We herein report a faster and less cumbersome synthesis of the biologically attractive, α-galactosyl ceramide (α-GalCer), known as KRN7000, and its analogues. More importantly, the use of a silicon tethered intramolecular glycosylation reaction gave easy access to the diglycosyl ceramide Gal(α1→2)GalCer, which has been shown to require uptake and processing to the biologically active α-GalCer derivative
我们在此报告了具有生物学吸引力的 α-半乳糖神经酰胺 (α-GalCer)(称为 KRN7000)及其类似物的更快、更简便的合成。更重要的是,使用硅系链分子内糖基化反应可以轻松获得二糖基神经酰胺 Gal(α1 → 2)GalCer,其已被证明需要摄取和加工成具有生物活性的 α-GalCer 衍生物。
