The syntheses of D-mannosamine 15, D-idosamine 16, D-altrosamine 19, and D-tallosamine 20 derivatives of 2-amino-2-deoxy-D-hexopyranoside-containing disaccharides were achieved by [3,3] sigmatropic rearrangement reaction of the disaccharide 13 having a 4-trichloroacetimidate-2-enoside group, prepared in turn by glycosylation of thioglycosyl donors using Pd(CH3CN)2Cl2-AgOTf as a promoter.
以 Pd(CH3CN)2Cl2-AgOTf 为促进剂,通过硫代糖基供体的糖基化反应,合成了含有 2-氨基-2-脱氧-D-吡喃己糖的二糖的 D-甘露胺 15、D-伊多糖胺 16、D-阿洛糖胺 19 和 D-塔洛糖胺 20 衍生物。
