conditions of acid hydrolysis, acetolysis, and methanolysis, 2-acet-amido-2-deoxy-, and 2-deoxy-1,3,4,5,6-penta- O -methyl-2-( N -methylacetamido)- d glucitol and - d -galactitol undergo O -demethylation, the N -methyl group being preserved. Upon acetylation, mainly 2-acetamido-I- O -acetyl-2-deoxy-, and 1- O -acetyl-2-deoxy-3,4,5,6-tetra- O -methyl-2-( N -methylacetamido)hexitol derivatives are formed
摘要在酸水解,乙酰化和甲醇分解的条件下,2-乙酰氨基-2-脱氧-和2-脱氧-1,3,4,5,6-戊-O-甲基-2-(N-甲基乙酰胺-d-葡萄糖醇和-d-半乳糖醇进行O-脱甲基化,保留N-甲基。乙酰化后,主要是2-乙酰氨基-I-O-乙酰基-2-脱氧-和1-O-乙酰基-2-脱氧-3,4,5,6-四-O-甲基-2-(N-甲基乙酰胺基形成己糖醇衍生物 没有检测到先前假定的2-(N-乙酰基乙酰胺基)-2-脱氧-1,3,4,5,6-戊-O-甲基己糖醇衍生物。
