The use of the intramolecular vinylogous aldolreaction for the preparation of an advanced intermediate for the synthesis of peloruside A is described. The reaction was applied to compound 19 and proceeds in high yield and good levels of diastereoselectivity. Application of the Achmatowicz reaction to this intermediate provided the corresponding pyranone, a late stage intermediate well positioned for
描述了分子内乙烯醇醛反应在制备用于合成 peloruside A 的高级中间体中的用途。将该反应应用于化合物19并以高产率和良好的非对映选择性进行。将 Achmatowicz 反应应用于该中间体提供了相应的吡喃酮,这是一种后期中间体,适合转化为天然产物。
