Abstract 2‐Acetamido‐2‐deoxy‐β‐D‐mannopyranose (1) was glycosylated by the Fischer method using an acidic ion‐exchange resin as the catalyst to give α‐methyl glycoside 2. Selective pivaloylations of methyl 2‐acetamido‐2‐deoxy‐α‐D‐mannopyranoside (2) have been studied under various reaction conditions. Two partially pivaloylated products were submitted to additional acetylations. All structures were
摘要使用酸性离子交换树脂作为催化剂,通过费歇尔方法将2-乙酰胺基-2-脱氧-β-D-甘露吡喃糖(1)糖基化,得到α-甲基糖苷2。脱氧-α-D-甘露吡喃糖苷(2)已在各种反应条件下进行了研究。将两种部分聚乙烯吡咯烷化的产品进行了额外的乙酰化处理。通过NMR光谱确定所有结构。X射线分析确定了甲基2-乙酰氨基-2-脱氧-3,6-二-O-新戊酰-α-D-甘露吡喃糖苷的结构(4)。
