation and its facile conversion to the hydroxy bicyclic lactone skeleton of bacillariolide III, induced by stereoselective vinylcerium addition to the aldehyde. In addition, the (Z)-pentenoic acid was efficiently introduced by the
    [反应:见正文] bacillariolide III的不对称全合成反应是通过15个线性步骤完成的,总收率为14.6%。该合成途径的关键特征涉及通过分子内Pd(0)催化的烯丙基烷基化反应对乙烯基取代的双环内酯进行高度立体选择性的构建,以及通过向立体选择性乙烯基铈中添加立体定向而诱导的其容易地转化为芽孢杆菌内酯III的羟基双环内酯骨架。醛。另外,通过内部羟基束缚的闭环复分解(RCM)有效地引入了(Z)-戊烯酸。
