摘要
乙将未保护的D-葡萄糖与醋酸酐在高氯酸催化下制得全乙酰吡喃糖,不经分离直接与液溴和红磷反应合成了全乙酰吡喃溴代葡萄糖,分离收率达95%,其结构经核磁共振鉴定。
A convenient procedure was developed for the preparation of Acetobromo-a-D-glucose by trearment of free D-glucose with HClO_4(cat.) / A_(c2)O and Br_2/ P sequentially in one-pot,the product yield was 95%and charactered by NMR.
