Abstract The total synthesis of methyl β- d -arabinofuranoside 5-( myo -inositol 1-phosphate), the capping motif of the lipoarabinomannan (LAM) of Mycobacterium smegmatis , has been completed. The stereoselective synthesis of β- d -arabinofuranosides has been achieved via an internal aglycon delivery approach using Ogawa and Ito’s method. Coupling with enantiomeric myo -inositol derivatives gave the
摘要已成功完成耻垢分枝杆菌脂环阿拉伯甘露聚糖(LAM)的加帽基序甲基β-d-阿拉伯呋喃糖苷5-(肌醇-1-磷酸)的合成。β-d-阿拉伯呋喃糖苷的立体选择性合成已通过使用Ogawa和Ito方法的内部糖苷配基递送方法实现。与对映异构的肌醇衍生物偶联,以良好的总收率得到非对映异构的标题化合物。与天然产物的比较牢固地建立了提议的用于LAM的封端的结构,但是未确定肌醇基部分的绝对构型。
