assembled by PhSeOTf-promoted glycosylation of the known glucosamine precursor, t-butyldimethylsilyl 2-azido-3,6-di-O-benzyl-2-deoxy-beta-D-glucopyranoside (8) with protected 1-methylthio mono-, di-, and trimannosides 7a-c, and, after conversion into glycosyl fluorides, Cp2ZrCl2- AgOTf-promoted glycosylation of differentially protected optically pure 1D-myo-inositol 11. The syntheses were completed by installing
报道了在结构上与天然肌醇磷酸聚糖有关的三糖,四糖和五糖环状磷酸酯1-5的有效合成。通过PhSeOTf促进的已知氨基葡萄糖前体,叔丁基二甲基甲硅烷基2-叠氮基3,6-二-O-苄基-2-脱氧-β-D-D-吡喃葡萄糖苷(8)的PhSeOTf促进糖基化组装而得单,二和三甘露糖苷7a-c,并在转化为糖基氟化物后,由Cp2ZrCl2- AgOTf促进了差异保护的光学纯1D-肌醇11的糖基化反应。最后通过溶解金属还原除去所有保护基。
