  • Enantioselective Total Synthesis of the Unnatural and the Natural Stereoisomers of Vittatalactone

    of the cucumber beetle. In this context, we developed the asymmetric total synthesis of the aggregation pheromone of A. vittatum, Vittatalactone, to determine its absolute configuration and to further examine the pheromone response in field studies. The synthesis features an enzyme-catalyzed approach toward the deoxypropionate structural motif. A preformed organocopper reagent could then be coupled in

    A short sequence comprising an oxy-Cope rearrangement, iridium-catalyzed hydrogenation, and enolate methylation provides trideoxypropionates with excellent diastereocontrol. A straightforward synthesis of the cucumber beetle pheromone (+)-vittatalactone illustrates this new strategy.

    日期:2011.8
    An enantioselective asymmetric total synthesis of (+)-vittatalactone has been accomplished employing enzymatic desymmetrization approach to create two methyl chiral centres. Other key steps involved are Wittig reaction, Evan's asymmetric alkylation, hydroboration, TEMPO-BAIB-mediated selective oxidation of 1,3-diol and lactonization mediated by p-toluenesulfonyl chloride. The total synthesis was achieved

  • A General, Asymmetric, and Noniterative Synthesis of Trideoxypropionates. Straightforward Syntheses of the Pheromones (+)-Vittatalactone and (+)-Norvittatalactone
    作者:Christian F. Weise、Matthias C. Pischl、Andreas Pfaltz、Christoph Schneider
    DOI:10.1021/jo202330b
    日期:2012.2.3
    A novel, highly stereocontrolled, and very flexible synthetic access to biologically relevant trideoxypropionate building blocks in optically pure form has been developed. On the basis of a three-step sequence comprising a thermal oxy-Cope rearrangement, an iridium-catalyzed hydrogenation, and an auxiliary-controlled enolate methylation, trideoxypropionates with easily adjustable relative configuration were synthesized in excellent yields. In addition, the functionalized end groups allow for chemoselective manipulations and further elongation of the chain. The underlying strategy constitutes the first noniterative process for the assembly of polydeoxypropionates and has further been applied in total syntheses of the pheromones (+)-vittatalactone and (+)-norvittatalactone, which had been isolated from the striped cucumber beetle Acalymma vittatum.
