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.
本发明的主题是公式E、E'和F的新型分子。这些分子被证明是合成中间体,非常有利于制造在1位功能化的鞘氨醇衍生物或鞘氨醯胺衍生物,收率良好,其中R1和R2是脂肪链,R3是烷基基团,R4是醇功能的保护基团。本发明的另一个主题是将F型中间体转化为G型中间体的用途,通过在锂硼氢化铝的存在下进行还原。G分子是已知的前体,可以用来获得鞘脂类或鞘磷脂。
