A one-pot C2-acetamidomannosylation reaction for the synthesis of 2-N-acetylamino-2-deoxy-α-d-mannopyranosides from glucals is described. Glucal donors are activated by the reagent combination of 2,8-dimethyldibenzothiophene-5-oxide (DMDBTO) and trifluoromethanesulfonic anhydride. Upon subsequent addition of N-(TMS)acetamide and an appropriate glycosyl acceptor, the corresponding C2-acetamidomannopyranosides
描述了一种用于从葡糖合成2- N-乙酰氨基-2-脱氧-α-d-甘露吡喃糖苷的一锅C 2-乙酰氨基甘露糖基化反应。葡萄糖供体被2,8-二甲基二苯并噻吩-5-氧化物(DMDBTO)和三氟甲磺酸酐的试剂组合激活。随后加入N-(TMS)乙酰胺和合适的糖基受体,形成相应的C 2-乙酰氨基甘露聚糖吡喃糖苷。
