    摘要: The subject matter of the present invention is the novel molecules of formulae E, E' and F. These molecules prove to be synthesis intermediates that are very advantageous for the manufacture of derivatives of sphingosine or of ceramides functionalized in position 1, with good yields, in which R
    1 and R
    2 are fatty chains, R
    3 is an alkyl group and R
    4 is a protective group for alcohol functions. Another subject of the invention is the use of the intermediates of type F for converting same into intermediates of type G, by means of reduction in the presence of lithium borohydride. The G molecules are precursors that are known to make it possible to obtain sphingolipids or sphingomyelin.

    摘要翻译: 本发明的主题是式餐饮E的新分子,E“和F这些分子被证明是合成中间体确实是鞘氨醇或在位置1官能神经酰胺的衍生物的制备是非常有利的,以良好的收率, 其中R 1和R 2是脂肪链,R 3是烷基且R 4为醇官能团的保护基。 本发明的另一主题是一种用于在硼氢化锂的存在下还原的转换成相同G型的中间体,借助于使用F型的中间体。 对于g分子前体确实是已知的,使之能够得到鞘脂类或鞘磷脂。
