摘　　要：手性氨基醇作为催化剂广泛应用于多种不对称合成反应中.以氨基葡萄糖为原料设计合成一种新型手性β-氨基醇.氨基葡萄糖盐酸盐首先与氯甲酸甲酯缩合,再先后经过甲基化、苄叉保护、碱性水解反应,得4,6-O-苄叉基-2-脱氧-2-氨基-α-D-吡喃葡萄糖甲苷.4步反应总收率35%,对目标化合物及反应中间体的结构均进行1H NMR表征.Chiral amino alcohol is widely used in a variety of asymmetric reactions as catalysts.A new kind of chiral β-amino alcohol,methyl 4,6-O-benzylidenen-2-deoxy-2-amino-α-D-glucopyranoside,was synthesized by a four-step reaction starting from D-glucosamine hydrochloride commercially available.Firstly,D-glucosamine hydrochloride was condensed with methyl chloroformate under the catalyst of sodium carbonate.Then,the obtained product underwent methylation,benzylidene protection,and alkaline hydrolysis successively.The total yield was 35%,and the target compound and the key intermediates were characterized by^1 H NMR.
