However, their preparation in enantiomerically pure forms takes many efforts. Here, we synthetized all stereoisomers of these compounds by application of enantioselective catalysis and we revealed, that more easily available racemic forms exhibit similar cytotoxicity as enantiomerically pure forms.
从一些海洋海绵中分离得到的鞘氨醇碱Clavaminol A和Xestoaminol C具有令人感兴趣的细胞毒性。然而,以对映体纯形式制备它们需要付出很多努力。在这里,我们通过应用对映选择性催化合成了这些化合物的所有立体异构体,并且我们发现,更容易获得的外消旋形式表现出与对映体纯形式相似的细胞毒性。
