1,3,4,6-四-O-乙酰基-2-脱氧-2-氨基-β-D-葡萄糖的研制

Study on the Preparation of 1,3,4,6-tetra-O-acetyl-2-deoxy-2-amido-β-D-Glucopyranose

分别采用苯甲醛、2,3,4-三甲氧基苯甲醛和4-甲氧基苯甲醛作为氨基保护基,对氨基葡萄糖衍生物的重要中间体1,3,4,6-四-O-乙酰基-2-脱氧-2-氨基-β-D-吡喃葡萄糖加以研制.结果显示,试验的同等条件下,只有用4-甲氧基苯甲醛保护成功,且效果良好.

Benzaldehyde,2,3,4-Trimethoxybenzaldehyde and 4-methyl benzaldehyde are separately used here as protecting group for amino group on D-glucosamine to prepare 1,3,4,6-tetra-O-acetyl-2-deoxy-2-amido-β-D-glucopyranose.The result shows,in the same experimental conditions,only 4-methyl benzaldehyde protects amino group successfully and effectively.
