Abstract Boron trifluoride etherate-induced glycosidation of 3-bromo-2-bromomethylpropan-1-ol with sugar acetates gave the title glycosides of the following sugars of the d series: Glc p , Gal p , Glc p A, GlcNPhth p , Xyl p , β-Gal p -(1→4)-Glc p , and α-Gal p -(1→4)-Gal p . Treatment of the fully acetylated glycosides with alkanethiols and cesium carbonate in N,N -dimethylformamide followed by deacetylation
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。
