    Diastereoselective synthesis of (+)-nephrosterinic acid and (+)-protolichesterinic acid
    摘要:
    A diastereoselective synthesis of (+)-nephrosterinic acid and (+)-protolichesterinic acid, common members of the paraconic acids is described. The synthesis is based on a diastereoselective orthoester Johnson-Claisen rearrangement of a (Z)-allyl alcohol with a vicinal dioxolane moiety as key steps. The synthesis is completed in 10 steps and with overall yields of 15.9% for (+)-nephrosterinic acid and 16.4% for (+)-protolichesterinic acid. (C) 2012 Elsevier Ltd. All rights reserved.

  • Isolation and Asymmetric Total Synthesis of Fungal Secondary Metabolite Hygrophorone B<sup>12</sup>
    作者:Eileen Bette、Alexander Otto、Tobias Dräger、Kurt Merzweiler、Norbert Arnold、Ludger Wessjohann、Bernhard Westermann

    日期:2015.4
    has been isolated and subsquently synthesized in enantiomerically pure form. The total synthesis includes a Sharpless asymmetric dihydroxylation protocol as the stereodifferentiating step, followed by two diastereoselective aldol-type reactions. The approach allows the unambiguous control of all three stereogenic centres, and, furthermore, unequivocal determination of the relative and absolute configuration
    Hygrophorone B12 是来自 Hygrophorus abieticola 子实体的一种新的抗真菌成分,已被分离出来并随后以对映体纯的形式合成。全合成包括 Sharpless 不对称二羟基化方案作为立体分化步骤,然后是两个非对映选择性羟醛型反应。该方法允许对所有三个立体中心进行明确控制,此外,首次明确确定抗生素 hygrophorone B 的相对和绝对构型。
