摘要用三乙酸硼醚酯诱导的乙酸3-溴-2-溴甲基丙-1-醇糖基化反应得到以下d系列糖的标题糖苷:Glc p,Gal p,Glc p A,GlcNPhth p,Xyl p ,β-Galp-(1→4)-Glc p和α-Galp-(1→4)-Gal p。用链烷硫醇和碳酸铯在N,N-二甲基甲酰胺中处理完全乙酰化的糖苷,然后脱乙酰化,得到相应的双硫化糖脂。
Propanol derivatives of formula (I) wherein X is a leaving group; R.sub.1 is H or a protecting group; and R.sub.2 is H, and R.sub.3 is a group--CH.sub.2 Y wherein Y is a leaving group; or R.sub.2 and R.sub.3 together form .dbd.CH.sub.2. The propanol derivatives of the formula (I) are useful as multifunctional alkylating agents.
