A flexible synthetic approach to biologically active sphingoid base-like compounds with a 3-amino-1,2-diol framework was achieved through a [3,3]-sigmatropic rearrangement and late stage olefin cross-metathesis as the key transformations. The stereochemistry of the newly created stereogenic centre was assigned via a single crystal X-ray analysis of the (4S,5R)-5-(hydroxymethyl)-4-vinyloxazolidine-2-thione
通过[3,3]-σ重排和后期烯烃交叉复分解作为关键转化,获得了一种具有3-氨基-1,2-二醇骨架的生物活性类鞘氨醇碱样化合物的灵活合成方法。通过(4S,5R)-5-(羟甲基)-4-乙烯基恶唑烷-2-硫酮的单晶X射线分析确定了新创建的立体异构中心的立体化学。为了合理化所观察到的氮杂-克莱森重排的立体选择性,进行了DFT计算。在七个人恶性细胞系的组上体外筛选靶向的异构类鞘氨醇碱基的抗癌活性。细胞活力实验表明,C17同源物比其C12同源物更具活性。
