  • Epoxyamide-Based Strategy for the Synthesis of Polypropionate-Type Frameworks
    作者:Francisco Sarabia、Francisca Martín-Gálvez、Miguel García-Castro、Samy Chammaa、Antonio Sánchez-Ruiz、José F. Tejón-Blanco

    A new approach to the stereoselective synthesis of polypropionate-type frameworks is reported utilizing reactions of amide-stabilized sulfur ylides with chiral aldehydes. To establish a new strategy for macrolide fragment synthesis, the stereoselectivity of these reactions in the construction of epoxy amides was the most important aspect of this study. In this aspect, we found a strong influence of
    据报道,利用酰胺稳定的硫酰化物与手性醛的反应,可以合成一种新的聚丙烯酸酯类骨架立体选择合成方法。为了建立大环内酯片段合成的新策略,这些反应在环氧酰胺的构建中的立体选择性是这项研究的最重要方面。在这方面,我们发现起始醛中使用的保护基对其与硫代叶立德1反应的立体化学结果具有强烈影响。因此,与其他醛相比,许多醛显示出显着的立体分化,从而提供了主要的非对映异构体立体选择性差或没有。尽管在某些情况下在非对映异构体产量方面遇到了困难,

    The regioselective opening reaction of 2,3-epoxyanudes with Various nucleophiles offers a variety of beta-hydroxyamides with diverse synthetic utility depending on the introduced nucleophile. Due to the exclusive stereoselectivity in the formation of trans epoxyamides in reactions of aldehydes with stabilized sulfur ylides, We studied the isomerization of trans epoxyamides into the cis isomers with the objective of obtaining the corresponding syn opening products, which together with the anti isomers represent a variety of enantiomerically Pure building blocks.

  • Stereoselective synthesis of precursors of the macrolide antibiotics via reactions of sulfur ylides with chiral aldehydes
    作者:F.Jorge López-Herrera、Francisco Sarabia-García、Gracia María Pedraza-Cebrián、María Soledad Pino-González

    Reactions of stabilized sulfur ylides with chiral aldehydes provided epoxides with high stereoselectivity. The opening of the resulting epoxides with lithium dimethyl cuprate gave 2-methyl-3-hydroxy amides which represent potentially useful building blocks for the synthesis of macrolide natural products. These amides were transformed into chiral aldehydes, with a methyl group in the alpha-position, and were reacted, in a iterative process, with a sulfur ylide reagent to give, in high yield and stereoselectivity, the epoxides with the stereochemistry according to Felkin-Ahn control. Finally, opening of the epoxide with the Oilman reagent provided a compound with four stereocenters occurring in the macrolide-type of natural products. (C) 1999 Elsevier Science Ltd.
