(CH2)7Me or (CH2)12Me] was studied. Dimethyldioxirane was found to be the best oxidant for that purpose. Application of this epoxidation resulted in a new synthesis of the α-galactosylceramide KRN7000 (2), which has an enhancing effect on the activity of natural killer cells.
研究了两种鞘氨醇衍生物[3,R =(CH 2)7 Me或(CH 2)12 Me]在C-4处双键的非对映选择性环氧化。发现二甲基二环氧乙烷是用于该目的的最佳氧化剂。这种环氧化的应用导致了α-半乳糖基神经酰胺KRN7000(2)的新合成,该合成对自然杀伤细胞的活性具有增强作用。
