    3S)-epoxy butanoate 7 followed by methylation gave the tetrahydro-2-furylidene acetate (−)-10, which was converted to the left-half aldehyde (+)-3. A Wittig reaction between (+)-4 and the phosphoranylide derived from the bithiazole-type phosphonium iodide 4 using lithium bis(trimethylsilyl)amide afforded the (+)-cystothiazole A (2).

  • Natural product-derived building blocks for combinatorial synthesis. Part 1. Fragmentation of natural products from myxobacteria
    作者:Jutta Niggemann、Katrin Michaelis、Ronald Frank、Norbert Zander、Gerhard Höfle
    DOI:10.1039/b206953a
    日期:——
    Novel and unique chiral building blocks of high structural diversity were obtained by selective chemical fragmentation of natural products from myxobacteria. Subsequent modification reactions provided primary alcohol and carboxylic acid derivatives, which are suitable for the construction of combinatorial chemical libraries. The single SPOT synthesis of a hybrid structure on a polypropylene membrane was employed to demonstrate the chemical recombination of such rare building blocks on a micro-scale.

  • Formal total syntheses of Myxothiazols by three different approaches starting from benzyloxyacetaldehyde
    作者:Dirk Backhaus
    DOI:10.1016/s0040-4039(00)00147-7
    日期:2000.3
    An efficient entry into the key intermediate for the total synthesis of myxothiazol A(1) and related structures is described. We investigated three different approaches for building up the carbon framework starting from benzyloxyacetaldehyde and subjecting this to an aldol reaction, a titanium tetrachloride-mediated aldol reaction of a protected beta-ketoester and a Barbier-type reaction using zinc or indium, respectively. The latter proved to be the longer (seven steps), but more efficient route, with 15% overall yield. (C) 2000 Elsevier Science Ltd. All rights reserved.
  • Total Synthesis of (+)-Cystothiazole A
    作者:Patrick L. DeRoy、André B. Charette
    DOI:10.1021/ol035600s
    日期:2003.10.1
    The total synthesis of cystothiazole A is described. Key steps of the synthesis include an Evans asymmetric catalytic aldol reaction, which established the required C-4-C-5 stereochemistry. The [2,4']-bis(thiazole) was obtained applying our methodology of electrophilic activation of amide. Semistabilized Wittig reaction between the phosphonium salt 3 and the aldehyde 2 afforded 1 in nine linear steps and 38% overall yield.
