    日期:2011.11
    of a trisaccharide found in the soil bacterium Geobacillus stearothermophilus. The phospholipid was assembled by the reaction of a peracetylated trisaccharide bearing an anomeric hydroxy group with phosphoramidite and subsequent oxidation to the phosphate. The final coupling step with undecaprenyl monophosphate followed by global acetate deprotection completed the total synthesis of the highly amphiphilic
    采用 (2+1) 糖基化方法构建了在土壤细菌嗜热脂肪地芽孢杆菌中发现的三糖的核心结构。磷脂是通过带有异头羟基的过乙酰化三糖与亚酰胺反应并随后氧化成磷酸盐来组装的。与十一碳烯磷酸酯偶联的最后一步,然后是全局乙酸酯去保护,完成了高度两亲性目标分子的全合成。

    Synthesis of a tetrasaccharide related to the repeating unit of the O-antigen from Escherichia coli K-12 is reported in the form of its octyl glycoside. Syntheses of the 1,2-cis glycosidic linkages have been accomplished by using NIS in conjunction with H(2)SO(4)-silica, and it was found to be stereoselective and productive. The synthesized tetrasaccharide will be utilized as the substrate for gal
