  biologically active galactosyl ceramide KRN7000 and other α-glycolipids with excellent yield and stereoselectivity by using per-O-silylated galactosyl iodide and stannyl ethers as glycosylation partners. This direct glycosylation reaction reduces the overall number of steps and provides rapid access to biologically important α-galactosyl ceramide derivatives. (© Wiley-VCH Verlag GmbH & Co.

  在此，我们描述了一种简单实用的协议，用于通过使用过 O-甲硅烷基化半乳糖基碘和甲锡醚作为糖基化伙伴，以优异的产量和立体选择性获取生物活性半乳糖神经酰胺 KRN7000 和其他 α-糖脂。这种直接的糖基化反应减少了总步骤数，并提供了对生物学上重要的 α-半乳糖神经酰胺衍生物的快速获取。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
