from a vinyl epoxide, a divergent synthesis of four sphingosine isomers is described. The remaining four isomers can easily be synthesized using the same methodology. Although numerous syntheses of sphingosine have been published, this is the first general route leading to all eight isomers in this important compound class. The synthetic strategy relies on regioselective opening of a vinyl epoxide
从乙烯基环氧开始,描述了四种鞘氨醇异构体的发散合成。其余四个异构体可以使用相同的方法轻松合成。尽管已公开了许多鞘氨醇合成方法,但这是导致这一重要化合物类别中所有八个异构体的第一条通用途径。合成策略依赖于烯丙基位置的乙烯基环氧化物和乙烯基氮丙啶的区域选择性打开。
