摘要

通过一种以多样性为导向的策略合成了α-/β-半乳糖基甘油酰胺（GalCer）和葡萄糖基甘油酰胺（GlcCer）衍生物，这些衍生物在6-C位上具有适合电子顺磁共振光谱研究的自由基标记。该策略还用于合成天然的 α-/β-GalCers 和 GlcCers。此外，所涉及的叠氮中间体是获得其他各种 GalCer 和 GlcCer 衍生物的灵活平台。

Synthesis of Spin-Labeled α-/β-Galactosylceramides and Glucosylceramides as Electron Paramagnetic Probes

α-/β-Galactosylceramide (GalCer) and glucosylceramide (GlcCer) derivatives having a radical label at the 6-C-position suitable for electron paramagnetic resonance spectroscopic studies were synthesized by a diversity-oriented strategy that is highlighted by the efficient glycosylation of a lipid precursor and late-stage ceramide assembly to enable lipid diversification. The strategy was also utilized to synthesize natural α-/β-GalCers and GlcCers. Furthermore, the involved azido-intermediates are flexible platforms to access various other GalCer and GlcCer derivatives.
